Went to sleep, woke up - 33% profit adjustment. Exactly as I predicted.
Good bye Bitmex. Call me back when you have max 1:5 leverage.
Thank you for your replies in this post, now I clearly see that 1:100 leverage by Bitmex is simple kind of marketing trick to attract more traders. After I read your replies and their ADL policy, I've come to the clear conclusion that Bitmex is a trash exchange.
