these are two videos from projectoption where mr. Butler evaluates the results of selling iron condors and put spreads every trading day from 2006 to 2017 on the spy etf: mr. Butler's work is magnificent. his results and conclusions are perfectly supported by the evidence. if i wanted to carry out similar analysis, ¿are there any platforms that allow for backtesting of rules based strategies on options? i would like to evaluate the returns of similar strategies on individual stocks, other etf's, as well as some selling and buying strategies that followed simple rules (only buy - sell when previous close > simple moving average, etc). thanks.
