Implementation

How it works:
Users can draw parallel lines to form a price channel (ascending, descending, or horizontal).The user begins by setting the starting point of the first line and extends it until they place the second point. Once the first line is drawn, the user can then drag it to create and position the parallel second line. The width of the channel remains fixed, with the top and bottom lines moving together in parallel.
