In charting, the term “descending trend channel” refers to a set of parallel trend lines which indicate the highest and lowest points in a consistently declining rate.
When used on a stock chart, both of the lines making up a descending trend channel are straight, with the lower line following the lowest prices and the upper line following the highest prices indicated by the descending line. A descending trend line is used to show that a rate has declined steadily over a given period.
