4H OBV - manipulation??

Check out the 4 HR OBV I drew weeks ago. I drew a descending trend line, then the 4H OBV turned positive and passed the negative trend line.

Now the recent volume has been so bearish that incredibly, the 4H OBV has rejoined the significantly far away negative trend line - and has rejoined it perfectly.

MT GOX GUY!! STOP IT!!!
