ZigZag (Using Line Array)

This is standard zigzag indicator. I just coded them using lines array feature of pine - so that it can be done in least number of lines of code.

Few possible improvements:

• Use label array to mark HH, HL, LH and LL
  
• Add standard deviation check
  

Phát hành các Ghi chú:

Added updates mentioned in the description.

Phát hành các Ghi chú:

Corrected HL and LH labels

Phát hành các Ghi chú:

Added ratios display.

Phát hành các Ghi chú:

• Previously, using pivotHigh and pivotLow on every bar for last 10 periods caused some inconsistencies in plotting zigzag. Hence, switched to points based calculation. However, zigzags are still created via lines array
  
• Fixed empty label issue
  

Phát hành các Ghi chú:

Solved array index out of bounds issue

Phát hành các Ghi chú:

Adding option to apply zigzag on different source such as RSI. This enables plotting zigzag and ratios on RSI - which can be used for finding divergence.

Phát hành các Ghi chú:

• Corrected minor logical error.
  
• Removed DeviationThreshold as it was leading to wrong calculation
