Hi,

I was wondering how the rollover cost model works with OANDA since it is stated on their website that it charges/credits interest rates on a second-by-second basis for open trades.

It is easy to obtain the interest rates on their website, but I'm not sure whether I should enter the interest paid/received per 24h and 10000 units (seems the most conservative assumption) or less (The average time in market per day for example).

Thanks!
