Buy and sell contracts

Click any contract on Markets or Home to open its page.

Reading the page

• The headline is the last price per contract, the same price per GPU-hour, and the change over 24 hours.
• The chart plots the price. Switch Contract / GPU-hour to change the unit, pick a range from 1H to ALL, and toggle between line and candles. The Depth tab draws the order book instead.
• Order Book lists resting asks (red, above) and bids (green, below), with the Last trade and the Spread between them. Switch the size column between USD and GPU; the −1+ control groups price levels. The bar at the bottom is the buy/sell balance of the book.
• Trades is the tape: every fill on this contract, newest first.
• Market Details, below the chart, has the contract’s month, hours and volume.

Place an order

In Place Order on the right:

1. Pick Buy or Sell.
2. Pick the order type from the dropdown:
   • Market fills now at the best available prices, up to Max Slippage (5%) from the last price. Nothing rests.
   • Limit rests on the book at your price, a whole number of dollars per contract, until it fills or you cancel it.
3. Enter the Size in GPUs (whole contracts). Max fills in the most your Balance buys, or everything you hold free when selling.
4. For a limit order, enter the Price.
5. Check Total. Then click Buy or Sell.

The order goes to the exchange and the result shows at once. A limit order that doesn’t fill appears on Home under Orders, with a Cancel button.

You can only sell what’s free: contracts in another resting sell, or locked by a deployment, don’t count. The panel tells you how many are free.

Fees

There are no trading fees today. A fill settles at its price.
