I would like to determine how often a particular stock rebounds after gapping down at open below the LBB(40,2) something like

Open below lower bollinger band(40,2)
Count(high above upper bollinger band(40,2),100) only when the condition in the first line has occured
apply to symlist(xxx)

I suspect I am asking SF to do two things at once.

Any help appreciated

This might do what you're looking for:

set{OBL, Count(open is below lower bollinger band(40,2), 1)}
set{ABL, Count(high is above upper bollinger band(40,2), 1)}
set{prod, OBL * ABL}
apply to symlist(aapl)
draw prod
draw Bollinger Bands(40,2)
chart-time is 1 year

In this case, aapl, hasn't opened below this lower BB during the last year.

This filter would only catch rebounds above the upper BB on the same day as the open below the lower BB. It could be structured differently to plot rebounds that occur after the open below the lower BB.

Thanks Trendscanner.

I see now how to do the count function syntax for both variables, but you're right, the occurences may be too infrequent to be of any use.

Thanks again for responding
