Reproducibility

Reproducibility

This page documents what is (and isn’t) reproducible in indicators-cli, and how to get deterministic runs.

Deterministic profiling (recommended)

Use cached profiling mode:

indicators --profile --profile-mode cached

Cached mode uses a synthetic fixture frame (no network), so repeated runs are comparable.

Live mode variability

Anything that fetches Yahoo Finance data can vary due to:

• upstream availability
• market data revisions
• network latency and transient errors

This affects:

• normal mode runs
• test runs (tests use real data)
• profiling --profile-mode live

Artifact preservation

Profiling artifacts are designed to be reproducible and auditable:

• scenario definitions (profiling/scenarios.json)
• environment snapshot (Python/OS/Polars version)
• cProfile dumps (profiling/results/raw/*.prof)
• generated output files (profiling/results/raw/<run_id>/...)

See Profiling Artifacts.
