TWAP VWAP Quant Interview Guide
TWAP VWAP quant interview guide covering time-weighted execution, volume-weighted execution, participation, benchmarks, tradeoffs, and mistakes.
Candidates discussing benchmark execution and simple slicing algorithms.
TWAP slices by time
A TWAP algorithm spreads an order across time intervals, which is simple and predictable but may ignore actual liquidity patterns.
VWAP follows volume distribution
A VWAP algorithm tries to match expected or realized market volume, making it sensitive to volume-curve estimates and benchmark choice.
Concrete example
A stock with heavy open and close volume may suit a VWAP schedule better than equal-sized trades every hour, if VWAP is the target.
Benchmarks are not objectives by themselves
A benchmark algorithm is useful only when the benchmark reflects the trader objective, risk tolerance, and order constraints.
Common mistakes
Candidates often say VWAP is better than TWAP. The right schedule depends on urgency, liquidity, alpha decay, and benchmark incentives.
