Need to develop an simple Value averaging algo

Hi,

I need a simple algo to be developed.
it will place order based on value averaging

example as below

Final Target amount :- 600000
Daily target amount as below :-

10000
20000
30000
40000
...
...
600000

it will invest amount based on total current value - todays targeted amount
lets say today amount should be 40000 but our current value of all trades shows 50000 then it will not do any trade
if its 35000 then it will invest only 5k as difference

So this is the basic concept , rest we can discuss

let me know if any one can do it.
regards
