Anyone who has used RH regularly should be well aware of how inept it is. Any spikes in volume or volatility, even on a single stock, bring it to it's knees pretty often. Like not just the last week, but even during calm periods. I've personally lost 20-30% on positions solely because RH was bugging out, thankfully I use RH just for "fun trades" usually <$100.
I cannot fathom having the balls to trade any real amount of money on the platform while being aware of these long term issues.
On the flipside I feel for new users and perhaps even generally inactive users who weren't aware of RH's incredible flakiness. I'd imagine (or hope to) the losses of most of those users were small, assuming they were new or casual and just testing the waters.
Even if one of my small plays hit it big on RH, the money would just go to my main account on TD (which has been smooth all week shy of a few hiccups Fri morning during record volume). It's been obvious for a long time that RH should not and cannot be trusted. If you're trading options with a $60K account on RH, well, I don't even have words for that level of ignorance.
