Sure, I will attach the template.
This happens when you load this indicator in more charts at the same time, for example If I have it on 3/4 charts it works, otherwise with 7/8 charts it starts telling me that it is too slow in some random charts.
Also I noticed that if I put this indicator in Multi Time Frame for example (Indicator m5 chart m1), the volumes are broken and If I reload the indicator some of them repaints, I will attach also an example of the specific point where this happens.
Finally, sometimes in some points of the chart the volmues disappears, or they are zero, and I only see the center line
