# Taiwan Stock ML Predictor API

FastAPI backend with RandomForest ML model for Taiwan stock prediction (TWSE/TPEX).

## Hugging Face Free CPU Notes

This Docker Space is tuned for Hugging Face CPU Basic:

- `LIGHTWEIGHT_MODE=1`
- `MODEL_MEM_CACHE_SIZE=3`
- `INSTITUTIONAL_FLOW_DAYS=60`
- `INSTITUTIONAL_FLOW_WORKERS=2`
- `WARMUP_STOCKS=""`
- one `uvicorn` worker on port `7860`

These defaults keep cold starts and memory use modest on the free 2 vCPU / 16 GB RAM Space while preserving the 5-day prediction flow. For backtests or accuracy experiments outside the free Space, increase `INSTITUTIONAL_FLOW_DAYS` to `260` and enable warmup stocks explicitly.
