Create indicator based on math equation

hello

i have a sample math equation i want to turn it to indicator work on any time frame .

the equation is sample  :

DOB= low of the candle minus (-) the square of the low , for example if the low is 27000 then the square will be 164.31 , so it will be 27000-164.31 =26,835.68 , so this is DOB.

PRD= pivot point ( HIGH+LOW+CLOSE / 3 ) MINUS (-) range , range mean square the low multiply 2 , so in our example will be  328.62.

so DOB-PRD=number 1.

UPB= high of the candle plus (+) the square of the high , for example if the high of the candle is 27000 then the square will be 164.31 , so it will be 27000+164.31 =27,164.31 , so this is UPB .

PRU= pivot point ( HIGH+LOW+CLOSE / 3 ) plus (+) range , range mean square the high of the candle multiply 2 , so in our example will be  328.62.

so UPB+PRU=number 2

NOW , number1 minus number2 will be the reading of the indicator and the indicator i need it histogram like MACD .

maximum two days working .
