Indicator suddenly disappear from chart NT7

[freewind]

Hi,

I have a custom indicator I wrote for the correlation of 2 instruments for NT7.
It display on a new panel.
I see the indicator displaying correctly but when I scroll on the chart it suddenly disappear and not coming back even if I scroll back to the data I already seen existing.
I think it mostly happen when I use charts with more then 3 month backword data.
How can it be solved?

Tx in advance!

You would need to check your Control Center's log tab for any errors, likely you miss a CurrentBars check for all involved series in the script.
