# Replace position

Replace lets you restructure an entire position in one action: switch side, resize, adjust margin and leverage.

Steps:

1. Tap your open position.
2. Tap the menu at the bottom left
3. Tap Replace position.
4. Configure the new position: side, size, margin, leverage.
5. Confirm. The old position closes and the new one opens in a single transaction.

Faster and cheaper than closing manually and re-opening, especially when the market moves fast.

This feature doesn’t exist on Hyperliquid — we built it from scratch. To reproduce it there, you would need to close your position and reopen a new one. If that’s required, a message will be displayed informing you that your current position will be closed and a new one opened. This also means you’ll pay fees twice and your PnL will be reset.
