Big movement expected on 3m Co. after a breach of 176.47

3m Co. has broken through a line of 176.47 and suggests a possible movement to 177.67 within the next 8 hours. It has tested this line numerous times in the past, so one should probably wait for a confirmation of this breakout before placing a trade. If the breakout doesn’t confirm, we could see a retracement back to lines seen in the last 6 days.
