Does tick story fix that 4gb limitation on backtests? I remember I was using birt's method and not been able to test all the years of data consecutively was the only downside.

i use BACKTEST but i don't like it because it shows me incredible results of my strategy . it's better to use it for watching how indicators moves .

Backtesing proves several important points. One of the most important would be that humans fail to be consistent. We may have a system which works great for us in back test. Yet, in live our results never translate. In almost 100% of the cases it is because we gain bais to a certain position. Which in reality abandons the system which we are back testing. Many of us use 'rules' just as we input them into indicators or EA's [If this happens, then do this] Yet in live it is very rare to do the same. All in all, to make great amount of money in forex. You must trade like a robot. That is with no BIAS, or emotion towards any direction.

Hi, I developed over 500 EAs as software engeneer, for free for amateurs (a 95%) and for professionals (very few... and not in mql4)

My conclusion is simple, don't trust backtesting!

...a part it's only an amateur game, you can't do it in professional systems

Backtest is very usefull to check if what you developped works as it is supposed to do (entry, exist, sl, tp, loop....) in order to avoid some bad surprise in live.

Even if on MT4 you could get an easily 100% quality model, to be sussessfull while you backtest the past doesn't mean you will make profit in the future.

do you again believe in the 10 minutes money?

the multinationals spends every year bilions and bilions in analysts, engineers, full time employers, and you in ten minutes make the money

of course... you do the backtesting!

Backtest with real tick data then....real tick data is just the same as a live market. The velocity of the price, the exact moment of price surging up and down and the the way the tick behaves are all recorded in a real tick data. Whomever said otherwise doesn't know what they are talking about/have limited knowledge.

yes, of course.... and with 100 lines in mql4 you earn the word

I alway make a simple question... what's your job? are you this night to see how it starts and tomorrow to trade?

no, I immagine you are in your affidable backtesting... and doing another job to live!
