TWAP-ALGO

A TWAP-ALGO order trades based on time intervals to match the Time Weighted Average Price (TWAP) in a security, calculated from the time of order placement to the end of the regular session. TWAP trades strictly on the clock, does not adjust the speed of execution based on historical volume data.

• Algo orders can be routed for listed NYSE, AMEX, NYSE Arca, and Nasdaq stocks.
• Minimum order size is 1,000 shares.
• TWAP-ALGO accepts decimal increments precise to two digits (that is, prices as fine as .01).

• Start time of the order is the time at which it was entered.
• End time of the order is the close of regular session.
• Algo parameters cannot be modified.
