Adding Value to Systematic Trading:
Where the Human Edge Matters
A great question from the Stats Edge Pro community inspired this discussion: Where can traders add value to a trading system without undermining its structure?
Key Takeaways:
Stock Selection:
Traders can refine their system’s outputs by filtering trades that don’t align with their portfolio, risk tolerance, or market view.
For example, avoiding overly volatile names like Carvana or steering clear of trades that overexpose you to a specific sector.
Order Entry:
Human intuition can identify whether there is support or resistance at a system's trigger price.
Example: Waiting for confirmation of strength before entering a trade slightly above the system’s signal price.
Exits:
Flexibility in exits can add value by extending winners or cutting losers earlier.
Example: Holding HCA for an extra day when the setup showed continued strength, leading to a better exit than the system prescribed.
The Benchmarking Process:
Tracking your trades against the system’s theoretical performance is crucial. It allows you to determine whether your discretionary adjustments improve or hinder results.
If you outperform the system, continue making small tweaks.
If you underperform, lean more heavily on the system and reduce discretionary inputs.
Mindset Shift:
Stop equating profitability with success or losses with failure. Instead, focus on whether your decisions outperformed the system’s baseline. This mindset helps you stay consistent during drawdowns and ensures long-term improvement.
