Connect a broker

To trade live, connect a brokerage or exchange account. Backtesting does not require a connected broker.

Supported integrations

Horizon supports a growing list of brokers and exchanges. See the current list on Supported brokers and the Brokers page.

Connection methods

Depending on the broker, you'll connect with one of:

• Login - sign in to the broker through its secure hosted portal
• OAuth - authorize Horizon directly from the broker
• API key - generated in your broker account
• API wallet - for on-chain venues such as Hyperliquid

Next steps

Once connected, review Going live before deploying a strategy with real capital.
