# Fetch ticker
ticker = exchange.fetch_ticker("ETH/USDT")
print(f"ETH price: {ticker['last']}")

CCXT uses slash format: BTC/USDT, ETH/BTC, SOL/USDT
The project's DataLoader automatically converts BTC-USDT (hyphen) to BTC/USDT (slash).
Set via environment variable: CCXT_EXCHANGE=binance (default)
Popular exchanges: binance, bybit, okx, coinbase, kraken, bitget, gate
The project has a built-in CCXT DataLoader at backtest/loaders/ccxt_loader.py. It serves as a fallback when the OKX loader is unavailable.
For long history, CCXT paginates via the since parameter (millisecond timestamp). The built-in loader handles this automatically (up to 200 pages).
