Our take
The bottom line
ORTEX and Reflexivity cover a lot of the same ground (7 shared categories, including quant, news, and calendar), so for the basics you won't go far wrong with either. ORTEX simply does more: 16 categories to Reflexivity's 13, including short interest, insider data, and data visualizations, plus a mobile app. Reflexivity counters by keeping things simpler.

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 Pricing, features, and availability may be incomplete or out of date.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