# Adding Margin to an Open Position
Kana Labs’ perpetual futures trading platform uses the Isolated Margin system. This risk-managed approach ensures that only the margin allocated to a specific position is at risk, regardless of the total balance in the trader’s account. It protects users from losing their entire account balance due to adverse price movements in a single trade. However, traders must actively monitor their positions and add margin when necessary to prevent liquidation and maintain a healthy margin buffer
### Step by Step Guide -
**Step 1**— To add margin to an open position, navigate to the “Positions” tab. Locate the active trade for which you wish to increase margin and click the “Add” button, denoted by a pencil icon.
**Step 2**—A pop-up window will appear, allowing you to input the additional margin amount. Note that the additional margin must be less than or equal to the current margin amount displayed in the Positions tab. For example, if the current margin is $1.60, you may add up to $1.60 or any amount below it. In this case, $1.39 is added as additional margin. Once the margin has been updated a notification stating “Margin Added Successfully” will appear on the screen.
