Updated July 2026 · Head-to-head comparison by AltIndex
A side-by-side look at Ortex and AltIndex — what each platform tracks, who it’s built for, and where the differences show up in real use.
Ortex is the leading retail-accessible source of short-interest data, providing real-time short-interest estimates, cost-to-borrow rates, days-to-cover ratios and short-squeeze risk scores. The platform launched after the early-2021 retail-investor short-squeeze cycle exposed how poor public short-interest data was — most public sources publish bi-monthly with multi-week lags, while Ortex offers daily updates sourced from securities lending data.
The product is used most heavily by traders interested in short-squeeze candidates, short-side investors who want to verify their thesis, and retail investors tracking high-short-interest names. Coverage extends to US, UK, European and Canadian exchanges. Paid tiers unlock real-time data, alerts, sector heatmaps and historical archives.
What Ortex doesn't have: comprehensive alternative-data signal coverage, no AI scoring layer, no social-platform tracking, no hiring data. It's a focused short-interest data terminal, not a multi-signal research platform.
Pricing: Ortex Premium is $69/mo, Pro is $124/mo, with higher tiers for institutional needs. The high-end pricing reflects the proprietary short-interest data source.

Alternative-data signals
Refresh on every signal
Ortex and AltIndex have a narrow but real overlap in alternative-data positioning. Ortex specializes deeply in one signal — short interest and the related securities-lending data. AltIndex covers a broader signal set including web traffic, 8 social-platform audiences, hiring activity, news mentions, sentiment and insider trades, plus our AI Score.
A trader specifically tracking short-squeeze candidates or running short-side positions gets best-in-class data from Ortex. An investor who wants comprehensive alt-data coverage across signals — and a single AI Score that consolidates them — gets that from AltIndex.
Many active investors use both: Ortex for short-interest depth, AltIndex for everything else. If your strategy is short-squeeze-driven, Ortex is essential. If your strategy is alternative-data-driven across multiple signal categories, AltIndex is the broader platform.
What AltIndex has that Ortex doesn't: signal coverage beyond short interest (web traffic, social, hiring, news, sentiment), the AI Score combining them, and a lower price point for the broader signal set. Where Ortex wins: the depth and freshness of short-interest data specifically, which AltIndex doesn't try to match.
