iqoptionapi | IQ Option API 4.x | TLS library

After second-reading what you wrote (and edited) I can see you want:

• a symbol synchronized with iqoption [ through your proxy / remotely ]
• The symbol could be used for backtesting
• The symbol could be used for on-screen live/strategy/indicator run

That implies operations outside strategy/indicator which MT platforms do not allow in an automated manner - you can achieve it manually by providing a data package, parsing it to CSV and importing to custom symbol creator. Well documented here.

Unfortunately, you choose a platform that by-design stands for self-contained strategies and indicators, more for beginners than professionals taking it seriously.

Refer to the link I provided and see for yourself. The official doc states you can create a custom symbol via mql ref, yet even though they state, in the foreword, it allows 3rd party providers - it's not referenced anywhere else and does not show any integration possibilities.

Problem here is that iqoptionapi/ws/chanels/candles.py module from latest PyPI version differs from Github's master branch version and there is no amount parameter (it seems to be equal to 2).

In master branch:

It looks like IQOptionAPI uses websocket-client, which is asynchronous. Sending a request will return immediately, without waiting for a response from the server. You are checking for the response before you have received it. As a result, what you are getting is actually the result of the previous request. That's why it corresponds to the length of the sleep you use.

I don't immediately see a way within IQOptionAPI to make a synchronous request or get any sort of feedback when the response comes in, but it would be best to look a little closer and see if there is indeed a way. As a workaround, try inserting a couple of seconds of delay between the request and checking the response:
