Mansfield Long-Range Background

Mansfield Long-Range Background. From Stan Weinstein's book.

This plots the high-low range for the last N years, including the current year.

It gives us an idea of any long-term resistance or support in play, which may affect how a trend behaves.

Note that one could just as easily check the yearly chart to get what this is showing, but it's convenient to have a template with all the elements required to emulate a Mansfield chart.

Bug fix: in our main weekly use case, Pine could not determine the no. of historical bars required.

And thus this long-range indicator really is meant for weekly charts effectively, with around 10 years of data.

• Fix bug where we were missing bars in the weekly, and possibly showing things in reverse!
  
• Fix bug where there were fewer years than the lookback period configured, now it's min of lookback and available years.
  
• Explicitly error out if the indicator is on any non-weekly and non-yearly charts.
  
• Replace year labels with triangle-ups/downs, and a tooltip which shows the year, for visual compactness.

• Simplify code in parts
  
• Better logic for displaying year labels, with adjustable vertical spacing.
  
• Arrays only filled up to required lookback period at the most, now.

• Still some weird bug in yearly display, when it should be one to one with the candles.
  
• Remove use of yearly timeframes, simply sticking to the weekly timeframe, the main use case, where it works as expected.
