I do not know of any Not sure what you mean by FORCE IT though. Schwab calculates off of the last trade but if there is no volume will use the previous close or the bid. If there is a trade at the Ask early in the day and then nothing the rest of the day that is what Schwab uses for the gains/loss for the day. Not always an accurate view if the bid/ask have dropped during the day. I usually just watch the bid and calculate my contracts by it to come up with what I think my account value should be at. The last trade is the most accurate as long as there is volume as you can usually catch a similar trade. The bid is probably the better to use but I am not sure how many brokerages are forced to use it as a value, if that is what you meant? I would not worry about gains and losses unless you are looking for specific stop loss triggers or profit triggers. If that is the case then I would pay attention only to the bid, JMHO though. Enjoy the Day Bull! :^)
