You have a great alpha signal. Your backtests look amazing. Then you trade it live and the performance disappears. Welcome to execution - where 50% of alpha dies. A quant trader who understands execution is worth their weight in gold. Here's how to hire one.

Execution Algorithms Every Quant Trader Must Know

Non-negotiable knowledge:

✦ VWAP (Volume-Weighted Average Price) - benchmark and algo
✦ TWAP (Time-Weighted Average Price) - simple but effective
✦ Implementation Shortfall - minimizing slippage from decision to execution
✦ POV (Percentage of Volume) - trading at a fixed percentage of market volume
✦ IS (Implementation Shortfall) algos - balancing urgency with market impact

Execution Systems Experience

Look for experience with:

✦ Order management systems
✦ Execution management systems
✦ Exchange connectivity
✦ Real-time monitoring
✦ Post-trade analytics

Interview Questions That Test Execution Expertise

Great answer: Assess urgency. For low urgency, use VWAP or POV. For high urgency, use IS algo. Consider time of day, volatility, and liquidity profile.

Look for references to Kyle's lambda, Almgren-Chriss framework, or empirical models. Senior candidates have measured impact on their own trades.

TWAP ignores volume - trades evenly over time. VWAP matches volume profile. Use TWAP for low-volume periods or when volume forecast is unreliable. Use VWAP when you trust volume predictions.

Red Flags in Execution Quant Traders

Walk away if they:

✦ Only know VWAP (no TWAP, IS, or POV knowledge)
✦ Can't explain how market impact affects P&L
✦ Have never traded during volatile market conditions
✦ Don't understand exchange fee structures and rebates
✦ Have no experience with real-time monitoring of executions

Beyond Algorithms: Implementation Skills

Great execution quant traders also understand:

✦ Smart order routing - which exchange gets your order?
✦ Liquidity-taking vs liquidity-providing strategies
✦ Post-trade analysis - did you execute well?
✦ Real-time adjustment - algos aren't set-and-forget
✦ Broker algos vs building your own

Execution Trader Verification Checklist

Verify candidate can demonstrate:

✦ Live execution experience
✦ Slippage analysis capability
✦ Market impact understanding
✦ Risk control implementation
✦ Production trading system exposure

Hire Execution Experts

A quant trader who can't execute isn't a quant trader. They're a researcher with a backtest. Offline Pixel pre-vets execution expertise before you ever see a resume. Raise a request, talk to quant traders who have shipped real execution systems, fund the project, and approve payment when the work is done.
