"""Populate the shared data store the examples read. Not an example itself.

Twenty of the files here are marked `Data: shared store`: they read real
market data from `data/` + `metadata/`, which are not in the repository
because market data does not belong in a git repository. This script
downloads what those files name, once.

    python examples/setup_data.py            # everything, ~10 symbols
    python examples/setup_data.py BTC        # just the symbols an ID matches

Everything is ingested at 1h. The engine aggregates upwards, so one 1h store
serves every example here, including the ones running on 12h or daily bars.

The connectors used (binance, dydx) are free on all tiers and need no API key.
Re-running is safe: an interval already present is not downloaded twice.

Usage:
    python examples/setup_data.py
