# Bridge Brokerage and Market Data APIs

When ingesting brokerage data (e.g., Fidelity CSV) and fetching live prices from market APIs (e.g., Yahoo Finance), ticker symbols often differ. Create a centralized `TICKER_MAP` dict to alias brokerage symbols to API symbols (e.g., `BRKB → BRK-B`). Also extend API queries with a longer period window (e.g., `5d` instead of `1d`) to handle weekends/holidays returning empty data. Apply the mapping at the ingest layer before price-fetch calls.
