Global Blood Therapeutics has been correcting since hitting a high a week ago.
GoNoGo Trend Pro suggested this with a Counter Trend correction red arrow after the sharp rally that had identified the "Go" trend. Since then, GoNoGo Oscillator has fallen to and found support at the zero line. As it moves back into positive territory we see a green trend continuation icon under the price bar indicating that momentum has returned in the direction of the "Go" trend. Look for price to set a new high.
