Lesson 8: 15.8: Building Sentiment-Driven Algorithmic Strategies & Risk Rules
Construct systematic sentiment trading models, stop-loss governance, sentiment regime filters, and backtesting.
1. Designing a Sentiment Strategy Architecture
A production sentiment strategy combines alternative sentiment data with quantitative technical filters.
1. Entry Triggers: Go long when sentiment z-score exceeds +2.0 alongside positive price momentum; go short or exit when sentiment breaks below -1.5.
2. Regime Switching: Use macro VIX term structure to scale down position sizing during high-volatility panic regimes.
★ Dynamic Stop-Loss Governance: Incorporate volatility-adjusted ATR trailing stops to prevent premature shakeouts while protecting against sentiment reversal crashes.
2. Backtesting and Robustness Audits
Quant models must account for point-in-time alternative data availability, lookahead bias, and transaction costs to ensure realistic live performance.
