Script or indicator required to calculate average daily range of listed symbols

I need a script or indicator to calculate the following values:

• Average daily range in pips (previous 1 day)
• Average daily range in pips (previous 5 days)

The script/indicator would need to calculate these values for all symbols currently listed in the market watch window and then display the symbols and their calculated values in two columns on a selected chart window, one column for previous 5 days in one corner and one column for previous 1 day in the other corner in descending order of calculated values.

Display variables to include corner number (for each column of data), font size and font colour.
