Create an ADR indicator with Start/End time

I need a simple ADR indicator developed.

It would display two lines on the chart for each day historically. The top line would represent the high of the 10 day average (default setting)  and the lower line the low of the 10 day(default setting) average.  The reason I can not use a commercial version is I need a start and end time of each day that is different than the MT4 default day start/end. The inputs would be the following;

day start time : 21:15  default (means every day calculated in the average must start at this time)

Day End  time : 21:15  default (means every day calculated in the average must end at this time)

average period days: 10 (default)

Number of History days: 50 ( this draws the upper and lower average for each previous day for 50 days)

Color of upper line__

Color of lower line__

Show current range: True/False  (this will show today's current range dynamically as the day evolves. upper right corner font 8. white )

Show numeric average: True/False  (display the average value upper right corner font 8 white)

I should be able to change the times and the calculations will change accordingly. 

The calculation is simple;

take the lowest point and highest point of the each day of the past 10 days(default)  strictly within the start and end time.  then sum the 10 (default) days and divide by the average, in this case 10 days. Then draw the lines. 

NB : I should be able to load two indicator on  the same chart using different inputs without conflict
