The BitMEX trading platform is quite complex (I've tried various exchanges, no less than 20), but it's one of the most functional applications. For experienced traders, this is a big plus, but beginners may find it difficult to navigate due to the multitude of tools and options. By the way, it resembles the ******** platform. Despite its seriousness, there are occasional delays, and orders do not get executed (I encountered this twice in three months).
