Quote from yip1997:
I shouldn't call it a hedge to the vertical itself. I looked at the overall greeks, and decided to adjust it with the outlook that rut unable to break new high (around 801). It was an adjustment, not a delta neutral hedge. My b.e. point was 805. If RUT run beyond 801, I would buy additional long calls (or another call calendar) to hedge again (I had some Mar and June calls already).
You can say that it was an independent trade. I also had a outlook that rut would settle between 780 and 800 (very likely a little bit below 790), and the calendar itself had a be point at around 780 and 800.
It is the first month I tried a new strategy based on the risk-based margin (though I am still trading under reg-T). I expect this strategy will give me around 3 times leverage under risk-based margin. With haircut (or new risk-based margin), my return would be around 9%.
