On markets with an order book enabled, the detail trade panel offers Market and Limit modes. Read How trading & liquidity work first for the difference — Market buys go into the shared USDC pool; Limit orders rest on the book until they fill or you cancel. Resting orders near the midpoint may qualify for market reward pools — see Market rewards in Docs.

Place a limit order

1. Open a live market detail page.
2. Connect Phantom and sign in when prompted.
3. In the trade panel, switch Market → Limit.
4. Pick Buy or Sell, outcome (Yes/No), limit price in cents, and size.
5. Confirm — resting orders appear on the book; crossing orders may open Phantom for USDC settlement.

• Bid/ask depth appears on the detail page when the book is enabled.
• Open orders show in Portfolio and on the market detail book tab.
• Cancel from the book row, Portfolio open-orders section, or the order detail modal.
