AUDUSD Swap

 
I'm new, apologies for the question... but I don't understand the Swap charge for my current short position (1.25 lots) opened on Friday 5/24. Swap fee was $18.50, then another $18.50 swap added after 4EST today for a total of $37.00 in swap since trade initiated on Friday. This doesn't seem to line up with the swap rates for short position, just wondering what I am missing. Thanks!
 
  1. Swap is computed 5pm ET. No swap if no open orders at that time. Swap on Wednesday is three (3) times larger than other days. Contract clears three days later, so include the weekend.
  2. "Doesn't seem" is meaningless to us. There are no mind readers here and our crystal balls are cracked.
