Looking for an exploration that finds securities evolving within a corridor

[""André F. Gallant"" <agallant@xxxxxxxx>]

Hi,

I am looking for an exploration that finds securities evolving within a 
corridor. In other words, it will find securities where their curent trend 
shows they are zigzaging up and down within a corridor.

Any idea what can be used to filter these securities.

Thanks for your help

André
