If you are relying on the Gain/Loss and or Cash Flow (or Y axis of the P/L Graph) from OptionVue, you may want to consider a 2nd opinion of the values being reported. A simple check is to SUM the NET transactions for a given TradeID/code/ R field, which if added to the current Position value should be accurate for a Gain/Loss (P&L)check. I observed a case (Ticket submitted yesterday), where a closing trade, adjusted the Cash Flow value by the "Original Price" instead of the Market price. (Have only observed this for the Jun 20th RTT RUT PUT sale so far). -- I have noticed NO errors in the NET transaction amount in the OV log! So, to say differently, the Transaction Log is good, but what is reported by OV is sometimes not so good.
