Direzione di ricerca

Start by reading the IPO detail CLI/API documentation and tracing which endpoint supplies sub_multiple, margin_multiple, and margin_sub. Check whether the API documents permissions or quote levels for subscription-period data, and whether it exposes historical allotment results. Done means the documentation or API behavior answers the three questions with a reproducible source for the values.

Descrizione

Hello,

Longbridge Customer Service ([email protected]) directed me here for this OpenAPI question.

I use the official Longbridge CLI to query Hong Kong IPOs that are currently in their subscription period, e.g.:

longbridge ipo detail 7672.HK

Observation: the fields sub_multiple, margin_multiple and margin_sub are always empty strings throughout the entire subscription period — including on the last day before the subscription deadline. I have verified this repeatedly across multiple IPOs and at multiple stages of their subscription periods (for example, 7672.HK on the 5th day of its subscription period, one day before its deadline, still returned empty strings for all three fields).

Meanwhile, the Longbridge App shows an estimated subscription multiple for the same IPO on its subscription page, so an estimate does exist on the platform — it just does not seem to be exposed via CLI/API.

Questions:

  1. Are the estimated subscription multiples intentionally not provided via CLI/API during the subscription period, or is a specific permission / quote level required to populate sub_multiple / margin_multiple?
  2. During the subscription period, is there any other endpoint or field that can provide the estimated public subscription multiple or the margin subscription status?
  3. After listing, the final public offering subscription multiple is published in the allotment results announcement. Is there an endpoint to query that final multiple (historical data) via API?

Use case: IPO subscription decision-making.

Thank you.
