$GRPN In EWT, todays low at 18.75 would make a nice wave 2 down. Too early to tell for now, but as labeled in this current map, it's a perfect 50% retrace of wave [1] and a nice wave c = 2.62% of wave a for an expanded flat for [2], which is a common fib extension. Should get an indication if this map is valid if this price area holds, and some solid buying next week starts to indicate possible wave [3] startup
