Automating Betfair - a blog about Gambling and Technology
- skolor 17y agoTo make sure I understand this, BetFair is a simple betting platform. People make bets, and other people take those bets. What he proposes to do is play both sides of an event, and hope that some takes both of them. That way, regardless of the outcome, he turns a small profit.If I understand this right, he's basically just doing arbitrage on the betting market.
- dood 17y agoHe explores various strategies for using Betfair other than arbitrage, outlined here [http://automatingbetfair.blogspot.com/2010/02/four-trading-strategies.html http://automatingbetfair.blogspot.com/2010/02/four-trading-s...] He also notes that simple arbitrage opportunities have long been exhausted [http://automatingbetfair.blogspot.com/2010/02/betfair-bots-and-opportunity-out-there.html http://automatingbetfair.blogspot.com/2010/02/betfair-bots-a...]
- joshu 17y agoPretty interesting reading (my group at MS did automated market making.) Did this make anyone else cringe? > In addition: an SQLite database, sitting in a Dropbox directory, can be used by different instances and computers in different locations, running atop different platforms.
- mahmud 17y agoReally horrible "architecture" there.
- d4ft 17y agoHa. The disaster alarms were ringing loudly in my head. Josh- I assume MS means Morgan Stanley, not Microsoft. If so, do you think all the sorts of problems we see financial organizations taking advantage of could be applied to gambling markets. That is, does Miller's contention that finance would not exist without transaction costs apply equally to gambling? If so, is gambling just another form of an options market? And finally, should gambling be treated like any other market with buy and sell prices (like commodities or bonds)?
- joshu 17y agoSo, I haven't thought about your premise at all. So this is off the cuff. I think that gambling about real-world events (election outcomes etc) can be a kind of futures market and are a valid kind of market. I'd want to be able to hedge against elections and so on. Manufactured events (horse racing?) and raw probability (die rolls) are probably not valid markets, IMO. Personally, I think that the problems we see because of financial organizations misbehaving are due to regulatory issues rather than structural issues.
- d4ft 17y agoOh, I definitely wasn't passing judgment on financial firms. By "problems", I meant reducing transaction costs by bundling and/or securitizing. I was more referring to the general problem being that capital markets are not perfect (in the economic sense). The real question is how one would actually perform a hedge in a gambling market. I guess, what it comes down to, is 1) are there hedging opportunities and 2) if not, why not?
- regularfry 17y agoI don't think he means concurrently. At least, I really hope not.
- dedward 17y agoArbitrage opportunities exist in most markets, and while they may be seen as a drain on the system - ultimately they have the net effect of keeping markets sensible. THere's no free ride.... if people are making a killing on some arbitrage gap (whether on the global economic markets, or betfair, or multiple offshore gambling sites) - the market will eventually correct for it as the arbitrage activity becomes part of the market. There's no free ride.
