> Broker apps like Robinhood will be absolutely overwhelmed with sell orders

Shouldn't be possible. Most of the messages to the orderbook, by orders of magnitude, would be market makers doing add/cancel, which isn't something that comes from RH anyways.

How often is one particular user going to send in an order? 10 times a day if they're particularly busy? Doesn't touch the sides. The internet facing gateways can be scaled up easily if that's even needed, they aren't latency sensitive. The inside towards the exchange can be made extremely fast.

I've built systems that do this.

Robinhood experienced several outages in March 2020 because of large volumes of trading.

A system could be built to handle this. Robinhood's likely hasn't been considering the notable outages they've had.

I'm on schwab. I had a hard time executing my sell. Luckily got it around $450 haha. But only 1 share for fun. I think I had to try like 8 times for it to go through. I also had a hard ish time canceling pre-market limit orders.
