I've been trying to write a scan for tightening bollinger bands with a breakout, and am having mixed success. What I am aiming for is a combination of tight bands ( http://stockcharts.com/h-sc/ui?s=ACE/A.TO&p=D&yr=0&mn=10&dy=0&id=p78670659849 ) with a typical breakout above upper band ( http://stockcharts.com/h-sc/ui?s=PIF/UN.TO&p=D&yr=0&mn=10&dy=0&id=p78670659849 ).

This is what I have come up with but it seems hit or miss:

• For the last market close:
[type = stock] and [country = canada] and [daily sma(20,daily volume) > 40000] and [daily sma(60,daily close) > 1] and[daily upper bb(20,2.0,daily close)<= daily close*1.06] and [daily lower bb(20,2.0,daily close>=daily close*0.94] and [close>0.001] and[close<30] and[yesterday's close<=yesterday's upper bb] and [close> upper bb]

Is there a way to refine the scan so that it finds charts like

I would greatly appreciate any help. Thanks
