My favourite feature: Real-time L2 Quote

The feature that I used most frequently is Real-time L2 Quotes because it helped me to monitor the share price and my trading usually started here. The watchlists can be customised to display the stocks in the order I liked. I could also create group based on sector or region.
I can easily get to other features from here like analyst ratings and news. I used many features in Moomoo app. No trading platform is perfect and you may need some practice to find some hidden features. But Moomoo organises event like this to highlight new features and show how to use them.
