Aurora FX EA Source Code

This page gives you the Aurora FX EA free source code, the .mq5 file itself and not a compiled robot you have to trust. The engine is TSI crossover, and you can rebuild any part of it.

• Platform: MetaTrader 5, a single .mq5 file
• Strategy: TSI crossover
• Price: free, a free account is all you need
• Licence: study it, edit it and, if you want, rebrand it

In short, you get exactly the file we publish, and therefore nothing stops you from rebuilding any part of it.

How the Aurora FX strategy works

The True Strength Index smooths momentum twice, so it answers whether the push behind price is growing or fading without the jitter of a raw oscillator. The robot reads its direction and its crossings with the signal line.

Two averages of different length cross when the short term pace changes against the long term one. That crossing is the oldest trend signal there is, and it works because it forces the robot to wait for a change that already happened instead of predicting one.

Because every condition has to agree before a trade opens, the robot passes on plenty of moves. That is the trade off it was built around.

What is inside the Aurora FX EA free source code file

• The TSI calculation, with both smoothing periods and the signal line.
• The two averages, with their periods and the direction of the cross.
• The risk block, with the lot sizing, the stop loss and the take profit.
• Finally, every input with its default value, so you can compare it against your own broker.

How to compile and run it

1. First, download the .mq5 file from the button at the end of this page.
2. Then open MetaEditor 5 from MetaTrader 5, with F4 or the editor button.
3. After that, save the file inside MQL5 and then Experts, and press Compile.
4. Finally, refresh the Navigator and drag Aurora FX onto a chart.
5. Run it on a demo account first, and read every input before you go live.

If the compiler complains, our guide on compiling MQL source covers the usual causes. In most cases it is simply a missing include or the wrong folder.

What you can change

The second smoothing is what separates a calm reading from a nervous one. Increase it if the robot enters too early, reduce it if it always arrives late.

Before any of that, however, look at the risk block. After all, a good entry with the wrong lot size still empties an account, and therefore the sizing deserves the first pass rather than the last.

More robots like this one are in the trend following source code, and the paid catalogue with documentation and support lives in the MT5 source code section. The idea behind the true strength index is explained well on this reference page.
