Short-Restriction Flags

Per-ticker daily short-sale restriction state: whether a short-sale control is active, margin-short and SBL limit values, disposition-active flag, and a restriction note. Derived from short-sale-balance-control + attention/disposition events. Not a forecast, not a recommendation.

Overview

This dataset is in build and not yet queryable via the API. The coverage and honest limitations below are the real database state; it moves off "Building" once serving lands (targeted 8/1).

FieldTypeDescription

ms_limit_value

disposition_activebool
restriction_notetextscope per row

Coverage

42,609 rows, 2009-12-29..2026-07-31, 1,646 tickers. HONEST GAP: the official (below-par short-sale eligibility) list is not loaded — has_short_sale_control reflects the control/disposition sources present; restriction_note explains scope per row.

Example response

A real response from this endpoint. Rows are returned under "data", and provenance is carried in the shape shown below — it is not identical across datasets, so read this page's rather than assuming another's.

{  "dataset_id": "short-restriction-flags",  "row_count": 3,  "data": [    {      "ticker": "8383",      "market": "TPEx",      "trade_date": "2026-07-31",      "has_short_sale_control": false,      "ms_limit_value": null,      "sbl_limit_value": null,      "disposition_active": true,      "restriction_note": null    },    {      "ticker": "6907",      "market": "TPEx",      "trade_date": "2026-07-30",      "has_short_sale_control": false,      "ms_limit_value": null,      "sbl_limit_value": null,      "disposition_active": true,      "restriction_note": null    },    {      "ticker": "6173",      "market": "TPEx",      "trade_date": "2026-07-30",      "has_short_sale_control": false,      "ms_limit_value": null,      "sbl_limit_value": null,      "disposition_active": true,      "restriction_note": null    }  ]}

Captured from the live API on 2026-07-20.

Getting started

  1. Put your key in the X-API-Key header.
  2. Add query parameters (symbol, date range, limit).
  3. Send the request and read the data array.
curl "https://api.twmarketdata.com/v2/datasets/short-restriction-flags?symbol=2330" \  -H "X-API-Key: sk_live_..."

Filtering

ParameterRequiredTypeDescription
symbolYesstringTicker, e.g. 2330.
start_dateNostring (YYYY-MM-DD)Start of the query range.
end_dateNostring (YYYY-MM-DD)End of the query range.
limitNointegerMaximum rows to return.

Python

A first call:

import requests resp = requests.get(    "https://api.twmarketdata.com/v2/datasets/short-restriction-flags",    params={"symbol": "2330"},    headers={"X-API-Key": "sk_live_..."},)resp.raise_for_status()print(resp.json()["data"])

With a date-range filter:

import requests # The full verified example — the same call with every supported filter set.resp = requests.get(    "https://api.twmarketdata.com/v2/datasets/short-restriction-flags",    params={"symbol": "2330"},    headers={"X-API-Key": "sk_live_..."},)resp.raise_for_status()for row in resp.json()["data"]:    print(row)

OpenAPI

This endpoint is GET /v2/datasets/short-restriction-flags. The full machine-readable schema (parameters, security, response envelope) lives in the OpenAPI spec.

Notes & limitations

  • In build (not yet generally available): not yet served over the API. The figures above are the measured database state (WAVE_L_REGISTRY), shown honestly before serving lands — not a live endpoint yet.

Request & Response

Request

curl "https://api.twmarketdata.com/v2/datasets/short-restriction-flags?symbol=2330&start_date=2026-01-01&end_date=2026-06-30&limit=5" \  -H "X-API-Key: $TWMD_API_KEY"

Authenticate with the X-API-Key header, using a sk_live_ key issued in the dashboard.

Captured from a real call to this endpoint — not written by hand.

This dataset returns its rows under "data". The envelope differs between datasets, so read this one rather than reusing another page's shape.

The grade badge on this page is a documentation classification, not a response field.
