Don't need a for loop to backtest, Monty -- often best to just check for a fixed period so you can page thru the charts with the the cursor sitting on that day. For example, just substitute every 0 with day in Richard's BBB scan to give
----------------------
//BBB Scan by Richard Estes with backtest
output = "bbb.lst";
integer day;
day:= -60; // Set to 0 for no backtest
if Close(day)-Close(day-5)>.05*Close(day-5) and
Vol(day) > MovAvg(day,63,vol) and
Close(day)>.85*Max(day,day-250,cl) then
println symbol,",",close(day):8:3,",", 100*(max(0,day,cl)-close(day))/close(day):6:1,",", 100*(close(0)-close(day))/close(day):6:1;
endif;
