Every evening after the mkt closes I go through my IB account page and reconcile my trades and verify my account values etc. Several times I have had a problem where the numbers are changing as I am trying to do my accounting. For example .. options that have been closed for hours change their closing price. tonight the puts and calls all changed. My account changed also but the change did not match the change in the TWS. My account changed to some values somewhere between the TWS posted and the closes that were posted 15 minutes earlier on my account page. I logged out and back in and all the #s changed again. So I started recalculating and then they changed again.. to some entirely different values. Has any one else had this problem?? This has never happened to me on any closed positions just open SSF and option positions. This is driving me nuts.
