Personally, I don't. I see it increasing commissions for brokers (duh), increasing the number of inexperienced/undisciplined traders who lose money, and just not making that much of a difference for the people who have been doing it for a while.
I only use one account for day trading, and it's composed mostly of around $10K of SGOV "ballast", $20K-$25K of my bull call spreads, and typically around $5K of "play money" I use for day trading.
Do you anticipate more day trading in any of your smaller accounts due to the change?
