Expert Advisor Testing Without Metatrader

EA Testing is now possible in Smart Forex Tester 1.0!

Expert Advisor testing is usually done in MetaTrader’s own Strategy Tester tool. Due to Metatrader’s license, testing EAs as a source code outside of the Metatrader terminal is not straightforward. And testing EAs as executables without violating MT license is virtually impossible.

We also started implementing our trading strategies as Expert Advisors, but soon dropped this idea. We got disappointed by drawbacks of MT4 strategy tester and se decided to develop our own strategy testing software.

In our software, we didn’t have to stick with EA formalism, so we implemented trading strategies as state machines. Which best suits our purposes. Also in our approach the logic of the strategy is more clear – compared to the case when strategy is fully defined by a piece of software.

However, due to overall popularity of Expert Advisors, we also provided in our software a partial support to the strategies as EA – on the source code level. This became possible when we added trading strategies as C++ code in our all-new Smart Forex Tester. C++ is very much compatible with MQ, the language the Expert Advisors are written in.

To test an Expert Advisor in our Tester, you need to make some straightforward changes into its source code. There are language changes and trading functions replacement.

First of all, you need to load the EA source code into our Tester and compile it. At this phase there might be some errors, as MQ is not fully compatible with C++. You need to fix that by making small changes in the syntax.

Next, we need to replace the market data and trading functions, like onTick() or orderSend(), with the corresponding interfaces to the Tester engine that are available to the trading strategy.

Note that the primary reason we added C++ support to our Tester was not to enable Expert Advisor testing. Programming environment is needed to give more power to the users to define their strategy.

And, ultimately, our goal is trading strategies as state machines. For that, C++ will be the way to add new blocks of the state machines – such as market signals.

Our Smart Strategy Builder will be a proxy between the state machine formalism and C++ code environment.
