I'm fed up by all those EAs that store the best trading times (but making sure there are also a few losses there and there to make it realistic) inside their EX4 or EX5 so that they can show amazing backtests

how to spot such EAs on MQL5 :

1) first the EA compiled size is very high (> 500kb)
2) it trades on open prices (not always the case)
3) it only trades on main Assets. It doesn't show anything when backtesting on exotic pairs or on other assets like stocks and indices
4) it shows incredible returns
5) signals are always a few days old : signal crashes, get a new one and start again

the way to do such EA is very easy. First you make an algorithm that detects reversals, with a zig zag for example, then you store the date of each trade or the number of bars since the beginning of the month.

then you open trades and let the internal strategy to take care of the trades. most of the trades will be winners that way
you need a strategy like a martingale or so, so that people can compare the backtest (which is real only from compile time) and the real trades. The trades the EA takes are FAKE, or a lesser algorithm. They never meet the same returns as shown in the BT

MQL5 is PLAGUED with such EAs
example :
https://www.mql5.com/en/market/product/111900
-size = 1.36 MB (!!)
-only trade main pairs and not stocks or indices
-shows incredible returns
-signal is recent

you got 4 points on 5 for the scam EA, so my guess is that it is a scam EA
