Seasonality

20 сент. 2021 г.

This is my attempt to bring an open source Seasonality indicator to TradingView.
There are still outstanding issues I couldn't figure out, so I am hoping some more seasoned Pine Script coders can take the lead from here.

What is Seasonality: https://www.investopedia.com/terms/s/seasonality.asp

How to Use

• The indicator plots the avg % change per bar for all complete years, up to 20 years back.
  
• It will only show in the daily resolution.
  
• For charts with more data, you need to scroll back a bit to get the line to display.
  
• Use Offset Adjust in the menu for charts that do not align perfectly to the start of the year.
  
• Use Smoothing in the menu to apply an EMA to the line.
  
• The panel shows YTD % gain, 5-day rolling seasonality, and 20-day rolling seasonality.
  

Known Issues

• Does not work for tickers with over 10,000 bars of data.
  
• Some tickers do not align correctly.
  
• Only works with tickers that have ~252 bars a year.
  

Areas for Improvement

• Figure out a way to use barssince() to get the precise amount of bars for each year. This will make the seasonality calculation and automatic offset more accurate.
  
• Have an option for calendar week, month, and year seasonality.
