Most of the blogs I come across are written by those who describe themselves as Betfair/Betdaq traders. There seems to be a fine line between 'trading' and 'educated gambling'. I certainly fall into the latter camp. From what I read, the effective and profitable traders are using specialist software to look for mathematical sequences and anomalies. Whilst a decent knowledge of sport is required, an analytical mind and objective calm seem to be the essential tools needed.
The process of trading seems quite dull and requiring of intense concentration. Like city trading, it seems likely that young minds would be most effective. A twenty-something is more likely than I to have the patience to create the numerous charts and analysis required, and also be able to keep concentration for long periods of trading. Whilst I have no idea how Adam Heathcote (adamheathcote.blogspot.com) makes such huge amounts consistently, his profile ( twenty-something graduate ) seems to me to be just right for succesful trading.
My own Betfair methods owe more to a love of sport and a belief that I'm smart. That's probably why my P&Ls don't look like Adam's. Yes, I do use trading techniques, and often look to get an all-green position or reduce risk by monitoring changes in odds.
But it matters to me that I think Feyenoord may not win another game this season. It matters that I think that Alisa Kleybanova should cut down her pie intake if she wants to get into the world's top twenty. Like most sports punters, I have plenty of opinions. That's why pure trading isn't for me. I like to back what I think is going to happen. And I'm just going to have to find a way of making a profit that allows me to keep having an opinion.
