Yesterday I wrote the code, it seems to work as it should, but only when I get to the top value of the array with the plus button, it resets to the beginning of the array and moves up the array again. What can I add or fix in the code, so that when it reaches the top value of array, further clicks on the plus button will stop at the top index and it will not reset to the bottom of the array? Or can the code be simplified in some other way to implement this button-clicking idea?

if(x >= ArraySize(scale_mas))
 ArraySize(scale_mas)-1;              //если х>= размер массива, то ....

Probably so.

Alexey Viktorov:

I guess so.

Tried that too, works the same way

Ivan Revedzhuk:

I didn't notice right away, what's the cycle for?

Alexey Viktorov:

I didn't notice right away, but what's the loop for?

Is there any way to do it without it? I just don't know what's best and I'm just doing what I think is logical.

Ivan Revedzhuk:

Well, the logic must be different. Pressing the button + increases the index of the array. Reached the maximum, it does not increase, but stays at the maximum. Pressed the button - the index decreased. Reached zero, does not react to pressing, stays on index 0.

Or was there some other idea?

PS; And who posted the example of working with flags, in response to this question and deleted it? Why did you delete it? After all, it's a really good solution to the man. Why would he need a limited array???

No, that was exactly the idea. I don't really know how to do it properly, so I did it the way I got it. But I've noticed that when the loop is running in the program, as long as I don't click the buttons on the chart, everything else doesn't work. It's like everything is paused. I don't understand why this happens, if there are any variants to implement the idea in any other way, I'd be grateful...

That's it. The problem is solved) without arrays and other stuff. It turned out to be much simpler))))

The second question came up. How can I set Alert triggering level in the code with setting arrow that appears when Alert is set via contextual menu with mouse?

Question on Alert

Please help, plz, is it possible to add a function to this EA, so that the EA set in the window EURUSD will open a deal with the same parameters, at the same time, but for GBPUSD, and EURUSD will not open.

vvs1:

Help, plz, is it possible to add a function to this EA, so that the EA installed in the EURUSD window would open a trade with the same opening parameters, at the same time, but on GBPUSD, and not open on EURUSD.

I'm sorry, is your head OK? Not only have you inserted the code in one place, but you've also left a huge amount of empty lines.

Don't you think you should have some respect for who you're asking for help?
