Add functions to expert

Good day I need help with the modification of my Expert advisor.

The EA uses the Martingale system and trailing stop e.g opening a buy or sell trade, it starts by opening a 0,1 lot if the market goes the opposite direction, it opens a 0,02 and raises the take profit, then 0,02 again and so on until 0,38. I want to place the stop loss around 100 pips or so stop loss after the 0,38 trade to close everything if it touches the stop loss. This results in the account being blown because it does not have any limits. It opens a trade for too long until the balance gets exhausted. If the EA had a stop loss at some point it would stop and restart instead of continuing until the account runs out of funds.
