You might want to add in some settings, especially the initital equity
and trades size. your settings in AA window could be a problem if they
do not reflect actual trade conditions.
here is a sample of what I use for various type of testing
SetFormulaName("LastWeek"); //name in backtest report
SetBarsRequired(4000,1); //needed line - do not remove
SetTradeDelays( 1, 1, 1, 1 ); //open & close trades delay
SetOption( "initialequity", 20000 ); //initial capital
PositionSize = 4000; //trade size
SetOption( "MaxOpenPositions", 10 ); //max trades open
SetOption( "PriceBoundChecking", 1 ); //trade within days bar
SetOption( "CommissionMode", 2 ); //brokerage 32.95 up to $30 trade
SetOption( "CommissionAmount", 32.95 ); //brokerage amount
PositionScore = 100/C; //backtest lower price stocks first
BuyPrice=H; //buy at days high price
SellPrice=L; //sell at days low price
