Totally fake mate. I think that is obviously been manipulate by someone trading there or from the exchange itself. Many exchange using market making feature to their client to produce liquidity and I hate those kind of feature since, it is not natural trading and just faking by the exchange. Yes I actually recommend not to use those kind of exchange. Dont based on CMC they just recording the volume based on the outcome of the exchange but they not monitoring it casually based on the exchange record of the total trades.
