Workflow Patterns

Viewing Portfolio

1. Load data via data-store.ts load
2. Find current portfolio by currentPortfolioId
3. Calculate total value using quantity * currentPrice per asset
4. Convert to display currency using exchangeRates
5. Present as a formatted table

Adding Assets

1. Load data
2. Search for the asset using fetch-prices.ts search <query>
3. Get current price via fetch-prices.ts crypto/stock <symbol>
4. Add asset to current portfolio with a generated unique ID
5. Save data

Refreshing Prices

1. Load data
2. Pipe current portfolio assets to fetch-prices.ts refresh via stdin
3. Also run fetch-prices.ts fx for exchange rates
4. Update each asset's currentPrice and the exchangeRates
5. Set lastPriceRefresh to current ISO timestamp
6. Save data

Syncing from Exchange/Wallet

1. Load config to get credentials
2. Run the appropriate sync script
3. Merge results: update existing assets (match by symbol+source), add new ones
4. Save data
