A market order can execute only when matching orders are available.

Check these common causes:

• Insufficient balance: Your wallet must cover the trade value and fee.
• No liquidity: There are no matching orders on the other side.
• Not enough shares: The available quantity is smaller than your requested order.
• Trading ended: The market expired, entered resolution, or is already resolved.
• Price changed: Another trader filled the available order before your transaction completed.

Try reducing the order size or placing a limit order. A limit order may wait, fill partially, or never fill.
