longbridge-fx

Foreign-exchange rates for all currencies Longbridge supports.

Response language: match the user's input language — Simplified Chinese / Traditional Chinese / English.

When to use

• "今天美元兑港币多少", "USD to HKD today" → run, look up USD/HKD row.
• "100 港币能换多少美金" → run, compute 100 / (USD/HKD) (or 100 * (HKD/USD), depending on the row's quote convention).
• "我组合里 HKD / USD / CNY 都有，统一换算成 USD" → run once, normalise each currency leg.
• "人民币兑美元 / CNH vs CNY" → check whether the row is CNY/USD or CNH/USD; surface the symbol verbatim.

For cross-rates not directly listed, derive from two USD-quoted rows (e.g. EUR/JPY = (EUR/USD) / (JPY/USD)).
