The prop firm am using requires to put stop loss immediately before placing a trade but my ex4 ea don have sl so I need extra file

Someone gave me ea but only ex4 file my issue is that the ea don’t have stop loss option so my question is if you can creat only stop loss file that can automatically place stop loss in any trade it sees in mt4 once ea or open trade in the mt4 the software will automatically place stop loss immediately based on the pip I set in the stop loss software
