Alexandr Bryzgalov:
Something I haven't tracked: is it already possible to edit the quote history programmatically in MT5?

And then draw a graphical trade on it???

to draw their own charts

you see, i'm not happy with the ones i have)

I've had it on "submitted for verification" for a week now.

That's the thing, it's not always good. Try

Print(_Point);

on the five digits.

on a five-character character.

By the way, why are "_Point", "_Symbol" instead of "Point()" and"Symbol()" still commonly used? After all, everything with "_*****" is a relic and legacy of the old language?

This is because "_Point" is a variable that stores the point value of a character, and"Point()" is the function that retrieves that value.

By applying "_Point", we will get the point value sooner.

The system function Point() is actually inline and is converted into a simple access to the _Point variable

Unfortunately, I'm not a developer, so I take my knowledge from the description in the manual.

But "someone" must write data in _Point :)

Yes. Some constant variables are initialized before initialization of mql-program.

My remark about inline was just about not being afraid to use functional writing. And if someone decides to save counters on direct access to _Point variable, nothing will work.

Personally, I only use direct access to _Point variables out of old habit
