Blew through stop...

[Delta007]

Backtesting a large basket of stocks. I have a set .75 stop loss as shown below based on 1minute bars. On 7/19/12 at 11:18 ticker APC dropped about 3.5pts in 4minutes. It blew right through my stop. Is there any way to avoid this or handle it in a better way? Also I figured in backtesting it would not bypass the stop like it would live?

for(int i = 0; i < 280; i++)
if ((BarsInProgress == i + 280)&& (Position.MarketPosition == MarketPosition.Long)
&& Closes[i+280][0] < Position.AvgPrice - .75)//StopLoss
{
ExitLong(i+280, 200 , "StopLoss"+i, "EnterLong"+i);
}

Delta007, that's just a market order you issue when triggered - so the bar after the condition to do so became true in backtesting. So that outcome would be expected.
