Performance

What usually dominates runtime

1. Data download (network + upstream latency)
2. Indicator computation (rolling windows, ewm)
3. File writing (especially CSV and XLSX)

Practical guidance

Prefer Parquet for analytics

indicators AAPL -f parquet

Use coarser intervals for long horizons

indicators AAPL -p 10y -t 1mo

Batch tickers efficiently

indicators AAPL MSFT NVDA -f parquet -d ./output

Profiling

Use cached profiling mode for deterministic benchmarks:

indicators --profile --profile-mode cached
