In depth comparison

IBorrowDesk

iborrowdesk.com

Tracks stock-loan availability and borrow fee data as reported by Interactive Brokers (IBKR). Updates roughly every 15 minutes during North American trading hours and hourly elsewhere on weekdays. The data reflects IBKR only and not the wider market. The site is unaffiliated with IBKR; displayed quotes are provided by IEX. A paid Patron tier adds longer history, CSV exports, and more tracking capacity.
