Buy opportunity for Twitter $TWTR ?

Looks like TWTR is going to test support on its 50 day MA, this area; depending on the volume activity, could be a good buy signal. As far a can see the stock is in a very good uptrend, it broke its resistance in the $48 zone, five years in the making. So the longer the base, the greater the breakout. I hope this is the case for TWTR . If you are more cautious the best buy zone is when breaks out its last high in $56.
