I only trade the Over 2.5 Market when I am able to see the game live on TV. I am very careful in my choice of games, and enter the market at different stages of the game depending on what I see. I am reasonably successful and that is why I persevere with it, however, all my efforts at automation have come to nothing. The suspension is unquestionably no friend. The markets are suspended about five seconds earlier than any possible reason for this suspension is visible on my HD TV screen and this leads to false hopes of a goal being scored. I think I have counted as many as five suspensions without a goal in a period of play.
The market may be suspended simply because of Betfair losing their feed to a game. I call the guy who suspends the market "The Betfair Dummy" and that accurately reflects my views of his competence. Any suspension screws up the automation of this market as it takes time for the market to form again and this time can vary enormously.
I use another proprietary software for my trading in this market and a sound resembling a fire siren is made at suspension. I love to hear this sound when goals are due to be seen on my TV but it can be very frustrating when the dummy suspends for non-valid reasons.
If the market was only suspended when a goal was scored, automation would be achievable and useful and I would work harder to implement this. As things are, I consider automation of this market to be far too risky.
As a general point, not one directly related to the subject of this thread, I will say that I tend only to back Overs and mostly when the odds are high ( To me anything over 2.3 at kick off is counted as high.) I cannot understand how anybody can say with certainty that there will be less than 3 goals in any game. The higher the odds they offer, the more attractive is the price as far as I am concerned. When all is said and done, the objective of a football team is to score goals.
