How are overnight borrow rates calculated?

When holding any short position overnight, an overnight borrow fee will
apply. This fee will be charged every day you hold a short position
overnight and until the short position is covered.

You can see an estimate of the fee by logging into your client portal and
going to: Tools > Overnight Borrow Calculator.

The overnight borrow calculator will include all weekdays, weekends, and
holidays where a fee will apply.

It is important to check the overnight borrow calculator every day you
plan on holding your short position overnight.
