Newbie asking a newbie interest rate question:

::1st post
::3rd week into the trading world
::Using CMS-Forex with VTrader

How do you calculate the daily interest using the information provided by Vtrader? The results from my calculation do not match the real-live-demo results.

My example being long on USD/CHF with an IntBuy of 5.0.

honestly, I don't know what you are asking because I'm newbie.
