Information regarding high precision forex quotes

概観: 

Clients wishing to see forex (IDEALPRO) market data in a more detailed way can now control the order book display mode via the Global Configuration. In order to access this feature you must use TWS release 944.2b or higher. The display mode selection allows the order book to be viewed either as:

  • Rounded prices (default): market data is rounded out to the next 0.5 pip. This is identical to the current display functionality for the IB trading platforms. This setting provides a more stable visible quote and a larger ‘top-of-book’ size since it includes the available size at multiple price levels up to the rounded price.
  • Unrounded prices: market data is visible in 0.1 pip increments. This allows you to see prices in a more granular fashion, but the displayed values will change more rapidly and the sizes for the top-of-book may appear to be smaller.

It is important to understand that either display mode accesses the same IDEALPRO order book. Order submission will still be in 0.5 pip increments and orders submitted in either display mode will execute in exactly the same way. As in the past (and currently), in cases where the order book has prices at better than your order’s limit price, you will receive the full price improvement.

Determining Tick Value

Financial instruments are subject to minimum price changes or increments which are commonly referred to as ticks. Tick values vary by instrument and are determined by the listing exchange. IB provides this information directly from the Contract Search tool on the website or via the Trader Workstation (TWS). To access from TWS, enter a symbol on the quote line, right click and from the drop-down window select the Contract Info and then Details menu options.  The contract specifications window for the instrument will then be displayed (Exhibit 1).

To determine the notional value of a tick, multiple the tick increment by the contract trade unit or multiplier.  As illustrated in the example below, the LIFFE Mini Silver futures contact has a tick value or minimum increment of .001 which, when multiplied by the contract multiplier of 1,000 ounces, results in a minimum tick value of $1.00 per contract.  Accordingly, every tick change up or down results in a profit or loss of $1.00 per LIFFE Mini Silver futures contract.
