Channels

"In trending markets, ride the channel. In ranging markets, fade the edges." Unknown

Channels define dynamic support and resistance. Upper band shows where price tends to find resistance; lower band shows support. Width measures volatility; price position within channel measures momentum and mean-reversion potential.
