Roy,

Thanks! I was hoping you'd get in on this.

Mike & Chellester, Roy is the KING when it comes to working with 
formulas. He has spent countless hours working with these formulas. 
His work on the Trade Equity indicators is pure genius. We are 
honored to have a copy of it in the group files section. I would 
encourage you and everyone else to take some time and study this 
work. It is an education that would take you lierally years to obtain 
on your own. The greatest part is that Roy offers this work for FREE!

Roy, you are one in a million!! THANKS,

Preston
