Execution quality determines how closely real results match trade intent. On the Gold path it is a central metric of operational competitive advantage.
Who this is for
- Traders who want to measure the hidden cost of execution.
- Those optimising systems with thin edge.
- Those managing significant volume across different venues.
In plain terms — Entering and exiting is not enough: how you get filled matters. Small recurring degradations destroy expectancy over time.
Prerequisites — Complete first silver-path (min.: market-order, slippage, active-management, position-sizing). Foundation: bronze-path.
Measurement framework
Compare executed price with coherent benchmarks: mid, arrival price, VWAP. Break cost into spread, slippage, market impact, and latency. Segment analysis by time, instrument, order type, and size. Define acceptable thresholds and workflow review triggers. Use periodic reports to correct processes and venue selection.
Example — A profitable backtested strategy loses 0.15% per trade live. Analysis shows high slippage on market orders at the open. Switching to split execution reduces average cost steadily.
Card
- Objective: reduce friction between decision and execution.
- Key inputs: price benchmark, order log, implicit costs.
- Alert signal: growing backtest vs live divergence.
- Typical mistake: measuring only explicit commissions.
- Practical action: monthly review by instrument and venue.
