Some said every tick based on real ticks is the most accurate data collection rather than every tick.
By that, I tested some EA that I purchased before, and some stated they will have massive profit, however their report was based on every tick
After that, I used every tick based on real ticks to run the back-test. The result was not the thing I expected.
So, can we conclude that, using Every tick in their report was meaningless, as they cannot show the actual performance?
I am still a beginner of EA, so please tell me if I ask something dumb.
