I have noticed that the candle H4 of the 17.00 UTC+1 is always negative. I start to believe that a bot starts selling at that time. If it were the BOT that sells for MTGOX for more than 20 days we will see a red candle.
AFAIK - They have completed their sales for the moment. People are monitoring the wallets now and nothing has moved. So this isn't the MT GOX BTC in my opinion.
