Few resources state that swing trading Roth IRA account would be difficult due to SEC's Reg T+3 which per SEC Website is now Reg T+2 effective Sept. 5, 2017.
Even prior to SEC's amendment, my thought was if I sell XYZ then immediately buy ABC, as long as my swing exit plan for ABC was 3 or more days later there would be no restriction whatsoever and I could then immediate rebuy XYZ or even ABC, rinse/repeat spacing my repositions 3 days apart.
Is my understanding above correct? Does this avoid "free-riding."
i.e. exit[ABC] --immediate--> entry[XYZ/ABC], as long as I held ABC 3 (now 2) days or more.
