Writing own trailing stop & Stop Loss script

New comment
 

I found a few good "script order" that are helpful but none them had auto-trailing stop, and 0 in stop loss is the price of entry. What up with that. Null does not work. 

I post this topic in hope that someone guide me or send me to an article on how to create an auto-trailing & set stop loss to "null", onto an existing script, for my own personal use only. 

 

I use an ATR trailing stop. here's my code, enjoy!


I call this function via:

void onTick(){

ATRTrailingStop(ATRValue,AskStopLoss,_MagicNumber);

}


and pass on ATR value etc..
