There are different types of purchases. These are set automatically depending on when the order is placed.

• Market buy: This order executes immediately at the current market price. It will complete at the best price available that day, within market hours. If it doesn't complete, it will stay active until 3 pm CST of the next business day. If the price doesn't match what you confirmed, we'll cancel it to protect your investment.
• Automatic limit buy: This is an order with a limit price you set. If your price is at or above the current selling price, it executes immediately at the best price available. If not, the order stays open until the market reaches your price. You choose the validity period: 1 day (it cancels at market close if not completed) or 90 days (it cancels after that period if not completed). In both cases, your reserved funds are automatically released when it cancels.
• Scheduled buy: This order completes when the market reopens. If the price changes by more than 5%, the purchase will cancel to protect your investment.
