Hi, need simple line of code - auto SL at zero

Hi, is it posilble to code, one simple thing, i just need for ex. then pirce comes up to proftable side about 20-30 pips stoploos sets automaticly on zero, in that price level was opened order. I know abaout the trailing stop, but i will use this at higher level of profit, so i just need to put that kind of line into my ea thats set stopl los at zero automaticly than range reaches my wanted level.

Thank you.

i have looked much of them, but most are scripts, but i need to attach it my ea, i also need to attach lot size incresmet code, if wins stays the same, i loses incremes by 0.01. Is it posible?

the problem is that all thees ea's or scripts are adding already on working screen, but i cant add second ea at the same time, i just need to inject those codes to allredy working ea
