Can I use languages ​​other than MQL4 on MetaTrader4?

Question

I have the task of porting a C # market strategy to MetaTrader.

• Is there any way to automate this work? (For example, is it possible to parse C # into an AST, and then make a translation?)

• Does MetaTrader accept other languages ​​in any way?

Answer 1

Bottom-Up Approach - Architecture-wise

Yes, you can simplify the problem and make MT4 Node, which is immediately connected by a peer to your current C # strategy.

This helped me organize cluster computing , communicating a massive parallel with a crowd of MT4 nodes.

MT4 can become anEventFEED -er Node with a more sophisticated “scalable formal message processing scheme” in a very smart way.

Do you want to have a CLI interface for the MT4 node (s) command - one as anEventFEED -er, the other as anXtoACTOR Node - selectively, with the syntax and grammar of the CLI instructions (not to mention test-automation, etc.)?

Do you want to have a central < syslog daemon to load HFT traffic loaded by MT4 node (s) and automate + administer monitoring and script maintenance tasks?

Do you want the external GPU engine / cluster engine to interact with the client / server using MT4 EA based on per-tickEvent?

The basics of ZeroMQ and / or nanomsg will allow you to design and develop many-to-many (node-based) and any-to-any (language implementation systems).

MT4 / MQL4 has a direct intelligent shell for ZeroMQ →> thanks to Austen Conrad on GitHub MQL4ZMQ

Thus, your project can start in an abrupt manner and is not dependent on any specific network gridlock (DLL moving sands et al)

Engineering built-in features save a lot of time and effort and do not reinvent the wheel

Answer 2

the short answer is no, but there is the ability in mql to import DLLs. so you can wrap your C # lib with the C ++ / cli library, which is functionally expanded through the export of functions, you can even start the timer in mql and implement a rudimentary message pump.

Update: MT4 can only access regular unmanaged DLL calls. the reason you should use the C ++ shell is because C ++ has the ability to create unmanaged standard calls. any other language in which you can create standard calls can also work.

In addition, you need a shell if you want to use other languages ​​that do not support standard calls. You can just write all your code in C ++, and the whole shell concept will be obsolete.

Answer 3

What about GET / POST requests and a text API web service?

You can use your C # strategy to update a text file on the Internet with a triple signal:

 -1 SELL 0 HOLD 1 BUY 

Then use MQL4 to read a text file once a minute for a trading signal.

How technically how to do it; Unfortunately, I am a python programmer, not MQL4 or C #, so I can not help.

Answer 4

Yes, you can use C # using some third-party solutions, such as NQuotes http://www.nquotes.net/ , which is essentially a ready-made DLL for general use (as Dmitry said, you can create your own, but it requires a little work).
