I tried it this way:

if(id==CHARTEVENT_OBJECT_CLICK && sparam=="button1")
      ObjectSetInteger(0,"button1",OBJPROP_STATE,false);

But when you click, the button just visually doesn't seem to click, which makes sense.

That'll do, thank you.

The entire programme is delayed. Not good... For a simple variant, of course, it's fine. But for normal - you need to poll the values of the pressed buttons in the millisecond timer and, if after pressing the button the required delay time has passed - set a flag.

In a closed market, be surprised how a button like this works

Try this.

Better yet, prescribe,

if there are no open sell orders, delete the sell line...

Yes, it's not good. Is it ok?

     if(id==CHARTEVENT_OBJECT_CLICK && sparam=="button1"){
       ulong ms=GetMicrosecondCount();
       for(;;){
         if(GetMicrosecondCount()-ms>100000){
           ObjectSetInteger(0,"button1",OBJPROP_STATE,false);
           break;
         }
       }
     }

Isn't it equivalent to Sleep(100)? After all, the program will hang in a loop until break is executed.

Please suggest an indicator for crossing two slides with an alert?

Yeah, that's not good. Is that OK?

And if "ms" is made global

ulong ms=0;
//+------------------------------------------------------------------+
void OnChartEvent(const int id,
