Is trading currencies, gold, silver, and oil on the "Tradelink" exchange permissible or impermissible (halal or haram)?

It is not permissible to trade through the aforementioned website due to its inclusion of the margin trading system, which is impermissible in Sharia, and the presence of trading on stock indices, which is a type of trading that is not permissible because it is pure gambling, being the sale of an imaginary thing that cannot exist. A resolution to this effect was issued by the Islamic Fiqh Academy.
