Shouldn't you divide by 365 instead of 250?
360 daysi divided it by 250 based only on business days. do not know if the rate by day should divide by 365 or something else.

Which day of the week did you short? You got to remember there is the T+2 settlement
As I understand, you pay the short interest fee during that period as wellhow T+2 settlement affects the short fee? if I just hold one overnight, you mean the broker will charge 3 days?
