I like. I have the following on: Dec 02 119 (sold today) vs the Dec16 126 (bought long ago) such that the Dec02 119 notional = Dec16 126 delta. This is about 1% of my account by your calculations.
On what timeframe is the data you're using as an input - are you using daily data? Sounds like a fun acct to run. GL.
Completely flat and up 2% since the new format. PTT (peak to trough) draw-down was 0.3% marked. I'll post weekly IB performance stats.
good trading. being fundamentally short gamma and still making money last week and today is impressive.
Those were a good trade. Thoughts on this? I did this for 2% risk (based on your calculations) SPY Dec 110 134 call fly for 6.7
