Simple Betfair Bot

I'm looking for a Betfair bot that can monitor a specific sport and when Betfair add a new market I want it to automatically place bets so that I am first in the queue to get matched. The bot should do the following, 1. User selects a sport to monitor. 2. The bot continually refreshes the markets under this sport at user specified time intervals. 3. When any new markets appear that weren't on the previous refresh the bot will place a bet on the new market at a user defined stake and odds. Must work with Windows XP and Vista.
