Pine Script coder for Tradingview.com indicator.

I am looking for someone with experience coding with Pine Script to code a charting indicator for use on Tradingview.com. Specifically, I am looking to make a slight modification to the existing "MTPC" indicator already loaded to Tradingview.com. Currrently, the existing MPTC indicator will create a red or green box around the Daily trading range base only on the High and Low prices for each day. I would like to create an indicator that adds another slightly darker box inside that is based on the Open and Closed of each day. I have included an image of the current "MTPC" indicator as well as and image of what the "Modified MTPC" indicator should output. Please contact me with any questions. Thanks.
