I think I succeeded. Panagiotis Charalampous, could you look at the correct code?

Exactly. Unfortunately, I can not understand how to calculate the indexes correctly. Erasing the graph works. However, I can not draw it correctly again. I have been struggling with it for several days.

Thank you, exactly the effect I tried to achieve. Unfortunately, my way was wrong.

26 Feb 2019, 12:22

It seems that the code works, however, not as I wanted. The SMA indicator is drawn in the chart only from the moment when the "showSMA" condition is true, not in the entire chart.

Is there any way to show and hide the working indicator with a code?

Hi lw3010996,

The reason you see nothing is because showSMA is always false.

if you remove this piece of code

               System.Windows.Forms.Application.DoEvents();

It should work fine.
