VWAP (Volume-Weighted Average Price) orders are supported for large cap securities only. You can also use the non-guaranteed VWAP Algo.
To create a VWAP order
By default, the VWAP is computed from the soonest cut-off time to the market close. To change, click the Time Entry calendar icon to select a new VWAP cut-off, or start, time. If none is selected, the soonest cut-off is used. In addition, you can modify the end time of the calculation using the Expiry Time field.
A transmitted VWAP order is accepted immediately and CANNOT BE CANCELLED.
VWAP orders are automatically routed.
