From Main Menu, click Dashboard.
Click the SPOT at the top right of the page to switch to spot market.
In the panel on the left of the page, click Stop.
Choose your price and quantity. Note that a stop order is the opposite of the limit order, meaning the price must be higher than market price for a stop buy order, and vice versa for a stop sell order.
Click Buy or Sell to submit.
A popup confirmation will ask you to confirm the order you are about to make. Click Confirm to agree that you will place this order, or Dismiss to stop the action. If you click Confirm, the next popup will confirm that the order has been placed successfully. Click Dismiss again.
You can monitor your orders in the Orders panel (under the chart if using horizontal layout, or right to the chart if using vertical layout).
