22## When to use
23 
24Trigger on prompts asking about:
25 
26- ADR vs H-share premium / discount — *"BABA ADR 溢价"*, *"百度 ADR 和港股哪个便宜"*
27- Three-market comparison — *"BABA.US / 9988.HK / 阿里A股 比价"*
28- Theoretical arbitrage spread and constraints — *"ADR 套利空间"*, *"ADR arbitrage"*
29- Dual-listing pricing discrepancy — *"dual-listed premium"*, *"跨市场套利"*
30 
31For pure A/H premium time series defer to `longbridge-ah-premium`.
32 
33## Workflow
34 
351. Identify all available listing venues for the company (ADR ticker, HK code, A-share code).
362. Fetch real-time quotes for each venue.
373. Fetch USD/HKD and USD/CNY exchange rates.
384. Convert all prices to a common currency (USD) using the ADR ratio where applicable.
395. Calculate premium / discount between each pair: `(Price_A − Price_B) / Price_B × 100%`.
406. Assess arbitrage constraints: FX repatriation rules, stamp duty, liquidity depth, settlement lag.
417. Output a comparison table and narrative.
42 
43> If unsure of exact flag names, run `longbridge <subcommand> --help` before proceeding.
44 
45## CLI
46 
47```bash
48# Quotes for each listing venue
49longbridge quote <ADR_SYMBOL> --format json
50longbridge quote <HK_SYMBOL> --format json
51longbridge quote <A_SYMBOL> --format json   # omit if no A-share listing
52 
53# Exchange rates for currency conversion
54longbridge exchange-rate --format json
55```

70```
71Symbol        Price (local)   Price (USD)   vs ADR
72──────────────────────────────────────────────────
73BABA.US        $82.50          $82.50        baseline
749988.HK        HK$638.00       $81.79        −0.9%
75```

77Then explain:
78- Which venue is cheapest / most expensive and why.
79- Arbitrage constraints (FX controls, transaction costs, liquidity).
