Good day! Can you please tell me how to implement this case?

I created a button in the indicator, when you press it, a certain condition is fulfilled. But when you switch timeframe or chart, it is reset to the initially NOT pressed state. I want it to happen only manually - by pressing the button.

What to do? I feel that the solution in one line, but experience and knowledge is not enough.

Good afternoon!

Can you tell me if it's possible to create a script that, when dragged to a certain bar, would give its date? Is it possible to do this? If so, what function? Been reading the handbook and forums but haven't found anything so far. Give me an idea or direction. Thank you!

You can, here's ready to do someone, in the folder indicator drop

You need the source code, maybe you'll see.

otherwise read in the help when OnInit() is executed

The code itself is very old and voluminous, the button was implemented in it by gut feeling
I am attaching the code stripped of all unnecessary things, except for the button itself

We need to implement so that when you change the timeframe button is not pressed, is this even possible7!

I've posted one code recently, there, it has a button in it. May be useful for understanding...

Greetings. Can you please tell me where this value comes from when you subtract?

"Bid: ", Bid," buyPrice: ", buyPrice," Bid-buyPrice: ", Bid-buyPrice

buyPrice=Bid; set at opening

Comment("   Bid: ", (string)Bid,"   buyPrice: ", (string)buyPrice,"   Bid-buyPrice: ", string(Bid-buyPrice));

Or use DoubleToString() instead of (string) with desired accuracy.

Thank you. I used double(Bid-buyPrice) to calculate

Only why was it like this?

Thanks, but there's a line like this:

"Using the debugger is a new feature of MetaEditor 5, it is not present in MetaEditor 4"

There is. On current data. MT5 has debugging on historical data.
