VWAP and TWAP Algos Complete Configuration

Algorithm Overview:


VWAP (Volume Weighted Average Price):

Definition: VWAP and TWAP Algos are supported via Instinet.

Calculation Method: Weighted average price based on volume throughout the trading day.

Execution Strategy: Breaks large orders into smaller pieces to match historical volume patterns.

Market Impact: Minimizes market impact by following natural volume distribution.

Benchmark: Provides execution close to the day's volume-weighted average price.

Time Horizon: Executes throughout the trading session based on historical volume curves.

TWAP (Time Weighted Average Price):

Definition: Time-based algorithmic execution strategy via Instinet.

Execution Method: Evenly distributes order quantity across specified time period.

Time Distribution: Equal time slices regardless of volume patterns.

Predictability: More predictable execution schedule compared to VWAP.

Market Participation: Consistent market participation throughout execution period.

Strategy Focus: Time-based rather than volume-based execution.

Complete Configuration Procedures:

Standard Order Entry:


  • Type Dropdown Access: Select VWAP or TWAP from the Type dropdown in your Order Entry Window.


  • Access Requirements: If you do not have the Type available contact your Relationship Manager for Access.


  • Order Validation: System validates algorithm parameters before submission.


  • Real-time Monitoring: Continuous monitoring of algorithm performance.


  • Execution Reporting: Detailed reporting of algorithm execution statistics.

Start/End Time Behavior:


  • Important Note: Note: There is no start time/end time field. On all orders, the start time is the time the order is sent, the end time is the close.


  • Automatic Timing: Start time automatically set to order submission time.


  • End Time Default: End time automatically set to market close (4:00 PM ET).


  • Session Management: Algorithms manage execution across entire remaining trading session.


  • No Custom Timing: Cannot specify custom start or end times within the trading day.


  • Market Hours: Execution limited to regular trading hours (9:30 AM - 4:00 PM ET).

Instinet Platform Integration:

Instinet Algorithm Engine:


  • Provider: Algorithms executed through Instinet's sophisticated algorithm engine.


  • Market Access: Access to Instinet's extensive liquidity network.


  • Execution Quality: Institutional-grade execution quality and reporting.
