[amibroker] How signals are handled when cash is maxed out?

["ezbentley" <ezbentley@xxxxxxxxx>]

I am testing a strategy on a basket of stocks. The strategy always exits n bars after entry. I 
found one interesting thing. When a buy signal is generated on a particular day on which 
previous other stock trades should be exited, the following two difference pieces of code 
will behave differently:

1. When cash is maxed out and Buy and Sell happen on the same bar,
this code will sell positions and use the proceeds to enter new positions:
BuyPrice = O;
SellPrice = O;
Buy = Ref(Condition, -1);
Buy = ExRemSpan(Buy, Delay);
Sell = Ref(Buy, -Delay);

2. When cash is maxed out and Buy and Sell happen on the same bar,
this code will sell positions and skip the new positions:
BuyPrice = O;
SellPrice = O;
Buy = Ref(Condition, -1);
Buy = ExRemSpan(Buy, Delay);
Sell = 0;

priceatbuy = 0;
for(i = 0; i < BarCount; i++) {
	if (priceatbuy == 0 AND Buy[i]) {
		priceatbuy = BuyPrice[i];
	}
	if (priceatbuy > 0 AND Buy[i - Delay]) {
		SellPrice[i] = O[i];
		Sell[i] = 5; // n-bar exit code
		priceatbuy = 0;
	}
}

Changing the BuyPrice and/or SellPrice to Open or Close does not change the behavior. 
Does anyone know how to make code 2 behave the same as code 1? I have to use the for 
loop approach for scaling out.

Thanks in advanced,
