Minimum cluster size (insiders)

min_cluster_size

Optional

Minimum number of DISTINCT insiders that must have bought the same stock inside the rolling window for a cluster to qualify. 3 is the academic-research threshold (Lakonishok-Lee 2001, Cohen-Malloy-Pomorski 2012) — clusters of 3+ insiders outperform single-insider signals by 4-7% annually. 2 catches early-stage signals (CEO+CFO duos). 5+ is the rare mega-cluster (whole board piling in) — historically the strongest reversal signal at distressed names. Anything under 3 is NOT a cluster, just two friends.

Type:integer

Minimum:2

Maximum:20

Default:3

Cluster lookback window

date_range

Optional

How far back to scan for clustered insider buying. last_30d is the canonical academic-research window — insiders rarely act independently on the same thesis if their decisions are spaced more than a month apart. last_60d catches slower-developing clusters (quarterly board cycles). last_90d catches the rare cross-quarter accumulation pattern at deep-value names. Shorter windows = fresher signal but fewer hits. Longer windows = more hits but lower per-cluster strength.

Type:string

Default:last_30d

Options:

last_30dlast_60dlast_90d

Minimum cluster value (USD)

min_value_usd

Optional

Skip clusters where the total combined dollar value of all insider buys is below this threshold. Filters out trivial token buys (1-2K share Director gifts/exercises). Common thresholds: 25000 (OpenInsider default — material-trade screen), 100000 (mid-cap conviction floor), 500000 (large-cap whale-magnet), 1000000 (only mega-clusters). Note: very high thresholds drastically reduce hit count — most quality cluster signals run 50K-300K combined.

Type:integer

Minimum:0

Maximum:100000000

Default:25000

Pure-buy clusters only

exclude_sells

Optional

If true, only return clusters where EVERY insider transaction in the window was a buy (no sells, no exercises, no dispositions mixed in). The is_all_buy=true flag isolates the highest-signal pattern — when no insider is taking money off the table while 3+ are putting it in. Setting to false lets through mixed-direction clusters (e.g., 3 buys + 1 sell — still bullish-leaning but diluted). Pure-buy clusters historically outperform mixed clusters by 2-3% in the 6-month window.

Type:boolean

Default:true

Max cluster records to return

limit

Optional

Maximum number of cluster records to push to the dataset (one row per stock — already aggregated, so a stock with 8 insiders piling in is ONE record not eight). Typical hedge-fund-analyst usage: 10-50 clusters per refresh — that's the full universe of actionable smart-money signals on any given day. Backtesters pull 200+. Each cluster record is a pay-per-result charge of $0.25.

Type:integer

Minimum:1

Maximum:500

Default:25

Restrict to specific tickers (optional)

tickers

Optional

Optional list of stock tickers to restrict the cluster scan to. Useful when you already track a watchlist and only want cluster alerts for those names. Leave empty to scan the full universe of US-listed stocks with recent insider activity. Examples: ['AAPL', 'MSFT', 'NVDA'] or ['MYGN', 'BABA', 'INTC']. Case-insensitive, max 100 tickers.

Type:array

Default:

[]

Include industry/sector classification

include_industry

Optional

If true, include the OpenInsider-supplied industry classification (e.g., 'Pharmaceutical Preparations', 'Semiconductors', 'Commercial Banks') as the sector field on each cluster record. Used by quant funds to group cluster signals by sector — a cluster wave across multiple regional banks is a different signal than one isolated bank cluster. Set to false to skip and save a tiny amount of bandwidth.

Type:boolean

Default:true
