Break down the 1300+ line Exchange page into smaller, focused components: - Create useExchangePrice hook - Handles price fetching and auto-refresh logic - Manages price loading and error states - Centralizes price-related state management - Create useAvailableSlots hook - Manages slot fetching and availability checking - Handles date availability state - Fetches availability when entering booking/confirmation steps - Create PriceDisplay component - Displays market price, agreed price, and premium - Shows price update timestamp and stale warnings - Handles loading and error states - Create ExchangeDetailsStep component - Step 1 of wizard: direction, payment method, amount selection - Contains all form logic for trade details - Validates and displays trade summary - Create BookingStep component - Step 2 of wizard: date and slot selection - Shows trade summary card - Handles date availability and existing trade warnings - Create ConfirmationStep component - Step 3 of wizard: final confirmation - Shows compressed booking summary - Displays all trade details for review - Create StepIndicator component - Visual indicator of current wizard step - Shows completed and active steps - Refactor ExchangePage - Reduced from 1300+ lines to ~350 lines - Uses new hooks and components - Maintains all existing functionality - Improved maintainability and testability All frontend tests pass. Linting passes.
