A simple to follow journal of vanilla equity and equity index short combo to iron butterfly conversions; short gamma/vega and long theta at neutral delta. Conforms to my basic tenet to sell downside and buy upside gamma curvature. Ticker selection is done in bloomberg and a proprietary model in which the primary logic datamines for a small initial gamma/theta value. The initial position will consist of a short downside gamma combo[straddle] traded into the weekend decay -- either on Thursday's close or Friday's opening rotation. The initial short gamma/vega combo will be converted to a short iron fly[synthetic long call or long put fly] when/if certain conditions are met; a flattening of the vol-smile[wing vol compression], opportunity gains from an strip-vol decline, sufficient decay, or simply an arbitrary time limit or delta position incurred on the short body strike.
