Note di rilascio:

v2 - To avoid Error: Study references too many candles in history, set max candles to 1000.

NOTE: If you cannot see beginning boxes, tradingView (tV) has garbage disposal service, so after drawing max number of boxes, it will start to delete old ones to accommodate new ones in FIFO method i.e. First In First Out(delete).

v6 - Fixed a bug where lowest and highest were sometimes not being updated correctly. Had to reset them after each box drawing.

Note di rilascio:

v7

• Cleaned color part of the code - It is a separate function and less lines of code
  
• Added error check so it removes blank spaces from color input i.e. spaces after comma separated colors do not result in error
  
• Added option to choose which boxes to display, you can choose "both" to display earnings and custom boxes, or select either to display as stand alone
  
• Just to clarify - Custom box input takes dates in form of yyyymmdd. Each two dates next to each other represent a range.
  e.g. 20210601,20210901,20220101,20220201 - This represents three time periods, one from Jun2021 to Sep2021, the next as Sep2021 to Jan2022, and last as Jan2022 to Feb2022
  For the colors as there are 3 time periods, we need to input only 3 colors (even though 4 dates are specified), e.g. green, clear, purple - This will color first time period in green, next as blank, and the other as purple
  So if you input the color as "clear" it will not highlight that period which can be used to ignore periods between input dates
