In general any generated EA will be slower that the same strategy if you are able to carefully code it manually. This is because the generated EA is full with useless code. My EA builder is not so clever to only include the code that is needed and to optimize it in the best way, so you always end up with bloated slow code. But it should not be too slow... like waiting for hours to backtest one day. It is important what blocks are you running on every tick. Try to connect them in such a way, so the slowest block are running more rarely. Of course, you can't always say which blocks are slower than others... even I can't tell that without testing them. But maybe you are using some custom indicator - maybe this indicator is poorly written and it is too slow. Put that indicator in few blocks and the time stops 🙂
