Unfortunately, without the source code, this opportunity remains just words to me. There's a lot I don't know, and the start of self-study should probably be something practical to start with, something you can spin right away.

If you're just starting out, it's better to get familiar with the language itself, it's very different from C++.

otherwise, it's packages... lots of packages/modules for all occasions that are googled

Trying to answer at least primitively for myself the question "what can I use it for?". The answer "for self-development" is not accepted for a long time.

Therefore, I would like to see various cool examples from various fields in this thread. The most effect-causing one is visualisation, which everyone can try.


To calculate a correlation matrix with its graphical representation does not catch on, unfortunately.

I guess we have different ideas of beauty, I don't need visualisation at all and it doesn't evoke any emotion at all

I have never touched on the notion of beauty or the need for visualisation in this thread. I was talking about something else entirely.

I uploaded the ticks to a graph like this (1 million), you can save it in html

I attached a web page, it weighs more than 70 mb of course. Like this was to surprise or something else? Scaling, all that stuff.

Well, here's a simple example showing that it's much easier and more convenient to visualize tick history in Python than in MT5. Thanks.

 
Is there any code on how to pass an array of simple structures both ways?

Any code on how to pass an array of simple structures in both directions?

there is only sockets in byte form, I wrote a short article about exchanging through them, maybe next week.

Byte array to structure array (and back) casting in Python will be there?

No, into a regular array... you need to think what is a structure array in python, is it just a dataframe object with heterogeneous data

Anyway, you need to look specifically at the problem, it's hard to say and I haven't done it before.

i can write an article later, it's the first time i'm doing it myself
