What ORTEX does best

  1. Monitor short interest and securities-lending conditions with utilization, cost to borrow, shares on loan, and percentage of free float on loan.

  3. Track intraday and real-time estimates from ORTEX lender and broker data pools where plan access supports those views.
  4. Research options activity and flow signals using OPRA-sourced options data, with OPRA terms required before access.
  5. Use alpha-signal modules such as Short Squeeze, EPS, RSI, MACD, and Company Events as research context with back-tested statistics.

What OTC Markets does best

  1. Research OTCQX, OTCQB, OTCID, Pink, and Expert Market securities through public issuer pages with quotes, charts, financials, company news, and market-tier context.
  2. Use the OTC Markets Stock Screener to narrow OTC securities before moving into issuer pages, filings, quote history, and disclosure context.
  3. License real-time Level 1+ and Level 2+ products when quote, trade, security-reference, or market-participant depth data is needed in production systems.
  4. Use Level 2+ for quote-book depth and market-participant information, with licensing that also includes Level 1 access.
  5. Pull end-of-day OTC pricing files for closing trade and quote data plus OTC-specific attributes such as Caveat Emptor flags and market tier.

Curation & Accuracy

This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).

Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
