Thank you very much. Since Backtest doesn't work, Can I still use EA running on Real trade?

Meta Traders is the world's second worst strategy backtester. It is only tiny better than Win RAR, which is absolutely useless on that purpose. Win RAR at least can make your EA smaller.

Footon, MT backtester was slow till the previous release. Now it is dead.

However, you are right. Probably, I have to add a "Calculate" button, to make FSB 1000 times slower and 3 times more expensive. Then, it will be more creditable.

It is true. We cannot rely entirely on Meta Trader.

However I prefer NinjaTrader instead of JForex. Ninja Trader has a new upcoming release - v8. They announced a long term support for at least 10 years for that release, so I think it is a good point for investment. Other possible variants are Quick Trader (it's a new platform currently in development) and cAlgo. All these three use C# and I'll try making the exported strategies working without any change in the indicators. It is much better than the proprietary MQL especially when there is no guarantee that our EAs and indicators will work tomorrow.

Once I started with FSB I believed that mql code is a must. Now I prefer to use only bridge and cs code in indicators.
I do not care with mql so much any more.
Relative to results I do not have yet but I do also another job.
The reason is that and not FSB. Brokers make many tricks. Monte Carlo is very useful to understand what happens with brokers and stay with them or find another one.
FSB gives opportunities to make the gambling more realistic for the trader.
By using it he can understand many things. I do not know any other software to offer so many ideas at so short time.

I just need to see Editor button, Compilation button and Save button to each of the Strategy Labels to change a bit indicators.

Relative to logics. I think we need to add some common logics used to any indicator and a smoothing indicator used to every indi a common way.
