Hi @SAphadke
Thanks for your kind words about Dhan. There are two libraries for TradingView - one they use and the hosted one that we have enabled on tv.dhan.co and inside Dhan app & web.
Whenever TradingView extends any features to the library we use, we immediately implement that and make it available for our users on Dhan. Unfortunately the one you are looking for 1 second timeframe isn’t extended as of now. If it gets done, we will make it available on Dhan for sure.
Since you are using tradingview.com, suggest exploring the Free Webhooks that we provide. More on that is here : Introducing Webhook Alerts : Direct Order Placements on TradingView from Dhan
