Can someone explain this to me? I noticed the volume and margin were increasing on their own ( without me adding any margin to the trade) . I opened this trade as an experiment with an initial volume of 13 usdt , it got increased to 15 and now has reached 17usdt. Also I have to pay the funding fee according to the new increased volume. Although the volume is low right now but it happened with me a few days ago my volume increased from 150usdt to 200 on it's on. $RIVER
