I did some more research on this.
The issue is related to how C2 marks-to-market the value of open options positions (and your strategy has a LOT of open options positions). The summary of the problem is this:
When the markets close, C2 uses “last” prices to value these positions (because bid/asks become bogus); but during market-open hours we’ll use the bid/ask (typically more favorable).
This can cause fluctuating results in cases where options are relatively illiquid and the “last” actual trade price is very different from the more recent bids and asks.
This is an issue we’ve never really found a satisfactory solution for. I’m going to try to see if I can make the logic here a bit more supple, so that you don’t see these valuation oscillations (as often?).
I hope you will be able to stick it out and, for now, ask your subscribers to be aware that this is a marking-to-market issue, not related to your closed-trade performance. In the meantime, I’ll see if I can make C2 handle these kind of strategies a bit better.
If you see really obviously bad marked-to-market valuations, do me a favor - just send an email to email@example.com with the relevant screenshot and also the date and time (in ET) that you see the weird valuation.
And of course I will understand if you just decide that C2 isn’t right for you, given the type of startegy you are running. If that’s the case, just let me customer service colleagues know you’d like a refund and we’ll respect your request. I hope you’ll stick it out a bit longer to see if we can make the options-valuation logic a bit better.
