Square of time

[Marco Guglielmo <mgugliel@xxxxxxxxxxxxxxxx>]

Hi to the list;

I am trying to understand how correctly use the Gann's square of time and 
Gann's grid.
Is there somebody in the list that can summarize me how to correcly 
proceed to use these techniques and /or in which book are explained the 
rule of these methods?

I thanks a lot for any advice
