I ran it from the terminal

The path was specified both ways to the terminal

He's looking in the wrong place. There's a history in the terminal.

Kill all terminals, leave one and you don't have to specify the path. It will find it by itself.

if not mt5.initialize():

But you write that the history of bars is missing.

Set it in the terminal settings

And EURUSD is definitely there, because I tried to load it from the terminal, where it is not in the market overview))))))

The terminal is running alone.

I set unlimited in the terminal - it seems to have helped, but I had set it earlier - when I launched from python - there was no effect.

Also the connection with the MQ server is terrible - maybe it influenced somehow?

In general, it is not right that there is a dependence on the setting for displaying history on the chart.

Thanks.

 

Good afternoon everyone,to the esteemed author thank you for the article.

Newbie question:

The augmented sampled data from the "augment_data()" function is not used in training, judging from the above code?

I attach a picture with file sizes

Thanks for the comment. Just noticed. Instead of this:

marked_data = markup_data(raw_data.copy(), 'close', 'label')

You need to insert this:

marked_data = markup_data(augmented_data, 'close', 'label')

Don't understand how should it work, I think we need daily time-frame before we calculate this or not?

You have no ansi in your path. Степан.
Try to install python for all users. That woul install python on c:\Program Files\python
Or something like that

Or install python on C:\python
Don't forget to change system path variable if needed
