Hi @pip2hunt
To which commodities are you refering in particular?
FOREX.com offers competitive rollover rates for currency pairs, but our commodity CFDs (contracts for difference) expire every month, so there is no rollover interest earned or paid.
Instead, the interest rate you earn or pay is factored into the daily price fluctuations similar to how it works with the corresponding commodity futures contract. That might be why you couldn’t find a website to compare commodity rolls the way you did for currency rolls.
