Trading Lifecycle

This guide walks through the end-to-end operational workflow for external API clients connecting to the Atomic Vaults platform. The lifecycle is divided into three phases: Pre-Trade, Trade Execution, and Post-Trade & Settlement.

Phases​

Phase 1: Pre-Trade​

Customer account onboarding, cash balance auditing, SOD transaction verification (corporate actions, stock transfers), margin calculations, instrument reference data discovery, overnight option quote/trade snapshots (US only), and real-time WebSocket subscriptions.

Phase 2: Trade Execution​

Order placement for single-leg and multi-leg option strategies, order status monitoring, order modifications, and cancellations.

Phase 3: Post-Trade & Settlement​

Position tracking, ledger auditing, subaccount transfers, and Free-of-Payment (FOP) transfers.

Authentication​

note

All REST requests require authentication via the X-API-KEY header. Most pre-trade and post-trade endpoints also require an account_number parameter. See the Authentication guide for details.
