i'm just wondering if, for example, i'm day trading and i sell my security, does the 3 day trades rule apply if i'm ONLY trading that same security multiple time during that 5 rolling day period, or can i trade multiple securities that same day? for example, i buy and sell stock ABC for 2 roundtrips, buy and sell stock CDE for 1 roundtrip, and buy and sell stock EFG for two round trips on the same day....basically my question is if you can make many day trades within the week if you switch off on securities?
