tv.dhan.co incorporates the charting library that TV gives to brokers and is hosted at Dhan end. This platform doesn’t have all the native features of TV as TV limits what it gives to third parties. So you cannot access TV community scripts on this platform.
However native tradingview has Dhan under broker panel. So it is possible to analyse using TV community scripts and manually trade from native TV via dhan.
If you want to use community scripts from native TV and autotrade with Dhan then you have to use the webhook integration provided by Dhan.
