I am looking at ways to automate my mt4 trading. I have a strategy that when back tested on TV is working. It is built on pine script and uses the atr to set a stop loss and first take profit. When first tp is  hit it removes 50% of my position resets the sl at entry and then exists at atr cross.

This is all coded in pinescript but uncertain if it can be utilised easily on MT4. I have a demo account and the brooker allows capitalise ai which I plan to use but is this possible can I set multi tp and trailing stop losses or what is the best way to deal with it
