Hi brother,
Forex trading is Halal provided you do not receive or pay any overnight interest from your broker.
Islamic Accounts are designed not to receive or pay interest on overnight trades but you must check that your Islamic forex trading account is properly configured not to receive or pay overnight swaps.
While opening your Islamic forex trading account, make it expressly clear to your broker that you are of Muslim faith and do not want a partial swap-free account but instead want a fully swap-free account.
This is important because certain swap-free accounts are not designed for Muslims and they can suddenly start charging you overnight swap interest when they notice you are leaving too many trades open overnight.
