add immediately H-Line

[alidavoodi]

Hello
I have a problem and I tried every method to no avail...
I add a button in the "on chart" section and specify that when it is clicked, it will add a line on the chart.

But when I click on the button in Metatrader, it takes a tick to add the line. But I want the line to be added immediately and not wait a tick.

and I create the blocks in the "on chart" tab
But after clicking on the button, one tick later, the commands I have written are executed...

Maybe the chart is just not updating the results.

Put ChartRedraw(); in a custom mql block.
