What is NautilusTrader?

NautilusTrader represents Polymarket YES and NO tokens as binary-option instruments and connects them to its event-driven trading framework. The adapter supplies data and execution clients with Python bindings, runtime market loading and reconciliation of orders, fills and positions.

Who it is for

  • Python or Rust teams building event-driven strategies
  • Researchers moving a strategy between replay and live infrastructure
  • Developers who need explicit order-state management

  • Native signing

    Create EIP-712 order signatures in the Rust adapter.

  • Execution

    Submit limit and marketable orders, cancel orders and batch independent limit orders.

  • Reconciliation

    Recover order, fill and position state using active orders, Data API positions and trade history.

  • Resolution handling

    Close winning and losing outcome instruments when the market resolves.

  • Wallet support

    Configure the correct signer, funder and signature type for the account.

Workflows with NautilusTrader

Develop a data strategy

Start with the public data client, load the outcome instruments and process quote or book events. Keep instrument identity consistent in stored research data.

Connect execution

Configure wallet credentials and allowances, then reconcile the account before enabling the strategy. Track cancellations and terminal fills in the same event pipeline.

Pricing and total cost

The adapter belongs to the open-source NautilusTrader platform. Running infrastructure, commercial platform services and venue trading costs are separate.

Getting started

Before you start: Market buys use a quote-currency amount; market sells use share quantities.

  1. Install the supported NautilusTrader release and read its Polymarket integration guide.
  2. Configure a data client and outcome instrument IDs.
  3. Subscribe to a small market set.
  4. For execution, configure signer, funder, signature type and required allowances.
  5. Enable reconciliation before starting the strategy.

What to check

  • Market buys use a quote-currency amount; market sells use share quantities.
  • IOC maps to Polymarket FAK; GTC and GTD apply to resting limits.
  • Venue-native stop, trailing, bracket, OCO and iceberg orders are not supported.
  • Post-only cannot be combined with a market-order time in force.
  • Order changes use cancellation rather than in-place amendment.

Our take on NautilusTrader

A detailed adapter and explicit order-type limitations suit experienced strategy developers. The surrounding platform and venue-specific execution conventions create a substantial learning curve.

Frequently asked questions about NautilusTrader

Can I use market data without credentials?

Yes. Public CLOB feeds and Gamma discovery do not need a wallet.

Does the adapter support Python?

The Rust implementation exposes Python bindings.

Are stop orders venue-native?

No. The documented adapter does not offer venue-native stops or trailing orders.

How are the two outcomes identified?

Each uses a BinaryOption instrument with its condition ID and outcome token ID.
