Hello everyone,

I am looking for an "MT4 to ThinkOrSwim bridge" either as a product or a way to code it, but especially as a coding project. Perhaps using the ToS API.
a program in MT4 will generate the signals and the trades will be placed in ToS
Thanks

It depends on your level of programming skill. What I would do (and if this is too complex, I could try to come up with something simpler) is use the MT4 Webrequest to send a message to a Python Flask application running locally on your machine which parses this message and sends the appropriate trade signal to your ToS account.

Check out this API reference:
docs.mql4.com/common/webrequest
flask.pocoo.org

So instead of having a buy or sell action in MQL, you would send this message with data that can be parsed by a simple Python application.

MT4 side:

 

Code

res=WebRequest("POST","127.0.0.1/buy",NULL,0,NULL,NULL,NULL);

Python side:

 

Code

@app.route("/buy") def buy(): try: # add your ToS API logic here return "Success!" except: return "Failure!"

Hi lamden

Thanks for your reply

I know next to nothing except for some basic exposure with coding in php script in a apache / tomcat environment.

Would it not be possible to call the ToS web service directly from the mql code ?

You can. I guess I'm just partial to Python so I'd write a middle layer so I could get it into a language I know :P

You should be able just to call the endpoint via MQL but you will have to fiddle with their WebRequest API which is not as straightforward as other languages.

That being said, if you don't know any other languages, just use MQL and you'll be fine.

I'm trying something similar, but for a reason I can't even connect my TOS account using MT5 or MT4.

I was wondering if you had any success and could share some thoughts on how to do it?

Thank you!
