Need a Custom Code for my EA Builder (Money Management)

Hello, 

I currently use http://www.eabuilder.com to build my EA's. Due to my most recent trading strategy and in order to be complaint with new FIFO rules in Oanda, I need a Custom Code in the Money Management section with the following characteristics:

- Current EA has up to 3 Maximum simultaneous open trades, these trades MUST be of different sizes (lots) at all times and cannot be the same 

- Ideally, the first trade in the sequence would be say 0.1 LOT, second 0.2, third 0.3, and the fourth would go back to 0.1, fifth 0.2 and so on. 

Hopefully this is rather simple. Basically I need a revolving Fixed Lot arrangement to optimize my strategy and be in compliance with new requirements. Price is negotiable. 

Thanks for the help,

Kamil
