I didn't get a chance to look at your code yet. But here's a generic loop
that might be useful
Buy = Short = Bought = Shorted = BuyopenPrice = Shortopenprice = 0;
Buy[1] = Bought[1] = 1; //Initialize 1st bar to a Buy
for (i = 2; i < BarCount-1; i++)
{
//Continue these variables across the loop
Bought[i] = Bought[i-1];
Shorted[i] = Shorted[i-1];
BuyOpenPrice[i] = BuyOpenPrice[i-1];
ShortOpenPrice[i] = ShortOpenPrice[i-1];
//Remove intermediate signals
if (Short[i] AND Shorted[i-1])
{Short[i] = 0;
}
if (Buy[i] AND Bought[i-1])
{Buy[i] = 0;
}
//Test for Buy exit
if (Bought[i-1])
{
Buystopprice[i] = BuyOpenPrice[i] - XXX; //Stop value code here
if (C[i] < BuyStopprice[i] )
{
Short[i] = Shorted[i] = 1; //This is reversal system (New short when Long
closes) You may not want this
ShortOpenPrice[i] = C[i];
Bought[i] = 0;
}
}
//Test for Short exit
if (Shorted[i-1])
{
ShortStopPrice[i] = ShortOpenPrice[i] + XXX; //Stop value code here
if (C[i] > ShortStopprice[i] )
{
Buy[i] = Bought[i] = 1;
BuyOpenPrice[i] = C[i];
Shorted[i] = 0;
}
}
}
