Opened: IWM February 25th 197/300 Short Strangle... for a 3.27 credit.
Comments: Here, just adding in a little IWM in the weeklies around 45 days until expiry while I wait for the March monthly to shorten in duration to do other stuff.
3.27 on buying power effect of 26.15; 12.5% ROC as a function of buying power effect (on margin); 6.3% ROC at 50% max.
