I don't believe you will see much movement leading up to the fork, at least not on heavy volume.  Those who can really move DRK aren't going to be the kind to buy it up just prior to a hard fork that has been known about for awhile.  They are the kind who are going to have adjusted their positions days or weeks prior based upon their risk-analysis.  

Get your popcorn ready for after the fork as that is when the fun will really begin.  Until then, give your eyes a rest.
