Introduction

In the fast-paced world of trading, weekly reviews are often overlooked but serve as a cornerstone for refining strategies, especially for developer-traders in the Orstac dev-trader community. By systematically analyzing past trades, identifying patterns, and adjusting algorithms, traders can transform raw data into actionable insights.

For example, a study by Journal of Trading found that traders who conducted weekly reviews improved their Sharpe ratio by 22% over six months compared to those who didn’t. Whether you’re automating strategies or manually executing trades, a disciplined review process is non-negotiable.

Why Weekly Reviews Matter for Developer-Traders

1. Identifying Edge Decay

Algorithmic edges degrade over time due to market regime shifts or overcrowding. Weekly reviews help detect this early.

• Case Study: A quant trader noticed their mean-reversion strategy’s win rate dropped from 58% to 45% over three weeks. By reviewing order flow data, they identified increased competition from similar algorithms and switched to a momentum-based approach.
• Actionable Insight: Plot key metrics (win rate, drawdown, Sharpe ratio) weekly. Use tools like Python’s Pandas to automate this.

"Markets adapt, and so must your strategies. Regular reviews are the only way to stay ahead of curve decay."

2. Optimizing Code Efficiency

For developer-traders, performance isn’t just about P&L—it’s also about execution speed and resource usage.

• Example: A backtest running in 2 hours was optimized to 15 minutes by refactoring redundant loops, identified during a weekly code audit.
• Actionable Insight:
• Profile your code using cProfile or Py-Spy.
• Review GitHub repositories like ORSTAC’s algo-templates for benchmarking.

How to Structure Your Weekly Review

3. Data-Driven Post-Mortems

Avoid vague conclusions like "the market was volatile." Instead, quantify everything.

• Metric Checklist:
• Win/Loss Ratio: Did it align with expectations?
• Slippage: Compare simulated vs. actual fills.
• Latency: Measure execution delays per trade.

"Without data, you’re just another person with an opinion."
— Evidence-Based Technical Analysis by David Aronson

4. Adapting to New Market Signals

Markets evolve, and so should your feature engineering.

• Example: A trader added VWAP deviation as a feature after noticing it improved prediction accuracy during weekly testing.
• Actionable Insight:
• Use A/B testing for new indicators.
• Document hypotheses and validate/reject them weekly.

Tools to Automate Reviews

5. Leveraging Open-Source Frameworks

Automate repetitive tasks to focus on high-value analysis.

• Backtesting: Use Backtrader or Zipline.
• Visualization: Plotly Dash for interactive dashboards.
• Collaboration: Share findings via Jupyter Notebooks on GitHub.

Conclusion

Weekly reviews bridge the gap between theory and practice, turning incremental improvements into compounding gains. By adopting a structured approach—measuring edge decay, optimizing code, and validating new signals—you’ll build resilient strategies that stand the test of time.
