I would welcome any suggestions to improve on this filter. I am trying to pick stocks trending up that are ready to move and following the upper bb right after it has narrowed. I am fairly new and just learning to write these so I am sure it could be improved on

Fetcher[bollinger(20) width near 8 month low 2 days ago
and lower bollinger band(20) has been decreasing over the last 1 days
and upper bollinger band(20) has been increasing over the last 1 days
and close is near upper bollinger(20)
and close is between 2 and 20
and average volume(90) is greater than 80,000
and 60 day slope of the close is above 0
volume is greater than volume 1 day ago

I noticed no one had replied to this thread so I thought I would give it a shot.

I am not exactly sure how to improve your filter in terms of better hits but you might consider writing it like this.

bollinger(20) width near 8 month low
AND bollinger band(20) width increasing
AND close is near upper bollinger(20)
AND close is between 2 and 20
AND average volume(90) is above 80000
AND LRS(60) is above 0
AND volume is increasing

This should yeild results that are very near the results that your original filter had with the addition of a few extra symbols that will get through the initial squeeze criterea.

You may also be able to leverage "%B" in place of "close is near upper bollinger(20)" although you probably won't get much better than what you already have for that line.

Another thing I notice is that you have implied volume types of indicator with "volume is increasing". You may find better results by using MFI or some other volume based filter.

I personally think you have done a good job of not poluting the filter by adding addional price action indicators and would advise you to keep it that way.

I am certainly not the authority here on technical analysis here. I do hope you find some of this useful.

This is what I use to build a watch list:

Fetcher[ /* Parameters */
Bollinger Width(20,2) reached a new 6 month low within the last 5 days
weekly slow stochastics(4) fast % K is above weekly slow stochastics(4) slow %d
weekly slow Stochastics(4) fast % K is below 75
close crossed above Upper Bollinger Band(20,2)

/* Variables */
set {b100, Bollinger Width(20,2)*100}

/* Charting */

/* Columns */
add column b100 {BBandW}

/* Price Volume Limits */
price is greater than 1.00
volume is greater than 100000

. . . I also use a volume indicator like Intraday Intensity or MFI along with a standard MACD(12,26,9) on the chart to find good candidates. You can also remove the "close over upper BB" to fill a watchlist that could play stocks either way.
