Does anyone know if there is one of those add-on optimizers for TradeStation 2Ki that will, in addition to the "normal" optimizing, will also optimize on being profitable every day? I do not want maximum return, I want low stddev around the mean. For example, I want an optimizer that will optimize on inputs, but then, penalize those parameters that made money some days and not othes. So I would prefer parameter P1 P2 P3 that gave the following P/L days: + 120 + 165 +25 -10 ==== +300 To P1 P2 P3 that gave the following P/L for the same days: +350 -245 +442 -200 === +347 Thanks, nitro
