Developer needed to add a function to find lotsize based on ADR

Developer will create a function in mql4 to calculate the lot size based on current ADR. 

For example the ADR is 50 pips, I need to calculate the lotsize based on this price movement to make 2% of my account on 50 pips. 

Once the lotsize is calculated it will be divided into (x) number of orders. The orders need to be the same size to satisfy FIFO rules. 

For example if the lotsize is .09 it will be 3 orders at .03 each

Or if its .25 it will be 5 orders at .05 each etc

I want to be able to set the cap of number of orders so I am not entering 25 orders of .01 to satisfy a lotsize of .25

For example no more than 10 orders per pair.

I also do not want the calculations to require a stoploss.
