It’s probably hard to change the UI of an existing brokerage service though. Tons of testing required given the potential size of the transactions involved.

have you seen vanguard lately? they randomly switch you between an old and new ui. its pretty bad

Vanguard UI is so bad for actively trading or even checking your positions that at this point I can only think its somehow part of their brand where they think they would actually lose customers if they updated it.

That’s called AB testing, baby

Looks like the number of net funded accounts increased by 300,000 in Q4, so they're still growing their customer base.

> UI can be replicated.

It has not been, so far, especially on mobile.

WeBull has the best mobile app hands down. Robinhood is the “simplest” I guess but is much less useful

Because why?

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.

Not so easy. You don't want sink a bunch of cost into replicating a competitor to just get sued for copywrite infringement.
