Lately I've been making money selling verticals. I think by nature I want to be a net seller of options (i think vol is overpriced a good % of the time) but i don't have the cajones or the deep pockets that it takes to sell nakeds. i like the defined risk reward of selling verticals. i'd do an iron condor here and there as well (since its really just selling a call vert and a put vert).
Dual replication -- intermarket [index1/index2] vanilla fly deltas into exotic NTs with switch-hedge [futures time spreads]. Short lookbacks; lookback strangles.
