Create Strategy (LEAN QCAlgorithm)

Use when adding a new strategy under the Strategy Lab strategies/ workspace.

Steps

  1. Create the strategy file
  • Path: server/​strategies/<StrategyName>.py
  • Must define a QCAlgorithm class with Initialize and OnData.
  1. Use AERA-injected parameters
  • Read with GetParameter(...) and provide safe defaults:
    • symbol, resolution, cash, feeBps, slippageBps
  1. Keep it LEAN-safe
  • No network I/​O.
  • Avoid writing files from the algorithm.
  • Keep logs short (no spam).
  1. Verify
  • Run from the app: Strategy Lab -> Run (LEAN) and inspect job logs/​results.
  • Run standard validations: see skills/​verify_changes/​SKILL.md.
