HFT FUTURES
TRADING.

The contract is the unit of truth

An executable futures order must identify an actual contract. Keep expiry, quotation convention, price increment, quantity increment, and payoff parameters with the venue identifier. A continuous historical series is useful for analysis but cannot replace the contract definition used for order entry.

Use tested units, not remembered multipliers

Calculate exposure from the current approved instrument record. The full article includes a fictional tick-value calculation to show the method without presenting invented product specifications. Reject incomplete reference data rather than silently importing the settings of a similar contract.

Review sessions, collateral, and rolls

Ask how the provider represents session transitions and how outstanding instructions are reconciled. Keep account margin information separate from notional and modeled exposure. A roll between expiries is a workflow with possible partial outcomes, not merely a symbol substitution.

A useful first experiment

Create a contract-specific replay with a mismatched increment, a session interruption, and an incomplete roll. Verify the exact remaining contracts and reservations after each event. Then compare the local account view with the supported authoritative records before permitting another action.

Build a connected reading path

Continue with the complete futures field guide, which includes a primary reference and practical test scenarios. Use the architecture blueprint for the shared system model and the risk checklist for permission and recovery. Confirm actual product terms with the relevant provider before any implementation.
