Option values reported

It appears that C2 account values are reported using the “last trade” rather than “bid-ask” for options. Any way that can be changed? I do spreads, and as they move out or in to the money, they are less actively traded, so the Last is often quite different from the bid-ask, resulting in reported account value to be significantly different from reality.

I encountered something similar…hope the IT staff resolves this soon
also strange, why contracts as they move in the money are not triggered by my buyers…
not sure but I think C2 needs to review the way/rules they calculate the value of our option trades
