Pyramiding confirmation

Hey Pat
just to make sure I understand
you add 30% of your position after the stock goes up 2%-2.5% from the initial buy price

and then add another 20% if it goes up another 2%-2.5%.
 
do both add-ons have to be confirmed with volume a volume surge? 
and if so what would you do or add if you only see the volume surge closer to where the 2nd add on should be?

thanks
