# Update Positions

> Add or remove strategy position entries in the vault

# ixWrapperManagerUpdatePosition

Updates the vault's strategy position tracking. Managers use this to register or deregister positions such as orderbook offer indices, token account balances, and Kamino obligation entries. This uses the wrapper instruction which executes via self-CPI. Requires the **manager** role.

## Usage

```typescript theme={null}
import { positionUpdate, priceId } from "@exponent-labs/exponent-sdk/client/vaults";

// Add a Kamino obligation entry
const ix = vault.ixWrapperManagerUpdatePosition({
  manager: wallet.publicKey,
  update: positionUpdate("AddKaminoObligationEntry", [{
    obligationAddress: kaminoObligation,
    lendingMarket: kaminoLendingMarket,
    priceIdDeposit: priceId("Simple", { priceId: 0n }),
    priceIdBorrow: priceId("Simple", { priceId: 1n }),
  }]),
});

const tx = new Transaction().add(ix);
await sendAndConfirmTransaction(connection, tx, [wallet]);
```
