REGULATION T CALLS can be met within 5 business days, so I can consider this a 5 day overnight buying power? Like I over purchase a stock and bet a run within 5 days then sell it at the 5ths day? If I regularly abuse this rule, what will happen? My broker stops giving me margins, SEC disallows me from trading stocks? My stock holdings all only require 30% margin requirement, but somehow my total portfolio requires 50%. I hope I can get more overnight buying powers. Any retail broker is giving more than 1:1 buying power?
