I am pretty sure webull did in the morning session and Etrade did in the afternoon. Not sure about other brokers only allowed to hold or sell.
Webull Follows Robinhood in Blocking GameStop, AMC Trades After Being Suggested as Alternate Trading Platform (newsweek.com)
E-Trade confirms it halted GameStop and AMC stock, will let you buy some Friday - The Verge
Thanks.
My sense of it is that what TDA and E-Trade and the like did was technical - it was impacting their trading functionality. But the limits didn't last that long (except for margin and credit-based trades, which is a different issue). Robinhood, on the other hand, appears to have taken the action it took for business reasons - it was not comfortable with the clearing risk it was taking. Or at least that's their public explanation, it could be more problematic than that given their relationship with Citron.
Perhaps a hearing on the Hill would shed more light on it. But I don't think lawsuits are going to get anywhere.
