The trading time of copper on FXCM platform is the same as that of other trading varieties, but there will be an expiration transaction every other month. Therefore, the trading time of copper is still limited. It is impossible to maintain the open position indefinitely as long as there is enough money, like other metal products such as Fuhui Gold and Silver. I always like to make my own copper, because it is easier to seize the opportunity, and when FXCM Global Gold Exchange makes it, they will also inform me of the delivery date. I think you'd better have time to withdraw money and test it. I think no matter how big the platform is, we should get the money back.
