Average trade prices may be susceptible to reporting error on the Trader Workstation, particularly in situations where a corporate action or position transfer takes place.  While this information is intended for advisory purposes only and such errors have no impact upon the account equity or any ultimate tax obligation of the account holder, this information is adjustable by the account holder.  To adjust the average cost of a particular security, open the Account Window within the Trader Workstation and scroll down to the Portfolio section. Select the asset in question from the Portfolio section and right click on it to display the drop-down window and the Adjust Average Price menu option. Enter the desired average price into the dialog box and click OK to update the Trader Workstation view.
