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)
).

Subcommand

Single CLI command, no arguments beyond format. Run 
longbridge exchange-rate --help
if unsure of current flags.
bash
longbridge exchange-rate --format json
There are no per-currency filters — the command returns the full table; pick the row(s) you need from the JSON.

Workflow

  1. Run 
    longbridge exchange-rate --format json
    .
  2. Find the row matching the user's pair (mind the quote convention: 
    BASE/QUOTE
    is "1 BASE = N QUOTE").
  3. If user wants a specific amount, do the arithmetic inline; show both rate and computed amount.
  4. If the user's pair isn't directly quoted, derive via USD: 
    A/B = (A/USD) / (B/USD)
    .
  5. Cite source as Longbridge Securities / 数据来源:长桥证券 / 數據來源:長橋證券, plus the as-of timestamp from the response if provided.

CLI examples

bash
# Full rate table
longbridge exchange-rate --format json
That's it — there's no symbol argument. Filter on the JSON client-side.

Output

JSON array, one row per supported pair. Typical fields:
FieldMeaning
symbol
/ 
pair
e.g. 
USD/HKD
, 
CNY/USD
rate
numeric exchange rate
timestamp
as-of time
Render the relevant row(s) only; don't dump the full table unless the user asked for it.
