Risk warning. Wickwise is free education only — nothing here is financial advice or a recommendation to buy or sell. Trading and investing involve risk: you can lose some or all of the money you invest. Leveraged products such as CFDs, futures and options carry a particularly high risk of fast losses; depending on the product, losses can even exceed the money you paid in.
