Metatrader 4 API in C++

Using a platform for trading, however, would also like to add MT4 trading capability, thus wondering if there is an API in C++. Ideally, via API to connect the platform to MT4 server of a broker and not use the MT4 client. I saw there are some in .Net / c#, however, I wonder if there are any API available in C++ and if anyone knows of it. Thank you.

There is none at the moment. Everything around (including .NET, C#) is more or less scam as under the hood all those products currently offered - who pretend to be an API - are in fact MQL Expert Advisers dropped on the chart of a regularily running terminal. Then those fancy products connect to the EA in the terminal (e.g. via sockets or named pipes), send trade commands to it and let the EA execute the command. You can imagine that the whole process is quite slow and unreliable.

Years ago there was a C++ API for MT3 and in the beginning there was a non-public API for MT4. That MT4 API was reverse-engineered by traders and people started to sell it for ridiculous prices. After that MetaQuotes pulled it with build 600, and the rest is history.

I attach the public MT3 and the MT3 API files if you want to play with it. Today it's of no real use but it serves as a good example and gives some insight in internal structures and data flows.

the MT3 times were the good times at MetaQuotes , when things just kept improving , whereas nowadays the MT5 times are just the opposite , things go worse and worse

MetaQuotes should take a good look at themselves and start all over again with that MT3 spirit in mind

Thats with most of the things nowadays, people think its better because it has better optics but under the hood is a bunch of crap. Never used MT3, but doubt there is any broker left with one nowadays.

I recommend to have a look at Spotware (cTrader). There is only a good handful of high-quality MT4 brokers out there and you can distinguish them easily from the bucketshop crowd by either offering a FIX api themself - which you can interface to in C++ - or by having partnered with Spotware to outsource the FIX implementation/binding. So you can write a C++ connector to Spotware which in turn routes to the same liquidity provider and price feed as their MT4 bridge does. One exception is Dukascopy which I also recommend to have a look at, but their API is only in Java (which shouldn't be a problem).

I didn't use it because without documentation is difficult code it. But your link is very good since they give you that documentation directly. Anyway I'm more interested in mt5 since is current platform for metaquotes

OK thanks. I would like to give this API trial a go... if anyone has experience with it then I'd be very interested in hearing about it. Don't want to spend a few grand just to find later that it's some hack job.

Why pay $ when you can use the mt4/5 terminal as a means to connect your custom/third party software to it (and also as back-up)?

Because there are projects who cannot afford running hundreds of terminals parallel just to get updated account information. Think of FxBlue, for example. Another example is if you want to aggregate prices.

Agreed - running hundreds of terminals consumes plenty resources. And then when markets get choppy, your resource usage goes through the roof - this is not a practical solution for bigger projects.
