Where each one shines
What FlowAlgo and ORTEX each do best.What FlowAlgo does best
- Monitoring real-time options order flow, unusual activity, Intermarket Sweep Orders, and option block trades from a focused web dashboard.
- Views for reviewing equity block and dark-pool data through the flow tape and Dark Pool Insights module.
- Latency differences: options flow streams near real time, while dark-pool prints and equity block data can be delayed by reporting and exchange rules.
- Alpha AI signals as idea-generation inputs during market hours, while treating the beta labeling and signal limitations as material context.
- Search tools across historical flow data back to mid-2017 to review prior days, tickers, date ranges, and recurring activity patterns.
What ORTEX does best
- Monitoring short interest and securities-lending conditions with utilization, cost to borrow, shares on loan, and percentage of free float on loan.
- Comparison tools for lending-based short-interest estimates with official U.S. exchange-reported short interest and European flagged-short disclosures.
- Tracking intraday and real-time estimates from ORTEX lender and broker data pools where plan access supports those views.
- Research coverage for options activity and flow signals using OPRA-sourced options data, with OPRA terms required before access.
- Alpha-signal modules such as Short Squeeze, EPS, RSI, MACD, and Company Events as research context with back-tested statistics.

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 Pricing, features, and availability may be incomplete or out of date.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.
