Yep possibly.

Just make sure all that volume was traded "on market"
as, if it was an off market transfer (or crossed trade of some sort), then it usually won't make any difference to the chart, and trading will continue as if that volume was not there on the chart.

cheers

PS- I should have some more time next week, so I will be able to spend some more time over here.
