longbridge-ah-premium

A/H premium ratio for dual-listed Mainland-Chinese companies — historical kline or today's intraday curve.

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

When to use

Trigger when the user asks about the price gap between an HK listing and its A-share twin:

"工行 A/H 溢价", "工行 AH 比价" →
```
1398.HK
```
"建行 AH 折价" →
```
939.HK
```
"中国平安港股比 A 股贵多少" →
```
2318.HK
```
"AH premium for ICBC over the last year" →
```
1398.HK --kline-type day --count 250
```
"今天 939 的 AH 溢价走势" →
```
intraday 939.HK
```

For single-symbol quote, use

longbridge-quote

. For comparison of unrelated tickers, use

longbridge-peer-comparison

.

Symbol format

Always pass the HK side (

<CODE>.HK

) of the dual-listed pair. The Longbridge API maps internally to the A-share counterpart. Common pairs:

Company	HK	A-share
工商银行 / ICBC	`1398.HK`	`601398.SH`
建设银行 / CCB	`939.HK`	`601939.SH`
中国平安 / Ping An	`2318.HK`	`601318.SH`
招商银行 / CMB	`3968.HK`	`600036.SH`
中国人寿 / China Life	`2628.HK`	`601628.SH`

If the user gives an A-share symbol, translate to the HK side. If the stock is not dual-listed (e.g.

700.HK

), the API returns no data — report that, don't retry.

CLI examples

bash

# Default daily kline (100 days)
longbridge ah-premium 939.HK                                       --format json

# Last year of daily premium
longbridge ah-premium 1398.HK --kline-type day --count 250         --format json

# Last 12 weeks
longbridge ah-premium 2318.HK --kline-type week --count 12         --format json

# Today's intraday premium curve
longbridge ah-premium intraday 939.HK                              --format json

Output

Each row carries a timestamp and a premium ratio (typically expressed as

(H_price * fx) / A_price - 1

, in %). Negative = HK trades at a discount to A-share. Surface latest value + recent range.

Error handling

Situation	LLM response
Shell `command not found: longbridge`	Fall back to MCP if configured; otherwise tell the user to install longbridge-terminal.
Empty array	"No A/H premium data — `<SYMBOL>` is likely not dual-listed in A-shares."
stderr `param_error`	Verify the symbol is an HK ticker of a dual-listed pair.
Other stderr	Surface verbatim.

MCP fallback

CLI subcommand	MCP tool
`ah-premium <SYMBOL>` (kline)	`mcp__longbridge__ah_premium_kline` (or fall back via the equivalent MCP tool)
`ah-premium intraday <SYMBOL>`	`mcp__longbridge__ah_premium_intraday` (or fall back via the equivalent MCP tool)
