Indicatore per Multicharts -- 2

need an indicator to replace the Volume Profile. I have to use it for my trading system strategies with Multicharts. The input parameters must be like those already present on Multicharts. I must return the values ​​of the POC, Value Area, Upper and Lower End of the end of the volumes. Also the% of the volume of certain levels with respect to the total. I give an example. If I have a Volume Profile of the last 50 candles on SP 500 and the price range of these 50 candles goes from 4250 to 4290.5. I need to know what% volumes have been in the range from 4280 to 4290.5, or what percentage in the last 2 points of the upper end of the Volume Profile.
The data it returns to me must be able to be used for my trading system strategies.
