It is unlikely that MARK-E offers Islamic accounts, as these accounts are generally associated with forex or stock brokers that comply with Sharia law. Islamic accounts are structured to avoid interest-based transactions, which are a key concern in the traditional financial markets. Given that MARK-E specializes in energy trading, it’s not common for firms in this niche to offer Islamic accounts. If this is an essential feature for you, I suggest contacting MARK-E directly for clarification on this matter.
