What is Sentinel?
Sentinel is a platform that allows you to create real-time market alerts. You can create basic alerts based on attributes such as price, trade quantity, volume, and open interest. You can also script advanced triggers by using combinations of attributes (including arithmetic) and operators.
You can use Sentinel no matter who your broker is. If you are trading with Zerodha, you can log in with Kite if not then, you can signup with either your Google or Facebook accounts. Sentinel is available completely for free.
