Sometimes on monthly timeframe you can't add indicators or attribute 43200 TF.
Sometimes it works for monthly charts when you put the Counted Bars to 100 instead of 1000
(for JPM stock for example)
- Open the monthly chart
- put the Counted Bars to 100 instead of 1000 and refresh chart
- attribute a timeframe of 43200 min
- open the 60 min chart
- put Counted Bars to 1000
- put ADR Monthly indicator
That's all.
Or simply use indicators on monthly chart with Counted Bars to 100 instead of 1000.
If it doesn't work with 100, try less...
Don't forget to put back Counted Bars to 1000 after your experimentation.
