Thank you, cmacdon, for so generously sharing your BollingerBand Squeeze indicator with us in the Bullscript sub forum. For other members, if the indicator does not atfirst appear as in cmacdon’s demonstration chart, do as he suggests...rightclick properties and turn on the features you want in the Style tab. I was likea kid in a lolly shop and just ploughed straight in without reading his fullinstructions J

When I get my head fully around all the features I will tryto convert this into a scan for your “Bingo” BBsqueezes, and report back herewith it for your scrutiny.

I am still curious to learn how I could scan for my originalidea, since I have been in this situation before with other scans..i.e. how extremeis today’s whatever indicator eg.  A candlestickpattern such as Big White Tower..how big is todays BWT compared with previousexamples for that share.  

Anyway, back to Boll Bands. How could I use a function suchas barssince, to scan say the entire ASX 200 to produce a list that tells mehow today’s bandwidth compares with previous ones... I realise your ATR filteris doing something similar. I suppose I’m just trying to figure out how afetrure such as barssince works.

If today’s Bollinger Bandwidth is not particularly narrow itwould return a value of 0 or 1..i.e. it’s the narrowest it’s been in only oneday..maybe not even contracting at all but expanding. But if it’s the narrowestin say 201 days then place that result in a column. Then I sort that column andfocus my attention on the top 10 narrowest, using your Bingo indicator asconfirmation.

Thank you most kindly again for your help.

Not sure if you had a more recent reply than mine.

I coded this very crude scan for looking back on the lowest BB squeeze in 51 days.

The codes that it throws up, you can then sort by lowest squeeze etc.

{Variables}
bbw := formula("Bollinger Bandwidth", Close, Simple, 20, 2);
BBup := formula("Bollinger Bands", Close, Simple, 20, 2);
BBdn := formula("Bollinger Bands[3]", Close, Simple, 20, 2);
BBmid := formula("Bollinger Bands[2]", Close, Simple, 20, 2);

{Condition}

filter := 
bbw<hist(llv(bbw,50),1)   {today is less than lowest bandwidth in 50 days}
and (BBup<=hist(BBup,1)) {Bands squeezing}
and (BBdn>=hist(BBdn,1));
filter;

{Columns}
[name="Bandwidth"; dp="3"] bbw;

Additional help please...

But this particular squeeze could be the lowest bandwidth in not 51 but 100 days or more!

What I would like to do but don't know how ..maybe someone can help is to additionally use a function such as barssince??? to tell me exactly how many days ago was there a BollBand squeeze that was even less than today's...and then list that number in the {Columns} results.

Maybe that would require a completely separate scan??

Thank you for your help.

thegrid, muck around and have fun.
I have one that picks up some but you can experiment with heaps of
different ideas.
Mine is "low is between high and low every bar for the last 4 bars"
You can make it 6 or whatever. You will find a lot of stock going along
sideways but there should be a few flags in there

Jalna is right umm the Bollinger Bandwidth indicator shows the distance between the bands.   eg. a scan of <0.065 would have picked up the squeezes (before the major moves) on BHP this year.   

Good Trading

Hi thegrid, You can write a scan that says
Bollinger Bandwidth is the lowest it has been over so X many days
Other than that i'm not sure what else]]> Sun, 17 Feb 2008 18:06:33 +0000 http://www.bullcharts.com.au/forum/forum_posts.asp?TID=457&PID=1703#1703 Bollinger Band Squeeze : Does Bullcharts have a scan to... http://www.bullcharts.com.au/forum/forum_posts.asp?TID=457&PID=1697#1697 Author: thegrid

Does Bullcharts have a scan to identify Bollinger Band Squeeze candidates.
