Several questions you pose Burk. First, I ignore Bollinger Bands, they confuse me and t end to react rather than lead; and I try to keep trading as simple as possible. As for seeking a low on lower volume I find just the reverse to be true. The key, to me, is the prior move. With a big drop down, or up, I look for a heavy volume spike. There's no way to KNOW that a stock or anything you trade is done going down. I just work the probabilities. The market may be in a down trend, but many stocks wil still go up.
