Backtesting 99% model quality

 

Why this 99% quality need for EA backtest.

An EA that work by Original  mt4 history data download backtesting not work in real tick history data backtesting.

What the hell is going on.

So we will need to buy always this real tick history .

Very disappointed.

 

Very often people doesn't know differences between testing modes and systems that they are backtesting.

A system that works with only prices and indicator's values from last closed candles, and do not use functions based on Ask/Bid prices can be backtested with only open prices or control points, but people always want Real tick backtests, for the only reason that there are a lot of ignorance in trading world.

Usually this kind of people are the same that have a lot of other convictions... like becoming rich using a night scalper... so funny
