Literally use it for 5 minutes and you’ll understand.
1. Excellent watch list functionality including showing pre-market change separately from regular hours change.
2. Automatic alerts when any stock hits a new 52 week high or low as well a 5 or 10% move in either direction
3. Ability to trade starting at 4 AM which is at least 3 hours earlier than almost every other brokerage. This allows for earlier trades on big news.
4. Best mobile charts including the ability to show candlesticks with numerous indicators at many timescales. You’re not stuck with the bare Robinhood charts.
5. Excellent market information section showing top movers, highest volume, upcoming earnings, breaking news
6. Detailed information on large inflows and outflows for every stock
I have many more but I’ll start there because the charts and watch list alone make it easily better than the competition.
