Gain Made $18k in less than 1 minute by accidentally sniping mispriced ask

I put in a large market order this morning, and somehow bought 1.9k shares at 75 cents each while the stock was actually trading for ~10$

I cropped out the ticker because it has <300M MC, but had to share this because this is so unbelievably regarded that I think I might have bought off one of you guys.

TLDR: I stole someone's shares for 90% discount because they probably mis-entered their limit order.

Asking for a friend, what happens if I set my limit order waaay lower for testing?

Depends on the broker and the volume. I've listed a sell with a small typo and the order fulfilled at market price instead of my lower limit. Thanks for looking out Robinhood, life can be hard for us regards

Yeah, I don't understand what broker sells for literally your limit price. I thought it was always just at least that price.

Yeah ppl like to shit on RH but that's one good thing about it. If I limit buy and it keeps dropping fast, I'll usually buy at a lower price. Same for limit sell but it keeps rising.

Robinhoods the shit, I happily switched everything over to it from a "real" broker

Usually, the broker will sell it at market or try to fill at best price. To me, this is a market maker error, not a broker.

Right? I'm not following this but I'm no expert and I'm on first cup of coffee. Doesn't sound like a limit order.

It's a lower limit not an upper limit ... as long as people have buy orders at higher prices your order will be filled at those prices.

OP needed to have a market with very low volume and be fast enough the robots couldn't react.
