I've developed MIX core which analyze C-O & C-C(-1) values. Then I've added feature for simulation of real TrendMedium using for RT (I have some extra package for EOD and usesing it for www.ProfitFromStocks.com) In other words what the package doing in the walk test mode. 1. Load data before some days market open. 2. Calc system for this date range. 3. Save system 4. Load data with the NEXT trading day. 5. Calc signals and then keep it (no recalc system during trading day). 6. Do it for some last days and see how it works. I've developed it for best params optimization... Regards, Eugene Labunsky.
