about

nx_fin_marketdata_fetch.nx -- MAKE IT REAL: the live ingestion adapter + end-to-end demo. Fetches a symbol's daily OHLCV from Alpha Vantage (CSV) over the SOVEREIGN TLS fetcher (no curl), parses via md_parse_csv, reverses to chronological order (Alpha Vantage returns newest-first), then runs the ENTIRE pipeline on REAL data: ADV/capacity (R1) -> SMA signals (R3) -> backtest with slippage + ADV cap (R2) -> honest metrics. This proves the whole stack on real market data -- SIM ONLY, no live capital. The API key is DATA (Cardinal 11/17: env/config > default "demo"); the demo key serves IBM. Composes the proven fetch + the fin_* organs. license_tier: ORIGINAL
