[torero]

I usually for volume when it nears resistance and support areas to find weakness or strength of the trend. If a stock has been moving up quite a bit and getting near a major resistance fast with high volume. I'd be cautious of this price action despite common sense teaching of high volume price up is good. Chances are it will bounce because increasing volume can be shorts are in or bulls are taking profits furiously at the same time new bulls are buying as well. High volume up price is valid only when it's breaking through the resistance already at least once. If the high volume has been steady then I won't consider this to be the case, only when it noticed in last 2-3 bars that I would consider it a potentially good resistance. Downside is a bit different, high volume going down might pierce it because when the large mass is screaming sell, I'd not step in without clear signs of prices turning up or sideways (stampede can hurt).

That's how I interpret it.
