The CFTC will send a confirmation email upon successful completion of your Form 40.


3. Confirm with IBKR -  forward your confirmation email, or other evidence that you have submitted the Form 40 to This will assist to ensure that your account is not subject to CFTC directed restrictions or fines.



Overview of CFTC Form 40

The CFTC, the primary regulator of U.S. commodity futures markets and Futures Commission Merchants (FCMs), operates a comprehensive system of collecting information on market participants as part of its market surveillance and large trader reporting program.

IBKR, as a registered FCM providing clients with access to those markets, is obligated to report to the CFTC information on clients who hold a position in a quantity that exceeds defined thresholds (i.e., a "reportable position").  In order to report this information, IBKR requires clients trading U.S. futures or futures options to complete an online CFTC Ownership and Control Reporting form at the point the client requests futures trading permissions.

Once a client holds a "reportable position", the CFTC may then contact that client directly and require them to file  more detailed information via CFTC Form 40. The information required of this report includes the following:

  • Trader's name and address
  • Principal business
  • Form of ownership (e.g., individual, joint, partnership, corporation, trust, etc.)
  • Whether the reporting trader is registered under the Commodity Exchange Act
  • Whether the reporting trader controls trading for others
  • Whether any other person controls the trading of the reportable trader
  • Name and location of all firms through which the reportable trader carries accounts
  • Name and location of other persons providing a trading guarantee or having a financial interest in account of 10% or greater
  • Name of accounts not in the reporting trader's name in which the trader provides a guarantee or has a financial interest of 10% or more.

Clients who fail to complete this Form in a timely manner may be subject to trading restrictions and/or fines imposed by CFTC upon their account at the FCM.  It is therefore imperative that clients immediately respond to these CFTC requests.

To complete the CFTC Form 40, clients must first register for a CFTC Portal Account, an online process which is subject to a review period of 2 business days from the point of initial registration to acknowledgement of approval by the CFTC.  For information regarding this registration process and completing the Form 40, see KB3149.

IBKR OTC Futures on LME Metals – Facts and Q&A

The following article is intended to provide a general introduction to LME-based OTC Futures issued by IBKR.
Note: Residents of the US, Canada, Hong Kong, and Israel cannot trade IBKR LME OTC Futures.



IBKR LME OTC Futures provide clients synthetic access to the London Metal Exchange, a peer to peer exchange not generally available to non-member investors.

The LME OTC Futures are OTC derivative contracts with IBUK as the counterparty. The LME OTC Futures reference the corresponding LME future in terms of price, lot size, type and specification but are themselves not registered contracts. Physical delivery is not permitted.

IBKR LME OTC Futures are traded through your margin account, and you can therefore enter long as well as short leveraged positions. Margin rates equal those established by the LME. Like other futures they are risk-based (SPAN), and therefore variable. Current margins range between 6 and 9% depending on the contract.


IBKR offers OTC Futures on the 3rd Wednesday expirations for the following metals:

Metal IB Symbol Price USD/ Multiplier
High Grade Primary Aluminium AH Metric Ton 25
Copper Grade A CA Metric Ton 25
Primary Nickel NI Metric Ton 6
Standard Lead PB Metric Ton 25
Tin SNLME Metric Ton 5
Special High Grade Zinc ZSLME Metric Ton 25

3rd Wednesday Expirations

The LME features a range of contracts adapted to the needs of physical traders and hedgers. The principal among them are daily 3-month forwards used by physical traders to precisely match their hedges to their needs.

The 3rd Wednesday contracts are monthly contracts, like futures, and as such better adapted to the needs of financial traders. As the name suggests, they expire on the 3rd Wednesday of each month and, although physically settled on the LME, are strictly cash-settled at IBKR. The 3rd Wednesday contracts have become increasingly popular and account for 65% of open interest on the LME.

Quotes and Market Data

IBKR streams quotes from the LME (L2 market data) and does not widen the quote. Every client order is first hedged on exchange and the LME OTC order filled at the price of the hedge.

Cash Flows

Daily variation margin and realized P&L for the IBKR LME OTC Futures are cash-settled daily, like a standard future. By contrast, cash flows for the underlying LME contract are only settled after the contract has expired.


The margin requirements for the IBKR LME OTC Futures equal the requirement for the underlying contract on the LME. LME uses Standard Portfolio Analysis of Risk (SPAN) to calculate Initial Margin.

Like for other futures, the margin rates are established as an absolute value per contract and usually updated monthly.

Frequently asked Questions

What do I need to do to start trading LME OTC Futures?
You need to set up trading permission for United Kingdom Metals in Account Management. If you have an IB LLC or an IB UK account carried by IB LLC we will set up a new account segment (identified with your existing account number plus the suffix “F”). Once the set-up is confirmed you can begin to trade. You do not need to fund the F segment separately; funds will be automatically transferred from your main account to meet margin requirements.

How are my LME OTC Futures trades and positions reflected in my statements?
Your positions are held in a separate account segment identified by your primary account number with the suffix “F”. You can choose to view Activity Statements for the F-segment either separately or consolidated with your main account. You can make the choice in the statement window in Account Management.

What account protections apply when trading LME OTC Futures?
LME OTC Futures are contracts with IB UK as your counterparty, and are not traded on a regulated exchange and are not cleared on a central clearinghouse. Since IB UK is the counterparty to your trades, you are exposed to the financial and business risks, including credit risk, associated with dealing with IB UK. Please note however that all client funds are always fully segregated, including for institutional clients. IB UK is a participant in the UK Financial Services Compensation Scheme ("FSCS"). IB UK is not a member of the U.S. Securities Investor Protection Corporation (“SIPC”).

Can I trade LME OTC Futures over the phone?
No. In exceptional cases we may agree to process closing orders over the phone, but never opening orders.

MIFID II Commodity Position Limits


On 3 January 2018, a new Directive 2014/65/EC (“MiFID II”) and Regulation (EU) No 600/2014 (“MiFIR”) will become effective, introducing new requirements on position limits and position reporting for commodity derivatives and emission allowances.

National Competent Authorities (“NCAs”) (i.e. regulators) of each European Economic Area (“EEA”) Country will calculate the limits on the size of the net position that a person can hold in commodity derivatives traded on an EU venue or its “economically equivalent contracts” (“EEOTC”).

The European Securities and Markets Authority (“ESMA”) intends to publish approved position limits on its website.
Limits will be set for the spot month and all other months, for both physically settled and cash settled commodities.
Investment firms trading in commodity derivatives and emissions allowances are obliged, on a daily basis, to report
their own positions in commodity derivatives traded on a trading venue and EEOTC contracts, as well as those of
their clients and the clients of those clients until the end client is reached, to the NCA.

Clients holding positions have to be identified using specified National Identifiers for individuals and LEIs for
organisations under MiFID II.

Interactive Brokers’ Implementation of the Requirements

In order to comply with its reporting obligations, IB will not allow its clients to trade if they have not provided the
specific National Identifier or LEI that is necessary for reporting positions of in scope financial products.

Whenever possible, IB will act to prevent account holders from entering transactions that may result in a position
limit violation. This process will include monitoring account activity, sending a series of notifications intended to
allow the account holder to self-manage exposure and placing trading restrictions on accounts approaching a limit.

Examples of notifications which are sent via email, TWS bulletin and Message Center are as follows:

  1. Information Level: sent when the position exceeds 50% of the limit. Intended to inform as to the existence of the position limit and its level.
  2. Warning Level: sent when the position exceeds 70% of the limit. Intended to provide advance warning that account will be subject to trading restrictions should exposure increase to 90%.
  3. Restriction Level: sent when the position exceeds 90% of the limit. Provides notice that account is restricted to closing transactions until exposure has been reduced to 85%.

Risks of Volatility Products

Trading and investing in volatility-related Exchange-Traded Products (ETPs) is not appropriate for all investors and presents different risks than other types of products. Among other things, ETPs are subject to the risks you may face if investing in the components of the ETP, including the risks relating to investing in complex securities (such as futures and swaps) and risks associated with the effects of leveraged investing in geared funds. Investors should be familiar with the diverse characteristics of each ETF, ETN, future, option, swap and any other relevant security type. We have summarized several risk factors (as identified in prospectuses for ETPs and in other sources) and included links so you can conduct further research. Please keep in mind that this is not a complete list of the risks associated with these products and investors are responsible for understanding and familiarizing themselves completely before entering into risk-taking activities. By providing this information, Interactive Brokers (IB) is not offering investment or trading advice regarding ETPs to any customer. Customers (and/or their independent financial advisors) must decide for themselves whether ETPs are an appropriate investment for their portfolios.

An ETP may not be benchmarked to the index it appears to track
"An investor should only consider an investment in a Fund if he or she understands the consequences of seeking exposure to VIX futures contracts. The Funds are benchmarked to the S&P VIX Short-Term Futures Index, an investable index of VIX futures contracts. The Funds are not benchmarked to the VIX Index. The VIX Index is a non-investable index that measures the implied volatility of the S&P 500. For these purposes, "implied volatility" is a measure of the expected volatility (i.e., the rate and magnitude of variations in performance) of the S&P 500 over the next 30 days. The VIX Index does not represent the actual volatility of the S&P 500. The VIX Index is calculated based on the prices of a constantly changing portfolio of S&P 500 put and call options. The Index underlying each Fund consists of short-term VIX futures contracts. As such, the performance of the Index and the Funds can be expected to be very different from the actual volatility of the S&P 500 or the performance of the VIX Index."   [Page 1]
"… your ability to benefit from any rise or fall in the level of the VIX Index is limited. The Index underlying your ETNs is based upon holding a rolling long position in futures on the VIX Index. These futures will not necessarily track the performance of the VIX Index. Your ETNs may not benefit from increases in the level of the VIX Index because such increases will not necessarily cause the level of VIX Index futures to rise. Accordingly, a hypothetical investment that was linked directly to the VIX Index could generate a higher return than your ETNs."   [Page PS-12]
ETPs may not provide a suitable hedge
"Historical correlation trends between the Index and other asset classes may not continue or may reverse, limiting or eliminating any potential diversification or other benefit from owning a Fund."   [Page 20]
Volatility based ETPs are volatile in themselves and are not intended for long term investment
"… investments can be highly volatile and the Funds may experience large losses from buying, selling or holding such investments. ... In addition, gains, if any, may be subject to significant and unexpected reversals. The Funds generally are intended to be used only for short-term investment horizons. As with all investments, an investor in any of the Funds could potentially lose the full principal value of his/her investment, even over periods as short as one day."   [Page 1]
"The ETNs are only suitable for a very short investment horizon. The relationship between the level of the VIX Index and the underlying futures on the VIX Index will begin to break down as the length of an investor’s holding period increases, even within the course of a single Index Business Day. ... The ETNs are not long term substitutes for long or short positions in the futures underlying the VIX Index. ... The long term expected value of your ETNs is zero. If you hold your ETNs as a long term investment, it is likely that you will lose all or a substantial portion of your investment. "   [Page PS-15]
The use of leveraged positions could result in the total loss of an investment
"The Ultra Fund utilizes leverage in seeking to achieve its investment objective and will lose more money in market environments adverse to its respective daily investment objectives than funds that do not employ leverage…
For example, because the Ultra Fund includes a two times (2x) multiplier, a single-day movement in the Index approaching 50% at any point in the day could result in the total loss or almost total loss of an investor’s investment if that movement is contrary to the investment objective of the Fund, even if the Index subsequently moves in an opposite direction, eliminating all or a portion of the movement…
Inverse positions can also result in the total loss of an investor’s investment. For the Inverse Fund, a single-day or intraday increase in the level of the Fund’s benchmark approaching 100% could result in the total loss or almost total loss of an investor’s investment, even if such Fund’s benchmark subsequently moves lower. "   [Page 14]
Possible illiquid markets may exacerbate losses
"Financial Instruments cannot always be liquidated at the desired price. It is difficult to execute a trade at a specific price when there is a relatively small volume of buy and sell orders in a market. A market disruption can also make it difficult to liquidate a position or find a swap counterparty at a reasonable cost. "   [Page 17]
Short covering may intensify losses in volatility-related ETPs
In the event of a sudden market volatility change, many traders with positions in volatility-related products will incur substantial unexpected losses. These losses may cause them to choose to close their positions. The losses may also result in margin deficits and subsequent liquidations of some or all positions. Such closing trades will add to the movement of these products. Since speculative interest in the VIX is at an all-time high, there may be no precedent for what will happen if volatility moves quickly.
The Commodity Futures Trading Commission's (CFTC) weekly Commitments of Traders (COT) report provides a breakdown of the net positions for "non-commercial" (speculative) traders in U.S. futures markets. As of September 2017 CFTC reported VIX speculative net short is at an all-time high.
"Despite the fact that the average daily closing value of the CBOE Volatility Index (VIX) is about 11.5 so far this year, VIX futures and options both had record days for volume and for open interest this month. … VIX futures hit a new record for open interest with more than 673,000 contracts on August 7 (2017), and VIX options reached a new record for open interest with 14,783,380 contracts open on August 15 (2017)."
*As this data is constantly changing, investors in volatility-related products should regularly check for updates.
ETP issuers may redeem shares for cash in the event of extreme moves
"The Intraday Indicative Value on any Index Business Day could be reduced to 20% or less of the prior day’s Closing Indicative Value. If this occurs, we may choose to exercise our right to effect an Event Acceleration of the ETNs for an amount equal to that day’s Closing Indicative Value and you may not receive any of your initial investment."   [Page PS-17]

Allocation of Partial Fills


How are executions allocated when an order receives a partial fill because an insufficient quantity is available to complete the allocation of shares/contracts to sub-accounts?



From time-to-time, one may experience an allocation order which is partially executed and is canceled prior to being completed (i.e. market closes, contract expires, halts due to news, prices move in an unfavorable direction, etc.). In such cases, IB determines which customers (who were originally included in the order group and/or profile) will receive the executed shares/contracts. The methodology used by IB to impartially determine who receives the shares/contacts in the event of a partial fill is described in this article.



Before placing an order CTAs and FAs are given the ability to predetermine the method by which an execution is to be allocated amongst client accounts. They can do so by first creating a group (i.e. ratio/percentage) or profile (i.e. specific amount) wherein a distinct number of shares/contracts are specified per client account (i.e. pre-trade allocation). These amounts can be prearranged based on certain account values including the clients’ Net Liquidation Total, Available Equity, etc., or indicated prior to the order execution using Ratios, Percentages, etc. Each group and/or profile is generally created with the assumption that the order will be executed in full. However, as we will see, this is not always the case. Therefore, we are providing examples that describe and demonstrate the process used to allocate partial executions with pre-defined groups and/or profiles and how the allocations are determined.

Here is the list of allocation methods with brief descriptions about how they work.

·         AvailableEquity
Use sub account’ available equality value as ratio. 

·         NetLiq
Use subaccount’ net liquidation value as ratio

·         EqualQuantity
Same ratio for each account

·         PctChange1:Portion of the allocation logic is in Trader Workstation (the initial calculation of the desired quantities per account).

·         Profile

The ratio is prescribed by the user

·         Inline Profile

The ratio is prescribed by the user.

·         Model1:
Roughly speaking, we use each account NLV in the model as the desired ratio. It is possible to dynamically add (invest) or remove (divest) accounts to/from a model, which can change allocation of the existing orders.




Basic Examples:


CTA/FA has 3-clients with a predefined profile titled “XYZ commodities” for orders of 50 contracts which (upon execution) are allocated as follows:

Account (A) = 25 contracts

Account (B) = 15 contracts

Account (C) = 10 contracts


Example #1:

CTA/FA creates a DAY order to buy 50 Sept 2016 XYZ future contracts and specifies “XYZ commodities” as the predefined allocation profile. Upon transmission at 10 am (ET) the order begins to execute2but in very small portions and over a very long period of time. At 2 pm (ET) the order is canceled prior to being executed in full. As a result, only a portion of the order is filled (i.e., 7 of the 50 contracts are filled or 14%). For each account the system initially allocates by rounding fractional amounts down to whole numbers:


Account (A) = 14% of 25 = 3.5 rounded down to 3

Account (B) = 14% of 15 = 2.1 rounded down to 2

Account (C) = 14% of 10 = 1.4 rounded down to 1


To Summarize:

A: initially receives 3 contracts, which is 3/25 of desired (fill ratio = 0.12)

B: initially receives 2 contracts, which is 2/15 of desired (fill ratio = 0.134)

C: initially receives 1 contract, which is 1/10 of desired (fill ratio = 0.10)


The system then allocates the next (and final) contract to an account with the smallest ratio (i.e. Account C which currently has a ratio of 0.10).

A: final allocation of 3 contracts, which is 3/25 of desired (fill ratio = 0.12)

B: final allocation of 2 contracts, which is 2/15 of desired (fill ratio = 0.134)

C: final allocation of 2 contract, which is 2/10 of desired (fill ratio = 0.20)

The execution(s) received have now been allocated in full.


Example #2:

CTA/FA creates a DAY order to buy 50 Sept 2016 XYZ future contracts and specifies “XYZ commodities” as the predefined allocation profile. Upon transmission at 11 am (ET) the order begins to be filled3 but in very small portions and over a very long period of time. At 1 pm (ET) the order is canceled prior being executed in full. As a result, only a portion of the order is executed (i.e., 5 of the 50 contracts are filled or 10%).For each account, the system initially allocates by rounding fractional amounts down to whole numbers:


Account (A) = 10% of 25 = 2.5 rounded down to 2

Account (B) = 10% of 15 = 1.5 rounded down to 1

Account (C) = 10% of 10 = 1 (no rounding necessary)


To Summarize:

A: initially receives 2 contracts, which is 2/25 of desired (fill ratio = 0.08)

B: initially receives 1 contract, which is 1/15 of desired (fill ratio = 0.067)

C: initially receives 1 contract, which is 1/10 of desired (fill ratio = 0.10)

The system then allocates the next (and final) contract to an account with the smallest ratio (i.e. to Account B which currently has a ratio of 0.067).

A: final allocation of 2 contracts, which is 2/25 of desired (fill ratio = 0.08)

B: final allocation of 2 contracts, which is 2/15 of desired (fill ratio = 0.134)

C: final allocation of 1 contract, which is 1/10 of desired (fill ratio = 0.10)


The execution(s) received have now been allocated in full.

Example #3:

CTA/FA creates a DAY order to buy 50 Sept 2016 XYZ future contracts and specifies “XYZ commodities” as the predefined allocation profile. Upon transmission at 11 am (ET) the order begins to be executed2  but in very small portions and over a very long period of time. At 12 pm (ET) the order is canceled prior to being executed in full. As a result, only a portion of the order is filled (i.e., 3 of the 50 contracts are filled or 6%). Normally the system initially allocates by rounding fractional amounts down to whole numbers, however for a fill size of less than 4 shares/contracts, IB first allocates based on the following random allocation methodology.


In this case, since the fill size is 3, we skip the rounding fractional amounts down.


For the first share/contract, all A, B and C have the same initial fill ratio and fill quantity, so we randomly pick an account and allocate this share/contract. The system randomly chose account A for allocation of the first share/contract.


To Summarize3:

A: initially receives 1 contract, which is 1/25 of desired (fill ratio = 0.04)

B: initially receives 0 contracts, which is 0/15 of desired (fill ratio = 0.00)

C: initially receives 0 contracts, which is 0/10 of desired (fill ratio = 0.00)


Next, the system will perform a random allocation amongst the remaining accounts (in this case accounts B & C, each with an equal probability) to determine who will receive the next share/contract.


The system randomly chose account B for allocation of the second share/contract.

A: 1 contract, which is 1/25 of desired (fill ratio = 0.04)

B: 1 contract, which is 1/15 of desired (fill ratio = 0.067)

C: 0 contracts, which is 0/10 of desired (fill ratio = 0.00)


The system then allocates the final [3] share/contract to an account(s) with the smallest ratio (i.e. Account C which currently has a ratio of 0.00).

A: final allocation of 1 contract, which is 1/25 of desired (fill ratio = 0.04)

B: final allocation of 1 contract, which is 1/15 of desired (fill ratio = 0.067)

C: final allocation of 1 contract, which is 1/10 of desired (fill ratio = 0.10)


The execution(s) received have now been allocated in full.


Available allocation Flags

Besides the allocation methods above, user can choose the following flags, which also influence the allocation:

·         Strict per-account allocation.
For the initially submitted order if one or more subaccounts are rejected by the credit checking, we reject the whole order.

·         “Close positions first”1.This is the default handling mode for all orders which close a position (whether or not they are also opening position on the other side or not). The calculation are slightly different and ensure that we do not start opening position for one account if another account still has a position to close, except in few more complex cases.

Other factor affects allocations:

1)      Mutual Fund: the allocation has two steps. The first execution report is received before market open. We allocate based onMonetaryValue for buy order and MonetaryValueShares for sell order. Later, when second execution report which has the NetAssetValue comes, we do the final allocation based on first allocation report.

2)      Allocate in Lot Size: if a user chooses (thru account config) to prefer whole-lot allocations for stocks, the calculations are more complex and will be described in the next version of this document.

3)      Combo allocation1: we allocate combo trades as a unit, resulting in slightly different calculations.

4)      Long/short split1: applied to orders for stocks, warrants or structured products. When allocating long sell orders, we only allocate to accounts which have long position: resulting in calculations being more complex.

5)      For non-guaranteed smart combo: we do allocation by each leg instead of combo.

6)      In case of trade bust or correction1: the allocations are adjusted using more complex logic.

7)      Account exclusion1: Some subaccounts could be excluded from allocation for the following reasons, no trading permission, employee restriction, broker restriction, RejectIfOpening, prop account restrictions, dynamic size violation, MoneyMarketRules restriction for mutual fund. We do not allocate to excluded accountsand we cancel the order after other accounts are filled. In case of partial restriction (e.g. account is permitted to close but not to open, or account has enough excess liquidity only for a portion of the desired position).




1.        Details of these calculations will be included in the next revision of this document.

2.        To continue observing margin in each account on a real-time basis, IB allocates each trade immediately (behind the scenes) however from the CTA and/or FA (or client’s) point of view, the final distribution of the execution at an average price typically occurs when the trade is executed in full, is canceled or at the end of day (whichever happens first).

3.       If no account has a ratio greater than 1.0 or multiple accounts are tied in the final step (i.e. ratio = 0.00), the first step is skipped and allocation of the first share/contract is decided via step two (i.e. random allocation).


Additional Information Regarding the Use of Stop Orders

U.S. equity markets occasionally experience periods of extraordinary volatility and price dislocation. Sometimes these occurrences are prolonged and at other times they are of very short duration. Stop orders may play a role in contributing to downward price pressure and market volatility and may result in executions at prices very far from the trigger price. 

Investors may use stop sell orders to help protect a profit position in the event the price of a stock declines or to limit a loss. In addition, investors with a short position may use stop buy orders to help limit losses in the event of price increases. However, because stop orders, once triggered, become market orders, investors immediately face the same risks inherent with market orders – particularly during volatile market conditions when orders may be executed at prices materially above or below expected prices.
While stop orders may be a useful tool for investors to help monitor the price of their positions, stop orders are not without potential risks.  If you choose to trade using stop orders, please keep the following information in mind:
·         Stop prices are not guaranteed execution prices. A “stop order” becomes a “market order” when the “stop price” is reached and the resulting order is required to be executed fully and promptly at the current market price. Therefore, the price at which a stop order ultimately is executed may be very different from the investor’s “stop price.” Accordingly, while a customer may receive a prompt execution of a stop order that becomes a market order, during volatile market conditions, the execution price may be significantly different from the stop price, if the market is moving rapidly.
·         Stop orders may be triggered by a short-lived, dramatic price change. During periods of volatile market conditions, the price of a stock can move significantly in a short period of time and trigger an execution of a stop order (and the stock may later resume trading at its prior price level). Investors should understand that if their stop order is triggered under these circumstances, their order may be filled at an undesirable price, and the price may subsequently stabilize during the same trading day.
·         Sell stop orders may exacerbate price declines during times of extreme volatility. The activation of sell stop orders may add downward price pressure on a security. If triggered during a precipitous price decline, a sell stop order also is more likely to result in an execution well below the stop price.
·         Placing a “limit price” on a stop order may help manage some of these risks. A stop order with a “limit price” (a “stop limit” order) becomes a “limit order” when the stock reaches or exceeds the “stop price.” A “limit order” is an order to buy or sell a security for an amount no worse than a specific price (i.e., the “limit price”). By using a stop limit order instead of a regular stop order, a customer will receive additional certainty with respect to the price the customer receives for the stock. However, investors also should be aware that, because a sell order cannot be filled at a price that is lower (or a buy order for a price that is higher) than the limit price selected, there is the possibility that the order will not be filled at all. Customers should consider using limit orders in cases where they prioritize achieving a desired target price more than receiving an immediate execution irrespective of price.
·         The risks inherent in stop orders may be higher during illiquid market hours or around the open and close when markets may be more volatile. This may be of heightened importance for illiquid stocks, which may become even harder to sell at the then current price level and may experience added price dislocation during times of extraordinary market volatility. Customers should consider restricting the time of day during which a stop order may be triggered to prevent stop orders from activating during illiquid market hours or around the open and close when markets may be more volatile, and consider using other order types during these periods.
·         In light of the risks inherent in using stop orders, customers should carefully consider using other order types that may also be consistent with their trading needs.
