What is Buying Power

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 we 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. A list of securities that have day trading and overnight margin requirements higher than the normal can be found in the Client Center on the Special Margin Requirements page.
