Stop-Loss Techniques

[Sinan Atahan <sinan@xxxxxxxxxxxxx>]

I am running a few trend following systems. My channel breakout system 
needs a little bit of improvement on the exit strategy.

Here is what i use:

	if marketposition(0)=1 then begin
		MMLngStp=EntryPrice(0)- StopLoss points;
		if mashrt crosses under malng then begin
			exitlong("EL-MAXO") on the open;
			if LastBarOnChart then FileAppend(FilePath,ElDateToString(Date)+ "," + 
CurrPairOut+",Sell,"+CashStr+",At Market,"+NewLine);
		end
		else begin
			if (ExitC2=false) then begin
				if LastBarOnChart then FileAppend(FilePath,ElDateToString(Date)+ "," + 
CurrPairOut+",Sell,"+ 
CashStr+","+NumToStr(MMLngStp,DecPlc)+",Stop-Protect,Cash," +Delivery+ 
NewLine);
			end
			else begin
				ExitLong("EL-SL") at EXPrcL stop;
				if EXPrcL<MMLngStp then ExPrcL=MMLngStp;
				if LastBarOnChart then FileAppend(FilePath, ElDateToString(Date)+ "," + 
CurrPairOut+",Sell,"+ 
CashStr+","+NumToStr(ExPrcL,DecPlc)+",Stop-Protect,Cash," +Delivery+ NewLine);	
			end;
		end;
	end;

My stops are usually ineffective and most profitable trades are closed on 
the very lows or even in losses.. I would appreciate if you could give me 
some pointers. Or for research where should i look at..

Thanks in advance..
