Measure short-selling pressure — daily short volume, bi-monthly short interest, off-exchange volume, and the composite short-squeeze score. The first three tools track one stock over time; the last three screen the whole market for the most-shorted and most-squeezable names.
GetShortVolume
FINRA's daily short-sale volume for one stock. Each trading day lists the shares sold short, the short-exempt subset, the total volume in that file, and short volume as a percentage of the total — a fast read on day-to-day shorting pressure, where a reading above ~50% flags heavy bearish flow. This is the daily consolidated short-volume file (reported short activity), not the full exchange tape.
Parameters: ticker (required), startDate, endDate, maxResults.
Ask: "What share of NVIDIA's daily volume has been sold short lately?"
Returns (trimmed):
Daily short volume for NVDA (Nvidia Corp):
| Date | Short Volume | Exempt | Total Volume | Short % |
|------|-------------|--------|-------------|---------|
| 2026-07-08 | 24,611,649 | 84,808 | 64,561,886 | 38.1% |
| 2026-07-09 | 19,515,547 | 120,310 | 55,839,035 | 34.9% |
| 2026-07-10 | 26,602,058 | 178,353 | 66,211,891 | 40.2% |
GetShortInterest
FINRA's bi-monthly short-interest report for one stock. Each settlement date shows the total open short position (shares), the change from the prior report, the average daily trading volume used in the ratio, and days-to-cover (short position ÷ average daily volume). Published twice a month; a days-to-cover above ~5 is the classic squeeze-risk flag.
Parameters: ticker (required), startDate, endDate, maxResults.
Ask: "What is NVIDIA's short interest and days to cover?"
Returns (trimmed):
Short interest for NVDA (Nvidia Corp):
| Settlement Date | Short Position | Change | Avg Daily Volume | Days to Cover |
|----------------|---------------|--------|-----------------|---------------|
| 2026-05-29 | 284,722,716 | -12,243,709 | 180,147,142 | 1.6 |
| 2026-06-15 | 299,666,309 | +14,943,593 | 167,960,279 | 1.8 |
| 2026-06-30 | 310,126,785 | +10,460,476 | 155,989,510 | 2.0 |
GetOffExchangeVolume
Weekly off-exchange trading volume for one stock from FINRA's OTC/ATS Transparency data. Each week breaks out ATS (dark-pool) volume and trade count, non-ATS OTC volume and trade count, and their sum as total off-exchange volume. The FINRA file omits consolidated-tape volume, so it reports the off-exchange totals themselves rather than their share of overall market volume.
Parameters: ticker (required), startDate, endDate, maxResults.
Ask: "How much of NVIDIA's trading is happening in dark pools and off-exchange?"
Returns (trimmed):
Weekly off-exchange (dark pool / OTC) volume for NVDA (Nvidia Corp):
| Week Start | ATS Volume | ATS Trades | Non-ATS OTC Volume | Non-ATS OTC Trades | Total Off-Exchange Volume |
|------------|-----------|-----------|-------------------|-------------------|--------------------------|
| 2026-06-08 | 85,445,818 | 1,321,154 | 276,301,920 | 6,479,991 | 361,747,738 |
| 2026-06-15 | 55,489,159 | 848,691 | 219,576,379 | 4,605,721 | 275,065,538 |
| 2026-06-22 | 80,942,287 | 1,256,234 | 263,394,397 | 6,122,784 | 344,336,684 |
GetShortInterestSnapshot
A market-wide leaderboard at the latest FINRA short-interest settlement date, ranked by days-to-cover (descending) so the most squeeze-prone names surface first. Each row shows the ticker, open short position, change from the prior report, average daily volume, and days-to-cover. Thinly-traded OTC names — whose tiny average daily volume makes the ratio enormous — top the raw board and are pinned at the display cap of 1000.0, so pair this with GetShortSqueezeScores (which takes a liquidity floor) for tradeable candidates.
Parameters: minDaysToCover, maxResults.
Ask: "Which stocks have the highest days-to-cover right now?"
Returns (trimmed):
Short interest snapshot — settlement date 2026-06-30:
| Ticker | Short Position | Change | Avg Daily Volume | Days to Cover |

GetLargestShortVolume
The stocks with the largest short-sale volume on a single trading day (the latest available by default), ranked by short volume descending — ticker, short volume, short-exempt volume, total volume, and short percentage. It shows where daily short selling was most concentrated across the market. Optional date picks a specific day and minShortVolume sets a floor.
Parameters: date, minShortVolume, maxResults.
Ask: "Which stocks had the largest short volume on the latest trading day?"
Returns (trimmed):
Largest short volume — trading day 2026-07-10:
| Ticker | Short Volume | Exempt | Total Volume | Short % |

GetShortSqueezeScores
A market-wide leaderboard of the highest composite short-squeeze scores (0–100), ranked peer-relative across every stock reporting short interest at the latest settlement date. The score is a weighted mean of six factor percentiles — short interest % of shares (30%), days to cover (20%), price vs trailing VWAP (15%), short-volume trend (15%), change in short interest (10%), and fails-to-deliver pressure (10%) — plus catalyst boosts for a price spike, a dollar-volume surge, or imminent earnings (capped at +20). Each row breaks out the underlying factors, active catalysts, market cap, and approximate average daily dollar volume. Pass minMarketCap and/or minDollarVolume to screen out untradeable micro-caps; the sample below is filtered to names above $300M cap and $5M/day.
Parameters: minMarketCap, minDollarVolume, maxResults.
Ask: "Which liquid stocks are the strongest short-squeeze candidates right now?"
Returns (trimmed):
# Highest short-squeeze scores — settlement 2026-06-30
Score = weighted mean of the available factor percentiles (0-100, peer-relative) plus catalyst boosts (price spike / volume surge, capped at +20). Avg $ Volume is approximate (FINRA share volume × market-cap-implied price).
