Trendline Pairs (Deep Search)

After getting good response on Wedge-and-Flag-Finder-Multi-zigzag, I thought I will build little bit further into the script.

Main differences

• Uses deep search algorithm for patterns instead of just using last 5 pivots
  
• Flag pattern is removed so that we can concentrate mainly on trend line pairs
  
• More number of overall patterns.
  

Trend Patterns Included

• Channel - Rising, Falling, Ranging
  
• Wedge - Rising, Falling + Expanding, Contracting types
  
• Triangle - Expanding, Contracting
  
• Indeterminate - Happens in rare cases where angle calculation results in error. It may still belong to one of the above patterns.
  

Please note:

• This is published as free to use but protected source code indicator. This is because the script contains deep search algorithm which isn't made public yet and is also been used in other invite only scripts.
  
• Will not be adding alerts to this indicator.
