What is Buying Power

Under the Intraday Margin standard effective June 4, 2026, your buying power for intraday trading is determined by your Intraday Margin Buying Power (IMBP), calculated in real time based on your current Margin Excess.

Accounts with Margin Equity at or above $2,000 may access up to 4× their Margin Excess for intraday trading. If Margin Equity falls below $2,000, buying power is limited to 1× Margin Excess. Overnight Buying Power, which applies to positions held past market close, is calculated at 2× Margin Excess for accounts at or above the $2,000 threshold.

It is important to note that TradeStation may impose a higher margin requirement and/or may restrict your trading to less than 4× times Margin Excess for certain securities. A list of securities with elevated  day trading and overnight margin requirements can be found in the TradeStation Hub on the Borrow & Special Margin List page.
