TradingAPI

Brokers building the securities UI in their Broker App from scratch combine WhaleCore SDK with TradingAPI.

• WhaleCore SDK is the UI-free data layer in the Whale SDK product family. It provides market data subscriptions, WebSocket connectivity, request signing, and token renewal.
• TradingAPI is a client-scoped HTTP API for account, asset, trading, and related business capabilities.

• You need complete control over information architecture, visual design, and interactions.
• You already maintain market data, asset, and trading screens and do not want to embed Whale-provided UI.
• You are prepared to combine data streams, HTTP operations, page state, and error recovery.

Use WhaleApp SDK instead when you want a complete trading UI for iOS, Android, or WebTrade.
