I find the exact opposite of what you say one shoud not do regarding day trading/scalping options.. There is a way to profit from PFOF.
Oh really what less transparent and inefficient alternatives? Like central exchanges and open order books? Thanks for the caution.
%% I WOULD not assume options + options bid\ ask are the worst deal just because Citadel Secutities + most of market makers make the most money , by far\on those.............................................................................................................LOL But my own P& L on them , IBKR exit on that market on them +decay may make a difference also/LOL HOOD massive PFOF + SEC fine may have hurt thier stock price. Citadel Group actually urged the SEC to ban PFOF in 2004, but its been so long from that comment, maybe the SEC should leave well enough alone.......................................[ FEB 16\2021 Better Markets 501[c] [3] article
