Here's my code.

Checked it, everything works, either you're changing the wrong code or compiling or ... Well, reset the terminal or something, but it's definitely working.

I have checked everything more than once. If you want to be sure - I can show you via TeamViever

I have already checked everything more than once. If you want to make sure - I can show you everything through TeamViever

You'd better (additionally) attach the code as a file to the message - as in the text, the code is not designed (no header) and it is not clear which terminal the code is for.

You have an extern uint. What do you want? Well, read the answers carefully.

Now I see, I was looking for an error

[Vladimir Karputov]

Alexandr Sokolov:

Here is a correctly created indicator - there is a header, no "strict" - they are not needed in MQL5, no "extern" - it's the last century, while the indicator doesn't display anything, we indicate at once the number of buffers "0" and the number of constructions "0":

#property indicator_buffers 0
#property indicator_plots   0

Here's the whole code:

Further on, we can dance from this code.

You can dance further on this dummy.

This is not the last century - this is a really cool thing.

The input cannot be changed, you have to re-assign it, which is wild. There are no such problems withextern, the only problem is that for some reason it does not work in mt5

The help will tell you what it is for. And yes, it is correct that the parameter entered by the user cannot be changed programmatically. At least something can belong to the user :)
