Using the Order Book

Mastering the Order Book is a key step toward becoming an advanced trader.

In our Getting Started guide, we covered on Making your First Trader, where the trade fills instantly at the best available price.

But if you think the market’s asking too much (or offering too little), you don’t have to settle. That’s where Limit Orders come in, giving you the power to set your price and trade only when the market meets you on your terms.

Viewing the Order Book

The Order Book is your window into the market’s heartbeat, every open order to buy or sell shares in a market is right here.

Let’s take an example: in the market “Will Ethereum exceed $5,000 in 2025?”, we’re viewing the Order Book for Yes shares.

• The Green side represents the Buy : The highest prices traders are currently offering to buy Yes shares.

• The Red side represents the Sell : The lowest prices traders are willing to accept to sell Yes shares.

You’ll notice a small gap, say 1¢, called the spread. Understanding this spread is key: it’s the space where opportunities live. The tighter the spread, the more competitive the market; the wider it is, the more room there is for a savvy move.

Managing limit orders

Your open orders appear just below the Order Book on each market page.

If you’re trading in multiple markets, you can manage them all from the Portfolio page.

Canceling limit orders

To cancel an order, click the red Cancel button below the Order Book on each market page.

You can also cancel from the Portfolio page if you have orders across multiple markets.

1. Go to Open Orders.

2. Click the Cancel button next to the order.

3. Confirm in the pop up dialog. The order disappears from the list.

To cancel all orders:

• Click Cancel All above the list, then confirm.

Congratulations, you’ve leveled up! You can officially wear the badge of an advanced trader.
