When & Why to Use This Skill

This Claude skill streamlines the development and integration of custom Python-based technical indicators within the AERA platform. It provides a structured framework for creating indicator scripts, ensuring adherence to Plot API v1 standards, and automating the deployment process in the Strategy Lab environment for financial data analysis.

Use Cases

  • Developing custom technical analysis indicators (e.g., specialized RSI or moving average variants) using Python scripts.
  • Standardizing the creation of new financial metrics to ensure seamless compatibility with AERA's backend registry and frontend rendering.
  • Automating the boilerplate setup for indicator scripts, including input declarations and Plot API output formatting.
  • Verifying and debugging new indicators through integrated terminal commands and real-time chart testing within the Strategy Lab.

Create New Indicator (Python)

Use when adding a new indicator under the Strategy Lab indicators/ workspace.

Constraints (platform rules)

  • Do NOT hardcode indicator id/name/kind in the frontend renderer.
  • Keep the output generic via Plot API (v1 today).

Steps

  1. Create the script file
  • Path: server/indicators/<name>.py (or subfolders under server/indicators/).
  • Must export calculate(inputs, settings=None).
  • Optional: initialize(ctx) to declare Inputs UI (Manifest).
  1. Produce Plot API v1 output (recommended)
  • Return {"plots": [...]}.
  • Prefer index-based coordinates (index, from/to) so the backend can align to candle time.
  • Reference: docs/public/plot-api-v1.md.
  1. No manual registration
  • The backend scans server/indicators/ automatically:
    • server/src/services/indicatorFileService.js
    • server/src/indicatorRegistry/registry.js
  • The indicator id is the relative path including .py (example: my_indicator.py or market_structure/pivots.py).
  1. Verify
  • In the app: Strategy Lab -> save the file; Chart -> activate and run.
  • Optional quick check: Debug -> terminal command run indicator <id> --asset=CL1! --tf=M15 --len=1000.
  • Run standard validations: see skills/verify_changes/SKILL.md.
