# Position Vault

**Initialize**

This function initializes the contract with the operators, vlp, and vusd addresses.

```solidity
function initialize(address _operators, address _vlp, address _vusd) public {
    __ReentrancyGuard_init();
    operators = IOperators(_operators);
    vlp = IVLP(_vlp);
    vusd = IVUSD(_vusd);
}
```

**NewPositionOrder**

This function allows the vault to create a new position order.

```solidity
function newPositionOrder(
    address _account,
    uint256 _tokenId,
    bool _isLong,
    OrderType _orderType,
    uint256[] memory _params,
    address _refer
)
```

**AddOrRemoveCollateral**

This function allows the vault to add or remove collateral from a position.

```solidity
function addOrRemoveCollateral(
    address _account,
    uint256 _posId,
    bool isPlus,
    uint256 _amount
)
```

**CreateAddPositionOrder**

This function allows the vault to create an order to add to a position.

```solidity
function createAddPositionOrder(
    address _account,
    uint256 _posId,
    uint256 _collateralDelta,
    uint256 _sizeDelta,
    uint256 _allowedPrice
)
```

**CreateDecreasePositionOrder**

This function allows the vault to create an order to decrease a position.

```solidity
function createDecreasePositionOrder(
    uint256 _posId,
    address _account,
    uint256 _sizeDelta,
    uint256 _allowedPrice
)
```

**SelfExecuteDecreasePositionOrder**

This function allows users to self-execute a decrease position order after the selfExecuteCooldown period has passed.

```solidity
function selfExecuteDecreasePositionOrder(uint256 _posId)
```

**ExecuteRemoveCollateral**

This function allows the vault to execute the removal of collateral from a position.

```solidity
function executeRemoveCollateral(uint256 _posId)
```

**ExecuteOpenMarketOrder**

This function allows the vault to execute an open market order.

```solidity
function executeOpenMarketOrder(uint256 _posId)
```

**ExecuteAddPositionOrder**

This function allows the vault to execute an add position order.

```solidity
function executeAddPositionOrder(uint256 _posId)
```

**ExecuteDecreasePositionOrder**

This function allows the vault to execute a decrease position order.

```solidity
function executeDecreasePositionOrder(uint256 _posId)
```

**ExecuteOrders**

This function allows the vault to execute a batch of orders also this function executes a batch of orders. The `numOfOrders` parameter specifies the number of orders to execute. The `onlyOperator(1)` modifier ensures that only an operator with level 1 can call this function.

```solidity
function executeOrders(uint256 numOfOrders)
```

**IncreasePosition**

This function is called by the Order Vault contract to increase a position.

```solidity
function increasePosition(
    uint256 _posId,
    address _account,
    uint256 _tokenId,
    bool _isLong,
    uint256 _price,
    uint256 _collateralDelta,
    uint256 _sizeDelta,
    uint256 _fee
)
```

**DecreasePosition**

This function is called by the Vault contract to decrease a position.

```solidity
function decreasePosition(
    uint256 _posId,
    uint256 _price,
    uint256 _sizeDelta
)
```

**DecreasePositionByOrderVault**

This function is called by the Order Vault contract to decrease a position.

```solidity
function decreasePositionByOrderVault(
    uint256 _posId,
    uint256 _price,
    uint256 _sizeDelta
)
```
