Elliot Wave - Impulse

Lets dabble a bit into Elliot Waves.

This is a simple script which tries to identify Wave 1 and 2 of Elliot Impulese Wave and then projects for Wave 3.

Ratios are taken from below link: https://elliottwave-forecast.com/elliott-wave-theory/ - Section 3.1 Impulse

• Wave 2 is 50%, 61.8%, 76.4%, or 85.4% of wave 1 - used for identifying the pattern.
  
• Wave 3 is 161.8%, 200%, 261.8%, or 323.6% of wave 1-2 - used for setting the targets
  

Important input parameters

• Length : Zigzag Length. Keep the numbers low if you are looking for smaller and shorter trades. Keep the numbers high if you are looking for longer and bigger trades.
  
• Error Percent : Adjustments for ratios as it is not always possible to find exactly equal retracement ratio.
  
• Entry Percent : Once Wave 2 is formed, entry is set after reversing 30% of wave 2. This number can be increased or decreased. Caution: Keeping the number too low may result in false signals.
  
• Ignore Trend Direction: If unchecked, it will only look for pattern if Wave 1 has made a higher high. If not, it will ignore Wave 1 condition and only look at wave 1 to 2 ratio.
  
• Handle Duplicates: Since, the labels are generated upon crossover of entry price, this crossover may happen multiple times. Or sometimes wave 2 can further extend and generate new signal with same wave 1. This parameter says how to handle such cases. Keep Last is set to default and is most preferred option.
  
• ShowRatios and ShowWaves lets you display wave line and retracement ratios for each pivots
  

릴리즈 노트:

• Default error Percent set to 5
  
• Added option for waitForConfirmation - this will wait till zigzag pivot is fully formed before considering it for wave
  
• Added tightstop option which makes use of entryPercent in reverse direction.
  

릴리즈 노트:

Ok, I have rewritten the code completely to avoid errors on shorter timeframes. With this logic, target and stop labels appear only for last formed pattern. This is again done to avoid errors related to too many objects on the chart.

릴리즈 노트:

Adjust stop, entry and target label, line position based on timeframes

릴리즈 노트:

Added alert condition

릴리즈 노트:

Fix zigzag calculation error.
