You have to define a level before you can change its properties.

#property indicator_level1 0

thank to reply; but as you can see there is still that line under new setting. ( pic. below )


here is it & change in source are highlighted .

what is wrong ?

There is nothing wrong. The other line is drawn automatically and I don't think there is a way to hide it.

thank you.
 
If you dont like the zero line, just 'overwrite' it with a level line with the same color of the background.

There is no way to hide this zero line, I tried everything.
The only workaround is to shift your indicator values by an offset.
