//|  1June06 Stache  added traditional view and 2-color Histogram     |
//|  add an alert to it that will 'signal' after a crossover of 'x' bars ... 
//|  at the close of the 1st or ... 2nd ... or 3rd ... or 4th ...
//|  or the 5th ... bar after a crossover ... 
//|  set it for the close of the 'x' (3rd) or whatever I want to test ...
