Modeling Quality does not means EA quality it means broker graph M1 history graph quality
tick simulation is not realistic enough, so if u do it via tick simulation it doesnt represent the work on real conditions. and when u use 1M data it can always misrepresent the entry and exit points. so you have to try the EA on real time data or on real tick history.
btw the new feature of MT5, seems enough to solve this (real tick history data use on tester), so in the near future we can trust backtests about that it does really represent the real conditions.
on the other hand there is a serious question: is the real conditions of market, stable enough to represent the future conditions?
that is the issue, and always will be..
so with the current features of MetaTrader i think it is (%90) not good enough.
The real question here is:
90% Backtest data,
Good enough, For what ?
Marco, you should create a topic to explain your view about the backtester.
It will be more constructive and positive that always questioning people.
I use back-testing in only to get a general idea about will I consider there is a hope in this EA ? But it is not final. Forward testing is essential.
Also use it to check the visual mode to know if my EA works exactly as I must to do or to reveal others EAs ideas.
So, even if I got 90% modelling quality, it is not enough to use it on live account.
I learned over the years, that if someone is on collision course, nothing can or will stop them from achieving total destruction.
