Horizontal Channel

What Does Horizontal Channel Mean?
Using trendlines to connect variable pivot highs and lows shows price contained between the upper line of resistance and lower line of support. This is price range or sideways trend. This horizontal channel or sideways trend is also a rectangle pattern (dotted lines show the pattern). Buying and selling pressure is equal and the prevailing direction of price sideways. This happens in periods of price consolidation.

Investopedia explains Horizontal Channel
Price is framed out in a trading range by the pivot highs (resistance) and pivot lows (support). Trendlines drawn on pivots give a visual picture of price action. A new high in price above the horizontal channel is a technical buy signal. A new low in price below the horizontal channel (or rectangle pattern) is a technical sell signal.
