Hi Trader,
This was a topic we had a discussion the other day.
Check this link out:

also
http://tradingqna.com/32528/what-to-look-out-for-on-the-attached-charts
From the above data, We came to a conclusion that in some cases the volume of buyers and sellers has no direct co-relation to the direction of price.
Hope this helps,
HAPPY TRADING.
