Are there any special conditions on trading stocks when the markets are closed?
Orders placed when the markets are closed are subject to market conditions existing when the markets next open. Any equity requirement necessary for trade approval will be based on the most recent closing price of the security that you intend to buy or sell. Because of fluctuating conditions, the ultimate execution price may differ at times from the most recent closing price. When placing orders when markets are closed, carefully consider any limitation you may wish to place on the transaction. Fidelity reserves the right to refuse to accept any opening transaction for any reason, at its sole discretion.
