How it Works?
It finds and creates channels for each . Channel size is calculated by (Highest - Lowest) * %Channel_size in Loopback Period. After creating channels it calculates that how many in the channels. more in channel means stronger . in the option menu there is S/R Strength, this is the minimum number of that each channel must contain to be S/R. calculation starts from last and go back for "loopback period" which is 300 by default. so last have more priority. Finally after calculating it draws lines.
Number of line is Dynamic and up to 20 lines, that means number of lines changes dynamically. you can see how the script puts Suppport/Resistance lines dynamically by "Replay" button. (if I have time I will try to put a video)
Currently the scripts checks up to 40 in loopback period. it shows up to 20 S/ Rs only for visible area in the chart.
There is option to Show S/R lines as Solid, Dotted or Dashed.
