Hi @Sanjay2704
Thanks for your kind words about Dhan, glad you liked Scalper. In case you missed, we recently (just last week) also introduced Scalper on our Options Trading app. We wrote about this here: Introducing : Scalper on Charts on Options Trader app
Regarding volume bars., we have mentioned this earlier on community as well - Nifty and BankNifty are not tradable on exchanges directly and hence the volumes are not available. We had checked this, and were informed that the volume bars displayed on few charting platforms are derived data (not real-trading data). We prefer to show trade data only if it is available directly from exchange, not a derived metric. In such scenarios, it may lead to misleading setups or studies.
Feedback noted on the landscape mode for Charts, we will see how we can improve this. There are some restrictions because of the charting library we use.
