I would like a gambling program built, To bet on Australian racing (Horses, Harness racing, greyhounds and also Australian and overseas sports. To scrap prices from races and sport events and backing the horses or events that there has been a significant movement for them automatically on Betfair Sending me an alert of the runner or sport I will be betting on as well of the result if it won.
