If you havent done so the last few days, go into acct management and clk on Activity Statements - not the legacy version. See msg at top.
So that we don't kill IB's account management system with our 94,000 hits (all but 832 of ETs active members are IB customers, right?), the message I got was: "Warning: Some of the cost basis calculations displayed on your 2007 annual statement are incorrect and a new annual statement will be generated for US customers by 03/10/2008 and for non-US customers by 03/28/2008. The MTM & FIFO P/L calculations displayed are correct even for those transactions with an incorrect cost basis."
i'm guessing for daytraders, this wouldn't matter...right? just longer term people who add / subtract around a core position over a longer period of time? just checking, and i very well could be wrong.
