Yes, I didn't like how they have reversed those trades. I think that wasn't fair toward people that were involved in those trades and that actually got good deals out of it.
But where did you get from that they are faking their volumes? Their volumes are already small enough. If you have some other informations, please share it with us. Or you are just talking from the top of your head?
i dont like the trade reversal too, but AFAIK they are obligated to do so. and we can be sure they dont fake their volume and that the owners dont trade their temselves...
^ all of that comes with regulation ;-)
