Name your price

A limit order says: “I’ll buy at this price or better — and I’ll wait.” The order sits on Polymarket’s orderbook until someone takes the other side, or you cancel it. This is how patient traders get better entries.
1

Open the market

Click any market card to open the detail view. Select YES or NO.
2

Switch to Limit

Toggle from Market to Limit at the top of the order panel.
3

Set your price

Enter your price in cents. YES shares at 45c means you think there’s at least a 45% chance of this happening. Tick size is 0.01 (1 cent).
4

Set your size

Enter USDC amount or share count. The panel calculates the other.
5

Submit

Click Place Limit Order. It goes on the book as GTC (Good Till Cancel) — it stays until filled or you manually cancel.

​
GTC: Good Till Cancel

Your order lives on the orderbook indefinitely. It won’t expire at end of day. It fills when the market moves to your price, or you cancel it from the Portfolio open orders section.
Polymarket’s minimum tick size is $0.01 (1 cent). You can place orders at any cent increment — $0.42, $0.73, whatever you like.

​
Limit vs. Market: when to use what

  • The spread is wide (more than 3-4 cents between YES and NO)
  • You’re scaling into a position over time
  • The market is slow-moving (election weeks away, not hours)
  • You want a specific entry and you’re willing to wait

​
Pro tip: the stale limit trap

Set it and forget it works — until it doesn’t. If the market fundamentals shift while your limit order is sitting there, you might get filled on a trade you no longer want. Check your open orders regularly, especially before major events.
The best edges come from limit orders that other traders market-order into. You provide liquidity, you capture the spread. That’s the game.
