NIFTY 50 Forecaster Backend

FastAPI Hugging Face Docker Space for the NIFTY 50 first-five-minute direction forecaster.

Endpoints

• GET /health
• GET /dashboard
• GET /prediction/latest
• POST /prediction/refresh-first5
• POST /data/refresh-daily
• GET /cron/keepalive
• POST /data/refresh-market-close

Data

Parquet files live in data/:

• nifty50_1m.parquet
• nifty50_1d.parquet
• opening_direction_training_dataset.parquet
• test_predictions.parquet

Runtime

The API starts a daily background refresh loop. It wakes after 09:20 Asia/Kolkata, fetches Yahoo Finance ^NSEI 1-minute candles for the 09:15-09:19 opening window, appends them to Parquet, and writes the latest T+5 prediction.

After market close it wakes again at 15:45 Asia/Kolkata, refreshes the 1-minute and daily Parquet files, updates the opening training dataset with same-day close outcomes, and writes the saved prediction record used for the next trading session card. The /cron/keepalive endpoint also checks this close refresh so a Hugging Face Space that was idled still catches up when Netlify pings it.

Netlify also pings /cron/keepalive every 10 minutes through its scheduled function.
