How do you design AngularJS for high-frequency real-time financial trading systems?

High-frequency AngularJS UIs require throttled updates, WebSocket batching, and minimal digest triggers.

Financial trading systems push updates at extremely high frequency, which can overwhelm AngularJS digest cycles. To handle this, updates are batched using $applyAsync, and WebSocket streams are throttled. UI components are isolated to prevent global digest execution. Critical optimization includes avoiding deep watches and using immutable data updates.
