PDT situation
No expert but think if you were Long prior day, sold in am,
bought SAME stock at 2 pm, sold it at 3:55 pm that would
count as 1 day toward PDT count of 4 rounds within 5 days.
But if Long prior day, then sold half at 1pm and second
half at 3 pm then not counted as two or even one since was still SAME stock Long from overnite.
Pretty sure selling pieces of same stock, same day won't
kick back (not 2 rounds since still same stock).
But buy & sell partial same day, in 2 DIFFERENT stocks, yes that's 2 counts toward getting PDT status in that 5 trade day window. Won't kick in PDT alert unless you continue to raise
the PDT count to tipping point within the window.
Would have to lay off for a few days or just hold overnite
and sell, buy only (if same stock) next day.
Oh and rem that this applies to pre & post aft hours. Trades there are counted as if part of the regular day so can't avoid
it that way. Best to get margin accounts in kids' names, wife, mistress, and pet doggie. g/l
Pennies not a zero sum game as much as some zero game.
