Frequently Asked Questions

How is ORTEX short interest data different from exchange data?

US exchanges only publish short interest twice monthly with an 8-day delay. ORTEX sources data daily from 700k+ pools of agent lenders, prime brokers, and broker-dealers — giving you a more timely view of short selling activity.

Does ORTEX offer enterprise API access?

Yes. Enterprise APIs support full-day downloads, index rebalance forecasts, high-volume ingestion, and custom delivery pipelines. Contact sales@ortex.com for pricing.
