Tradingview.com custom indicator using pine script

Job ID: 32373525

Budget: $30 – $250 USD

I'm looking for someone to create a custom chart overlay for me. It is quite simple. These are the basic parameters.
Monthly chart view
Each month can have a color background that is selected from red, green, blue, yellow.
These backgrounds will appear as vertical bars behind the candlestick chart. See attached.
I can input the data going backwards 10 years and forward up to 12-months to indicate each month's colour - eg. Sept 21 - Green; Oct 21- Red etc.
I need to be able to easily add the colours for the month's in advance - the historical months can be provided and will not need to be edited.
