I have a one-lot (yeah, I know big spender) Bearish Butterfly on. I opened the trade on 12/29 when RUT was 1358.82 with a 1290 1340 1390 Feb 28 fly. On 1/5 I added a 1310 1360 1410. Since then the Rut has bounced around and I haven't added anything else. According to Optionnet I should be up $1400 now. However, when I check midprices on IB, TOS, and E*Trade the profit is around $440. What gives?
Are you sure you've modeled them the same way in both TOS and ONE? I just modelled the trade in both and when I look at them on my machine I get the same answers for both. Right now in TOS I see a PnL of $1,163 (commissions included). In ONE I see a PnL of $1,159. (On 03-Feb at 7:25 PST) Neil Gillis
