Short Interest

API TraderAPI QuantAPI Developer

API to retrieve short interest for a given ticker on a given exchange

This API provides the raw number of shares estimated to be shorted, the widely used short-interest percentage of free float, the number of shares available to trade, and the USD value of the estimated short position.

Available Data Points:

  • Date: Date for the short interest data. (YYYY-MM-DD format).
  • Short Interest Percentage of Free Float: Short interest estimate as % of free float.
  • Short Interest Shares: Short interest estimate in number of shares.
  • Short Interest USD: USD value (siShares * closing price).

Try it out! You can test the API with the trial key TEST. Simply include it in your request headers; either here, or add the header "Ortex-Api-Key": "TEST" to your http request.

Trial key restrictions: Trial keys may be limited to a specific date range and set of regions. Requests outside the allowed regions or entirely outside the allowed date range are rejected; a date window that partially overlaps the allowed range is trimmed to it, reported in meta.restriction.

Path Params
string
required

Where to find the instrument: a venue (exchange symbol, MIC or ISO-2 country) or an identifier scheme (tid, sid, cid, isin, figi). See Identifying an instrument.

string
required

The ticker on that venue, or the value in that scheme. An ISIN, sid, cid or share-class FIGI answers for the main listing only; reference/listings lists the others. See Identifying an instrument.

Query Params
date
required

Inclusive start of the returned date window. Format: YYYY-MM-DD.

Also selects the instrument: the ticker resolves to the listing that held it on the exchange in the URL path on this date. To retrieve a delisted or renamed company, use its former exchange and ticker with a from_date from when it was listed. An identifier path (/stock/isin|figi|sid|cid/<value>/…) resolves at this date too. The instrument block in the response names the company the data belongs to.

date

Inclusive end of the returned date window (defaults to today). Format: YYYY-MM-DD.

boolean
Defaults to true

Whether share counts — and, on the closing-prices endpoints, prices and volumes — are adjusted to today's terms (default) or returned as-was on the data date. Pass false for unadjusted (as-was) values.

integer

Page number within the paginated result set. Must be >= 1. Defaults to 1.

integer

Number of rows per page. The default and the maximum allowed depend on the API tier; a value above the tier maximum is rejected with 400 invalidPageSize.
