Scan for inside bars

Hi Pete.  I am looking for a code that simply scans for stocks in which the previous bar was and inside bar.  I came across the code below you provided in a previous post but it doesn’t seem to identify stocks when I run an intra day scan.

def count = 2;
def range = high – low;
#def priorrange = high[1] – low[1];
def priorrange = range[1];
def nibsize = absvalue(((open – close) / (open[1] – close[1])-1));
def sizeConstraint = absvalue((range / priorrange)-1) >= .5 and nibsize >= .5;
def hiLowContraint = high <=high[1] and low >= low[1];
def inside_bar = sizeConstraint and hiLowContraint;
#plot s = inside_bar && lowest(range,count);
plot scan = inside_bar[0];
AssignPriceColor(if inside_bar then Color.WHITE else Color.CURRENT);
