The netOpenQuantity method is used to determine the net open quantities of a position. The default behavior is that each position will have its own quantities tracked independently of another position, even when one position offsets / closes the legs of another position.
But if the consideredPositionsClosedIfOffsetByIndependentPositions setting is used, the netOpenQuantity method will include offsetting positions from other trades.
Time 1: OrderID=”BuyCallVertical1″
- Buy 10x Call, Strike = 100
- Sell 10x Call, Strike = 110
Time 2: OrderID = “SellCallVertical1”
- Sell 10x Call, Strike = 100
- Buy 10x Call, Strike = 110
By default, the netOpenQuantity will be 10 for both orders, as each position will be tracked independently of another.
If the consideredPositionsClosedIfOffsetByIndependentPositions is used, the netOpenQuantity will be zero for both orders, as the SellVertical1 order offsets / closes the BuyCallVertical1 order.
The netOpenQuantity will be the number of open contracts in the lowest ratio leg of a position.
- 10 x (Call Vertical) = 10
- 10 x (standard butterfly) = 10
- 10 x (2 x 3 put ratio) = 20
- 10 x (3 x 4 call ratio) = 30
- 10 x (2x5x3 unbalanced butterfly) = 20
