The Statement checking screen allows you to easily check historical statements, as far back as your data allows.
This screen will show the Long option value and Short option value of any open option positions you have on the statement date. The statement date can be as far back as your current data allows, so that you can go back and re-check older statements should the need arise.
For options trades, you are shown option premium credited or debited to your account on the date of the statement.
There is also the choice to see the fees applicable to futures only, options only or all fees charged to your account on the statement date for both futures and options.
