Trading uses your Spot wallet. If your funds are on Funding, move them first: How do I move funds between my accounts?

Open Trade in the top menu and choose the pair in the market selector, for example BTC/USDT.
In the order form choose BUY or SELL.
Choose the order type: Limit, Market or Stop-Limit. See Limit, market and stop-limit orders.
Enter the price (for limit and stop-limit orders) and the Amount or the Total. The slider sets a share of your available balance.
Click Buy or Sell with the asset name.

The funds for the order are reserved and shown as Frozen until the order is filled or cancelled. Orders that are not filled at once appear in Open Orders at the bottom of the page.

If the amount or the total is below the market minimum, the form shows the minimum next to the field.

A fee is charged on every trade: What are the trading fees?

The Help tour button on the Trade page shows what each part of the page does.

Your drawings, indicators and the interval on the chart are saved automatically in this browser, separately for each pair. In another browser, on another device or in a private window the chart opens clean.

The tabs above the chart are the pairs you opened in this browser, the newest on the right. Click a tab to switch to its pair, × to close it. There are at most 12 tabs: opening one more closes the oldest. The tabs are cleared when you log out.

To keep a pair at hand, add it to Favourites: click the star next to the pair name at the top of the page or next to the pair in the market selector. Favourites is the first section of the market selector and the same list as on the Markets page.

To exchange one asset for another quickly without choosing an order type, use Swap.
