Every tick issue

[WorldlFxTrading]

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 only.

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.

yes "real ticks" is the best way to backtest an EA because it holds the real spreads of the broker in real time
