Tim,
There are many ways to write a filter. If you don't mind using long filters, and if you want to construct a filter to pick out stocks with the narrowest daily range in past 7 days, and if you also want a requirement on a minimum of 100,000 volume, I'd write...
/*Establish a reference range*/
set{Highest,high+0.001}
set{Lowest,low minus 0.001}
/*Count the highs and lows that comply with this reference range*/
/*Yesterday's bar*/
set{HighCount1,count(high 1 day ago is below Highest,1)}
set{LowCount1,count(low 1 day ago is above Lowest,1)}
/*The bar 2 days ago*/
set{HighCount2,count(high 2 days ago is below Highest,1)}
set{LowCount2,count(low 2 days ago is above Lowest,1)}
...
...
/*The bar 6 days ago*/
set{HighCount6,count(high 6 days ago is below Highest,1)}
set{LowCount6,count(low 6 days ago is above Lowest,1)}
/*Add up these 6 * 2 = 12 counts*/
set{count1,HighCount1+LowCount1}
set{count2,HighCount2+count1}
set{count3,LowCount2+count2}
set{count4,HighCount3+count3}
...
...
set{count11,LowCount6+count10}
/*Set a minimum limit for the number of highs and lows that have to comply with this reference range*/
and count11 is above 10 /*This count of 10 can be any number between 0 and 11.999*/
/*Add a global filter*/
and close is between 1 and 250
and volume 30 day low is above 100000
And once your new filter is working, you will be able to tweak it; you can, for example, gradually narrow the reference range, and observe how many stocks your new filter yields.
I hope this helps.
Regards,
Rob

Hi Rob,
Thank you very much for taking the time and trouble to help me. I truly appreciate it. I will take your filter and play with it to see how it works. It was a thought that a narrow range day might give you an entry into a reasonably low risk trade. Once again, thank you.
Kindest regards,
Tim
