Hi, I am new to Stockfetcher. I just try to construct a filter myself and have encounter some difficulties---- its regarding Bollinger band. What I want is to have filter out stocks that their Bollinger bands have been narrowing ( Bollinger band converging ) for the last say 10 to 15 days and for the last one or two days the bollinger band expand ( diverging ) a lot with high volume ( say more than 3 times averge trading volume ). I have consturcted some filter steps myself but the filter return zero stocks.... Ha ha . So I suppose I have done some things wrong. Can some one give me a help please. Thanks.

Below is an elementary filter looking for stocks that are in a squeeze; after studying John Carter and Hubert Senters, I came up with this filter. The theory is when the bollingers are inside the keltners the stock is trading in tight consolidation and should break up or down; you'll need to examine futher to determine. You can tweak the last 3 lines of the filter to suit your needs. I tried 300% more volume and got 1 stock; be sure to check if volume is buying or selling. See if you can get Chetron's attention. Hope this helps.

show stock where Upper Bollinger Band(20,2) is below
Upper Keltner Band(20,1.5)
and Lower Bollinger Band(20,2) is above
Lower Keltner Band(20,1.5)
draw Bollinger Band(20,2)
draw Keltner Band(20, 1.5)
show stocks closed between 1 and 250
average volume(90) is > 7500000
volume 1 day ago is 100% > volume 2 days ago

I haven't looked a tmanbones filter yet .... but before I do ...

thomastin ... since you have already attempted at creating a screen ... please post it.

It is much easier to fix some errors then to create a screen from scratch, and hope that we interpret what you were looking for.... Thanks

Thank you guys for all the great ideas. In these two days I have tried some steps using bollinger band, moving average crossing etc etc and surely the result if not exactly what I wanted. Anyway Stockfetcher is new to me and I have already learned a lot. This is my 'work-in-progress' filter and for sure I will make further changes ...the filter only produce a few stocks

Show stocks where close is above 3
and MA(50) and above MA(200) for 20 weeks
and Bollinger Difference(20,1.5) decreasing for the last 10 Days lag 5 days
and low crossed above upper Bollinger Band(20,1.5) in last 2 days
and draw MA(50)
and draw MA(200)
and draw Bollinger Bands(20)
and draw MACD(12,26,9)
and draw ADX(14,14)

thanks mistig, your suggested filter appears to produce a stocklist of what I wanted, though I am not up to level to fully understand the functions / logic of each steps.... for sure I will take effort to learn more. Thanks again.
