As far as I understand it from mql5, the ChartEvent() is when you click the mouse . . . not when you are constantly moving it.

OnChartEvent() is an event handler for all sorts of chart events : https://docs.mql4.com/basis/function/events#onchartevent

Each time he moves to mouse a chart event is generated.

Can you please report that to ServiceDesk. Thank you.
 

When you click and hold down the mouse button to move a trendline, the trendline's value is set to 0. It is only when you release the mouse button that the new value will be set.

So while you are moving the trendline the value will be 0

Maybe, but this is the MT4 forum.

When I posted

I was making an observation. Whether or not that is how it is supposed to work, I don't know.

 

I explained it badly, I'm sorry.

ServiceDesk has solved the problem. (fixed)

Thanks all.
