OANDA Rollover cost model

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!

Per 24h and 10000 units. Oanda does not support anymore the rollover rates with their API, so they have to be manually entered.
