Um, no I don't think you're doing anything incorrectly.. My example - the pics I've attached in this thread, use a much faster data series with the
indicator using a 10 minute data series of NQ JUN24..
Because you're using a 3min data series for both (I'm guessing this because of the appearance in the pic) you'll get this kind of plot.. It's interesting
to note that the midline is still the (or should be) the qualifying factor for price direction with the green and red still showing OS and OB price action.
Try setting up a chart with say 3sec data or 35V to 50V plotted and add 10min (transparent out the bars).. Then use the 10min data as input to BollingerPro.. You
should get a chart that resembles what I attached here.. Let us know how it goes.. Once you run it this way for awhile you can try other data series
and settings to match the opportunities you're interested in trading..
