Place Order
Two order types, two directions, one orderbook. Market orders fill instantly at the current price. Limit orders sit in the Polymarket CLOB until your price is matched — and earn maker rebates when they fill.
- Limit orders: set your own price — maker rebate earned, zero fee charged
- Market orders: instant fill at current best price from Polymarket CLOB
- Selling changes the input from dollar amount to token shares (25% / 50% / Max)
- Every order EIP-712 signed by your wallet — operator cannot execute trades for you
What Every Field Means
The trading panel shows all order parameters before you confirm. No hidden costs — every number is visible before you tap Trade.
Worked Order Examples
Two real-scenario walkthroughs — one market order on a short-term crypto contract, one limit order on a long-duration event.
Market order — BTC price direction
- Select Buy, Market, tap outcome button (e.g., UP 51¢)
- Enter amount: $1
- Panel shows: To win $1.96 at Avg. Price 51¢ (~1.96 tokens)
- Tap Trade — order fills immediately
- If BTC closes up: receive $1.96 · If BTC closes down: lose $1
Limit order — World Cup winner
- Select Buy, Limit on a multi-outcome market
- Set limit price: 12¢ · Shares: 100
- Total cost: $12.00 · To win: $100.00
- Tap Place Order — order sits in Polymarket CLOB
- Fills when someone sells at 12¢ or lower
Selling Positions
Switch to Sell mode to close an open position. The input changes from dollar amount to token shares — your holdings. Quick select buttons: 25%, 50%, Max. Sell proceeds return to your pUSD balance instantly.
You can sell before market resolution. Selling early locks in your current unrealized P&L. Token price at time of sale is your exit price — no need to wait for the market to resolve if you want to take profit or cut a loss.
