Overnight Buying Power vs. Day Trade Buying Power

TradeStation uses the greater of Overnight Buying Power or Day Trade Buying Power to determine if an order should be accepted or rejected. In cases where an order exceeds both values, the order will be rejected. If the order exceeds only one of the values, a Buying Power Warning will appear to notify you that the order could result in a margin call. The warning will provide information on the type of call and approximate amount. Once the information has been reviewed, you will be able to send or cancel the order.

  It is your responsibility to enter orders that remain within the buying power for your trading style.
