We use Esignal Chart System for several Years.
All our strategies are created and backtested in Esignal.
The language in Esignal is much more powful and complicated than mql4.
We could only translate our strategy for Spot Gold into MT4 EA.
Although the profit is almost 50% off in MT4, we think the result is still acceptable.
So our manual trading result will be more profitable than the EA itself.
