Ask manual confirmation function under ea settings

I check that box, i load the E.A. it asks for my confirmation when I first load the ea. I click “x” the box. the ea doesn’t trade which is what i want it to do. JUST FOR THAT TRADE THOUGH. I am expecting the ea to automatically trade on the next signal because I went back to uncheck that “ask manual confirmation”. A signal arrives, but the ea is not trading. Any suggestions?? could this be an error with the setup of my ea, or what. I just want the ea to trade on a fresh signal when i load it on my chart simple.
