Where does SQUEEZR get its short interest data?

SQUEEZR uses official FINRA short interest data, updated bi-weekly on the 1st and 15th of each month. Borrow data (utilization, cost-to-borrow, shares available) comes from iborrowdesk.com which mirrors Interactive Brokers inventory. Fails-to-deliver data comes directly from SEC EDGAR. Real-time price quotes use the Finnhub API.

Is SQUEEZR free to use?

Yes, SQUEEZR is completely free. All data — FINRA short interest, SEC fails-to-deliver, borrow rates, dark pool data, and AI analysis — is available at no cost at investorturf.com/squeezr/

What is dark pool data and why does it matter for short squeezes?

Dark pools are private off-exchange trading venues where large institutional trades are executed away from public markets. High dark pool volume in a heavily shorted stock can indicate accumulation by large players, which may precede a short squeeze. SQUEEZR tracks dark pool off-exchange volume percentage using official FINRA OTC Transparency data.

PFOF · ORDER ROUTING · RESTRICTION HISTORY

⛔ AVOID — RESTRICTED STOCKS IN 2021

These brokers halted or restricted buying of GME, AMC and other heavily shorted stocks during the Jan 2021 squeeze — protecting short sellers at the expense of retail investors.

ROBINHOOD AVOID AT ALL COSTS

Restricted buying on 13 stocks Jan 28 2021. Heavy PFOF revenue model. Sells your order flow to Citadel — the same firm shorting the stocks you're buying.

⚠ PAYMENT FOR ORDER FLOW

These brokers sell your orders to market makers (Citadel, Virtu, etc.) before they reach the open market. You may get slightly worse prices. Legal in the US — banned in UK/EU.

✓ GOOD — DIRECT ROUTING

These brokers route orders directly to exchanges or use price improvement. Did not restrict buying during the 2021 squeeze. Better execution for active traders.

Free Short Squeeze Tracker — Live FINRA, SEC & Dark Pool Data

SQUEEZR is a free real-time short squeeze screener that pulls official data directly from FINRA and the SEC. Track short interest, fails-to-deliver, borrow rates, utilization, dark pool off-exchange volume, and AI-powered squeeze signals for heavily shorted stocks including AMC, GME, TSLA, RIVN, SOFI, PLTR, MSTR and more.

What is a Short Squeeze?

A short squeeze occurs when a heavily shorted stock rises sharply in price, forcing short sellers to buy back shares to cover their positions. Key indicators include high short interest as a percentage of float, high days-to-cover ratio, high borrow utilization, elevated cost-to-borrow (CTB) rates, and significant fails-to-deliver (FTD) volume.

What Data Does SQUEEZR Track?

Short Interest (FINRA) — Official FINRA short interest data updated bi-weekly, including shares short and % of float. Fails to Deliver (SEC EDGAR) — SEC-reported FTD data, a key indicator of settlement failures and potential forced buying pressure. Borrow Data (iborrowdesk) — Live utilization rate, cost to borrow (CTB % annualised), and shares available to short from Interactive Brokers. Dark Pool Data (FINRA OTC) — Off-exchange volume percentage, weekly trend, and venue breakdown. AI Analysis — Claude-powered squeeze assessment in plain English with risk-adjusted commentary.

Squeeze Score & Signals

SQUEEZR calculates a proprietary squeeze score from 0-100 across seven weighted factors: short interest % of float (32pts), days to cover (22pts), borrow utilization (18pts), cost to borrow (12pts), share availability (8pts), fails-to-deliver (8pts), and short interest momentum (+5pts). The Signals tab interprets this data into plain-English alerts — flagging critical conditions like borrow pool exhaustion, FTD spikes, dark pool surges, and multi-factor convergence.
