Show block if a condition is true

[After]

Hey guys !

I'm got an indicator which plot a line. I just would like to plot blocks (or dash or whatever) only when the value changes. Is there any easy way to do this ?

Thanks !

Hello After,


You could do this by comparing the current value of your indicators current bar value to the previous bar value. I have included our Help Guides on Developing Indicators to assist you further in getting familiar with building indicators.
I have included an example below of what this would look like.
