I also would ever use Robinhood instead of a reputable broker like TD Fidelity Vanguard IB etc. But not for the reasons you stipulated. Back office systems aren't put in place to "fleece" anyone.

Back office systems are exactly where Citadel, the market maker, could put a tiny little window to peep at data they shouldn't, so they can frontrun every trade retail investors make!!

The secret ingredient is crime ;)

Sounds like they found a way to make the plot of Office Space work in real life.

Making that scheme work wouldn't be the hard part. The hard part is staying out of prison.

I am not convinced this is true, but I see that the possibility is there, and it wouldn't even be the largest stock market scam that came to light.

Doesn't every single large broker frontrun this way? That's what I was told by former wall street programmers.
