One class per provider (TwelveData, Oanda, Tiingo), all subclassing BaseDataProvider which owns cache, validation/cleaning, freshness + boundary guarantees, fetch_range pagination, and streaming stubs — subclasses implement only _fetch_raw. config.json data_providers.active selects the live feed; data_provider.py / oanda_provider.py stay as back-compat shims. Module 16 provider-abstraction tests (253 total green). Claude-Session: https://claude.ai/code/session_01Mc7XKYyPySVXiUpcN82QEK

Per-pair signal producers.

Each pair module exposes:

make_config(primary_tf, confirmation_tfs) -> PlatformConfig
|
|
|
|
To add a new pair: create pair_signals/<pair>.py with make_config(),
|
|
then register it in this file.
