custom-indicator

Create a custom technical indicator by composing openalgo's Rust-core ta primitives with vectorized NumPy.

Arguments

• $0 = indicator name (e.g., zscore, squeeze, vwap-bands, custom-rsi, mean-reversion). Required.

If no arguments, ask the user what indicator they want to build.

Instructions

1. Read the indicator-expert rules, especially:
   • rules/custom-indicators.md — NumPy + ta-primitive patterns and templates
   • rules/performance.md — Rust core performance, O(n) guarantees, benchmarking
   • rules/indicator-catalog.md — Check if indicator already exists in openalgo.ta
2. Check first: If the indicator already exists in openalgo.ta (100+ indicators), tell the user and show the existing API
3. Create custom_indicators/{indicator_name}/ directory (on-demand)
4. Create {indicator_name}.py with:
