Bollinger Band Watchlist

[onemantrading]

I am looking for a bollinger band column for my watch lists.

The column would turn green for any stock that crosses above and stays above the upper bollinger band with a length of 200 and a std deviation of 1.5 based on 1 Day time-frame. If doesn't meet that criteria column would be orange.

If the stock crosses below and stays below the lower bollinger band that has a length of 200 and a std deviation of -1.5 based on 1 Day time-frame the column would be red or dark red. If doesn't meet that criteria column would be orange.

I attempted to use the TOS BollingerBands under columns and it just spit out numbers that didn't seem to coincide with anything on the charts... all the "setups" appeared quite random from one to the next.

Thank You

@onemantrading Here you go... It is up to you to set the timeframe to D when you create the Custom Watchlist Column... I named mine BBX but you can call it whatever you desire...

Edited to add: If you want more results you can replace the crosses above and crosses below with > and <...

def up = close crosses above BollingerBands("length" = 200, "num dev dn" = -1.5, "num dev up" = 1.5)."UpperBand";
def dn = close crosses below BollingerBands("length" = 200, "num dev dn" = -1.5, "num dev up" = 1.5)."LowerBand";

AddLabel(yes, "BBX", Color.BLACK);
AssignBackgroundCOlor(if up then Color.GREEN else if dn then Color.RED else Color.Orange);

Just loaded up and checked it out. Thanks a lot! It works very well. This can weed out many stocks and find opportunities as well.

Glad it's working for you... With some further testing I discovered that a small change filters out some erroneous results... See the updated code below that has "within 1 bar" appended to the BollingerBand() calls...

def up = close crosses above BollingerBands("length" = 200, "num dev dn" = -1.5, "num dev up" = 1.5)."UpperBand" within 1 bar;
def dn = close crosses below BollingerBands("length" = 200, "num dev dn" = -1.5, "num dev up" = 1.5)."LowerBand"within 1 bar;

AddLabel(yes, "BBX", Color.BLACK);
AssignBackgroundCOlor(if up then Color.GREEN else if dn then Color.RED else Color.Orange);
