Re-write script for buy and sell orders

As a client of Alpari I used scripts for buy or sell orders in MT4. These scripts simultaneous placed 2 other orders. One  to close the trade at a certain profit level (Profit Target) and one to close the trade at a certain loss level (Stop Loss).  The scripts also controlled  the quantity (Lots) as a part off the total equity for each trade.  Now I want to trade with LMAX but the scripts didn’t work with the demo. Someone tolld me the code had to be re-written because LMAX uses the extention  .lmx.  Can someone re-write one buy script and one sell script so that I can use them with LMAX?
