Trade Bybit with NautilusTrader

Four product types

Spot, linear, inverse, and options, each enabled per client and reached from a single Unified Trading Account with cross, isolated, or portfolio margin.

HMAC-SHA256 signing

An API key and secret sign every REST and WebSocket request, handled in the Rust core rather than through an external Bybit SDK.

Data and execution

One adapter covers both market data and order execution, with order, fill, position, and balance reconciliation.

Hedge and one-way modes

USDT linear perpetuals run one-way or hedged per symbol, with long and short venue position IDs derived from the order side.

Option greeks and chains

Delta, gamma, vega, theta, and implied volatility stream per contract, aggregated into option chain snapshots with ATM-relative strike filtering.

Mainnet, demo, and testnet

Select the environment with one config enum across mainnet, demo trading on mainnet infrastructure, and the separate testnet, each with its own credentials.

Post-only

Maker-only limit orders across all four product types, rejected by the venue if they would cross the book.

Reduce-only

Position-reducing flag on linear, inverse, and option orders; spot has no venue-side position to reduce.

Order modification

Amend price and quantity on resting orders in place, without a cancel-and-replace round trip, singly or in batches.

Native TP/SL

Attach take-profit and stop-loss levels to an order, each with its own trigger source, market or limit execution, and limit price.

BBO orders

Linear and inverse limit orders delegate price selection to the exchange, pegged to a queue or counterparty book level.

Spot margin borrow and repay

Borrow, repay, and query balances from a strategy, with automatic repayment after closing a short so borrows stop accruing interest.
