Xmes Exchange was the first derivative Exchange I used as a first time derivative trader, but I came to discover xfutures Exchange also, not quite long. Xfutures also allow for the Trading of derivatives and leverage trades. I was actually impressed on these Exchange, concerning the convenient leverage rate it offers. This Exchange have is a partner or have a relationship with okex. Meaning okex share either liquidity or some of the features with xfutures. The liquid of this exchange is actually deep as it pairs with okex. Also the transaction fees can also contribute to the liquid, 0.2%_ 0.5% are charged to the makers and takers respectively. I was actually unhappy when I realized that this exchange is not accessible any longer and has even suspended activities on telegram. This is how I didn't take part here.
