If you wish to remove the yellow arrows which denote news on your charts, follow the steps listed below:
From the Chart window, go to the Configure menu and select Settings. From the Trader Workstation Configuration window, find the section titled "Highlight on chart". If you have the yellow arrows, then the box titled "News" will have a check mark in it. Click on the box to remove the check. Once the check is removed and the box is empty, click the Apply button, and then click the OK button. The yellow arrows should no longer appear.
