1. Open a market
Head to the Markets page. Each card shows the market question, the YES price, and the implied probability. Click any card to open the full market view.
Reading the prices
The two prices you see — YES and NO — always add up to $1. If YES is 0.62, then NO is 0.38. Whichever side you click becomes your trade direction.
2. Choose YES or NO
Click YES if you think the outcome will happen, NO if you think it won't. The trade panel opens with the current best price and the depth available at that price.
3. Enter your size
Type how much USDC you want to spend. Signal shows you:
- The number of shares you'll receive
- The maximum payout if you're right
- The implied profit and ROI on a win
- The average fill price (for larger orders that walk the book)
4. Sign the order
Click Confirm. Your wallet pops up with an EIP-712 signature request — this is the order itself, not a transaction. You don't pay gas to place an order; you only pay gas when the order is matched and settled.

The trade panel shows real-time fill progress. Most orders against liquid books fill instantly.
5. Track your position
Your new position appears under Profile → Predictions. From there you can:
- See the live mark-to-market P&L
- Sell out early at the current price
- Add to or reduce the position
6. Wait for resolution
When the match finishes and the oracle posts the result, winning shares pay out $1 each in USDC, automatically. Losing shares simply expire. For more, see Resolution & oracle.
