What is Buying Power

May 14, 2020

The day trading rules will affect your buying power. You can trade up to four times your maintenance margin excess as of the close of business of the previous day.

It is important to note that your firm may impose a higher minimum equity requirement and/or may restrict your trading to less than four times the day trader’s maintenance margin excess. You should contact your brokerage firm to obtain more information on whether it imposes more stringent margin requirements.
