But I am interested only in 10 of them. It's possible, but complicated and takes a long time to complete since you effectively have to sort at ever symbol iteration. It would be *much* easier to run the scan, sort by hand and then just add the top 10 to a watchlist. > 4) Can I add custom column to a backtest or optimization result window?

However, I believe that your custom columns would only be sorted relative to each other, not to the standard columns (not sure, haven't tried yet). > 5) Can I save the backtest optimization result to a csv file from afl?

One mouse click would create 3 output csv files. Probably do-able. But, this would likely better be done via a separate JScript file using Ole Autmation: http://www.amibroker.com/guide/objects.html Else, using BatMan for batch processing, found in Files section of this group. > 6) is there available detailed report about backtesting saying: XXX was > nominated but we did not enter the trade because of not enough capital.
