JUBLFOOD Double curve in a parallel channel:

A parallel channel is a continuation pattern that slopes up or down and is bound by an upper and lower trend line .
The upper trend line marks resistance and the lower trend line marks support.
Channel Line: The line drawn parallel to the main trend line is called the channel line.

A key concept of technical analysis is that when a resistance or support level is broken, its role is reversed.
If the price falls below a support level , that level will become resistance.
