Stair-step pattern developing in ARWR

The last four days have been nice and tight, holding the gains made on the breakout 03/05. The decreasing volume coinciding with fact that the overall daily ranges of the last 4 days have been decreasing add another layer of bullishness. I have noticed the high of the last four days has been decreasing and I think this can be used to determine if the stock is going to breakout Monday. If it immediately goes above the high of the last two days, 7.45 and 7.51, I think its fair to assume the pattern has changed.
