Borrow Fee (CTB)
Track Interactive Brokers borrow fee, available shares, rebate, recent changes, and daily rate ranges.
Read the latest values
The latest summary shows Interactive Brokers available shares, annualized borrow fee, and rebate at the displayed time.
Recent Changes lists each change in fee, available shares, or rebate.
Track the daily fee range
The chart aggregates borrow fee observations into daily open, high, low, and close values. Candle, OHLC, and Line views use the same daily data.
The lower series shows the highest number of shares available during each day.
Create a Borrow Fee alert
Create Alert starts with the current symbol. Add up to three conditions for fee, shares available, or rebate. Conditions can watch crossings, availability changes, or absolute and relative changes over a window from 15 minutes through 30 days.
The current observation seeds a new or edited alert. An event is sent after the complete condition changes from false to true, rather than repeating while it remains true.
Use the snapshot history
The Data table records each Interactive Brokers observation with its time, fee, available shares, and rebate.
This is data from one broker. It does not represent total securities-lending inventory or a market-wide borrow rate.
Borrow Fee is also available as a chart indicator. It supports Candle, OHLC, and Line styles, optional availability volume, custom colors, and a different source symbol.
