## Data Sources

- **Binance API**: BTC, ETH, SOL, XRP — 1-minute and 5-minute klines (2 years)
- **Bybit API**: HYPE — 1-minute and 5-minute klines (~11 months, all available)
- **Polygon.io**: SPYX, NVDAX, TSLAX, AAPLX, GOOGLX, XAU — 1-minute and 5-minute aggregates (~2 years)
- **yfinance**: WTIOIL — 5-minute data (~71 days, limited by source)

## Usage

```python
import json

# Load 24h dataset
with open("synth_dataset_24h.jsonl") as f:
    for line in f:
        entry = json.loads(line)
        # entry["real_prices"] has 289 price points at 5-min intervals
        # Use with tune_walk_forward.py, purged_walkforward_backtest.py, etc.
        break
```

## Notes

- Stock tickers map to subnet names: SPY→SPYX, NVDA→NVDAX, TSLA→TSLAX, AAPL→AAPLX, GOOGL→GOOGLX
- Commodity tickers: GC=F→XAU (Gold), CL=F→WTIOIL (Crude Oil)
- All timestamps in UTC
- Prices are from exchange APIs (Binance/Bybit/Polygon/yfinance), not Pyth Network
- WTIOIL 5m data limited to ~71 days — WTIOIL only receives 24h prompts on the subnet
- HYPE data starts from coin launch (~July 2025) — all available history included
