Bybit

Capabilities

• Backfill: OHLC (full), order-book snapshot. No trades.

• Stream: OHLC, trades, order book.

• OHLC fidelity: quote_volume ✅ native · trades — null.

Note

Bybit spot exposes only the ~60 most recent trades and no history, so trades backfill raises NoCapability rather than returning a misleading recent slice. Live trades are available via the stream.

Symbols

BTCUSDT (no separator), spot category.

Example

async with Client() as c:
    await c.backfill("bybit", "BTC/USDT", "ohlc", span=3600, start="2024-01-01")

API

class BybitSource(http=None)

Bybit source adapter (spot).

• Backfill: OHLC (full), order-book snapshot. No trades (see Notes).

• Stream: OHLC, trades, order book.

Notes

Bybit spot exposes only the ~60 most recent trades and no history, so TradesHistory is deliberately not implemented — a trades backfill raises NoCapability rather than returning a misleading recent slice. Live trades are still available via the stream.

>>> from dccd.sources.bybit import BybitSource
