п. 5. :)

• You don't need alerts - just do Print().
• You need to sift events by:
• lparam
• dparam
• and sparam

I can sift it out. But my question is about something else.
I'm trying to understand (my head isn't just for wearing a hat, right?) if this function works correctly. Is it supposed to be like this, or is there something wrong?

Trying to get an OnChartEvent call on a mouse click on an object.

...

Here is what is passed for"CHARTEVENT_OBJECT_CLICK"

Event	id parameter value	lparam parameter value	dparam parameter value	Parameter value sparam
The event of a mouse click on a graphical object	CHARTEVENT_OBJECT_CLICK	X coordinate	Y coordinate	Name of the graphical object where the event occurred

That is, you need to catch id==CHARTEVENT_OBJECT_CLICK and sparam==name of your object.

That's what I thought at first too. But string gives name of object, which was clicked. So it seems to be an output parameter.
Or am I wrong?

That's what I thought at first too. But the string outputs the name of the object that was clicked. So, apparently, it's an output parameter after all.
Or am I wrong?

Do you need to catch a click on an object? I gave you a hint on how above.

Yeah, yeah, I think I've got it.
The function itself is called by any event (both mouse and keyboard), and you need to filter the right event inside.
Thanks.

There are several events(types of events): click, create, change properties ... So first you have to sift out events by ID, then by sparam.

Yes, thank you. For some reason, I thought, that it's possible to sift at a level of function call. And I wanted to sift out everything by id, so I put id in the function call.
"Well, crazy, what can you take!"))
And on the inside, of course, it's easy. Thanks again.

I don't want to create a new topic for a small question, maybe newcomers will also find it useful to know, like me.

At what time is it possible to submit new applications for freelance work?

If I already used all 10 yesterday.

Can anyone tell me which way to go? Excel has new functions "Forecasting Functions", etc. - e.g. "PREPARTS.ETS", "PREPARTS.ETS.DOVINTERVAL".

Is there anything similar in MQL5? I.e. input data array - output predicted array.

To be able to build a new line as in the screenshot, white line in the bottom indicator.

Friends, help a dummy. The idea is as follows: When the "Ind" variable reaches a given level, we switch to waiting for "Value" to change direction while waiting for "Ind" not to be checked again.

   if(Ind[0]<=-0.7)
     {
      while(Value[3]>Value[2]<Value[1])
        {
         if(CopyBuffer(InpInd2_Handle,1,SignalBar,3,Value)<=0)
           {
            Recount=true;
            return;
           }
        }
      if(BuyPosOpen) BUY_Open=true;
     }

What is the right way to do it???
