Only just spotted your message. I post little currently as focussed on my own pip collecting. I learnt lots from Sonic and still use sonic volume indicator. I have written much on volume previously. Have a look at how Islander uses this too. He has provided a nice write up that I commend to you http://www.forexfactory.com/showthre...14628&page=253. Reading this could be the best thing you ever did.
Regards and happy new year.
