Just using fibonacci retracements, $489.82 up next... $482.67 support... if $489.82 goes, you can't argue the bullishness of GOOG, and a gap fill is in order as the next resistance... and that's around $505...
Strong gap-open next week, and it might be time to sell the house short though with the way the weekly charts are set up... depends a lot on today's close though...
