Optuma Scripting

Hi I am trying to use this script to find out the price close outside the lower bollinger band. But could not see any script for outside LowerBB. or a breakout price outside lower bollinger

CLOSE(Day(PERIODAMOUNT=1)) > BBOB(Day(Day(PERIODAMOUNT=1), PERIODAMOUNT=1), DEFAULT=LowerLine, BARS=21, STYLE=simple, CALC=Low)

Hi,

The following script will show a result when the Close of a bar is outside of the lower line of a Bollinger Bands (20 Day, 2 Std Deviation settings).

V1 = BB(STDDEV=2.0, BARS=20).LowerLine ;
Close() < V1

The green shaded zone on the chart shows the candles matching this criteria…
