[amibroker] Scale Out Question

["jjj_98" <jjj_98@xxxxxxxxx>]

Hi,

Trying to scale out of a position in my code and used the code from 
one of the articles on the AB website.  What is happening is that the 
program does not recognize the profit targets or trailing stops that 
have been set up in the code.  At one point it was recognizing it, 
but not correctly and when it scaled out it scaled out 100% rather 
than 50%.

I've spent a few hours trying to make this work.  I'd really 
appreciate it if anyone could take a look at the portion of the code 
in question below and let me know if they see any obvious problems.  
Yes, I have defined TrailingStop and FirstProfitTarget parameters.

thx,

PriceatBuy = 0;
PriceatShort = 0;
HighSinceBuy = 0;
LowSinceShort = 0;
Exit = 0;

for( i = 0; i < BarCount; i++)
{
	if(PriceAtBuy == 0 AND Buy[i])
	{
		PriceAtBuy = BuyPrice[i];
	}
	if(PriceAtBuy > 0)
	{
		HighSinceBuy = Max(High[i] , HighSinceBuy);
		if(Exit == 0 AND High[i] >= (FirstProfitTarget + 
PriceAtBuy)) 
		{
		// first profit target hit - Scale Out
		Exit = 1;
		Buy[i] = sigScaleOut;
		SellPrice[i] = FirstProfitTarget + PriceAtBuy;	
	
		}
		if(Low[i] <= (HighSinceBuy - TrailingStop))
		{
		// trailing stop hit - exit
		Exit = 2;
		SellPrice[i] = (HighSinceBuy - TrailingStop);
		}
		if(Exit == 2)
		{
		Buy[i] = 0;
		Exit = 0;
		PriceAtBuy = 0;
		HighSinceBuy = 0;
		}
	}
	
	if(PriceatShort == 0 AND Short[i])
	{
		PriceatShort = ShortPrice[i];
	}
	if(PriceatShort > 0)
	{	
		LowSinceShort = Min(Low[i] , LowSinceShort);
		if(Exit == 0 AND Low[i] <= (PriceatShort - 
FirstProfitTarget)) 
		{
		// first profit target hit - Scale Out
		Exit = 1;
		Short[i] = sigScaleOut;
		}
		if(High[i] >= (LowSinceShort + TrailingStop))
		{
		// trailing stop hit - exit
		Exit = 2;
		BuyPrice[i] = (LowSinceShort + TrailingStop);
		}
		if(Exit == 2)
		{
		Short[i] = 0;
		Exit = 0;
		PriceatShort = 0;
		LowSinceShort = 0;
		}

	}

}
SetPositionSize(50,spsPercentOfPosition*((Buy == sigScaleOut)+(Short 
== sigScaleOut)));
//scale out of 50% of position
