Self matching of prices on betfair

[davidcampbell]

posting this on the snooker thread last week but it got pushed down the page so ill pop it in here for a response.....

The match at 310 is just a smoke screen, seen it happen on the horses too lately, its someone who's trading that market and wants to get an edge. Just notice how the graph on Ronnie on Betfair no longer shows the price movement because of the high match right at the start. Now someone, ;) , making his own recording can discard that early price match and still see exactly how the price has moved over time. Quite an advantage for someone only interested in trading the market.

i dont get it ... what do you mean here data? how would this help anyone? am i being thick? cheers DC

Re: Self matching of prices on betfair Yeah - I saw this on that thread too. Quite clever really...normally when you look at the history of bets in a market the graph gives you some indication of how th market is moving - a lot of people like that info when they're putting on a bet. Thing is you can really distort the vertical scale by posting and matching a MASSIVE bet compared to the normal ones. After that, the graphing software scales everything down and just shows one big spike to represent the big bet. After that, anyone betting just has no idea what the market has been up to unless they've been folloeing it really carefully. The advantage is that after doing a slef-match, you might be able to get another normal sized bet matched at odds that didn't look so attractive before. I think that was the gist of the trick anyhow...
