Mako EA Source Code

This page gives you the Mako EA free source code, the .mq4 file itself and not a compiled robot you have to trust. The strategy behind it is scalping, written in plain MQL that you can read in one sitting.

• Platform: MetaTrader 4, a single .mq4 file
• Strategy: scalping
• 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 Mako strategy works

A scalper aims for a small target many times a day, which means the cost of each trade eats a large share of the profit. Therefore the entry has to be selective and the spread filter is not decoration.

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 Mako EA free source code file

• The scalping exits, with a short target, a protective stop and the spread filter.
• 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 .mq4 file from the button at the end of this page.
2. Then open MetaEditor 4 from MetaTrader 4, with F4 or the editor button.
3. After that, save the file inside MQL4 and then Experts, and press Compile.
4. Finally, refresh the Navigator and drag Mako 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

Adjust the target and the spread limit together, because a target of a few pips stops making sense the moment the spread widens.

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 scalping EA source code, and the paid catalogue with documentation and support lives in the MT5 source code section. The idea behind scalping is explained well on this reference page.
