Talk:Betting exchange

message: At present, the list is:
BETDAQ
Betfair
Betsson
TradeSports
This list seems fairly arbitrary to me. I can understand Betfair being included, seeing as though it's the industry leader and maybe Betdaq as there's general consensus that it's the next biggest competitor but where do we draw the line from here? Why isn't WBX included for example? I would argue that this exchange has more liquidity than Fasbet, Betsson and Tradesports. I'm tempted to draw a line through all the smaller exchanges and just leave the two biggest ones up but is this fair and is it useful to Wikipedia members to do this? Another option is to just include the DMOZ listing for gambling sites but this list has not been actively maintained and is in a derelict state. It is also fairly irrelevant to betting exchanges. Please comment if you have time. Cheers Wayniac (talk) 23:33, 1 April 2009 (UTC)
replies: text: Those are not external links.  They are internal links to Wikipedia articles.  If a betting exchange is notable enough to have an article, then it could be a see also.  At the point the see also list becomes too extensive it could be removed completely.  In this case we have eight betting exchanges that have articles so I'll remove the specifics and add a link to the category instead. 2005 (talk) 01:34, 2 April 2009 (UTC)
replies: text: Yes, my bad on calling them external links but the underlying issue still needed resolving. Good outcome, thanks. Wayniac (talk) 07:51, 2 April 2009 (UTC)

message: http://www.alexa.com/data/details/traffic_details?&range=max&size=medium&compare_sites=&y=r&url=betfair.com shows that traffic to betfair.com has halved in the first 6 months of 2006.  Does this indicate that betfair.com no longer owns 90% of the market?  Has an competitor taken a lot of their market?
:I figured I'd reply to this old query. The 90% market share figure was crudely estimated by betting industry commentators some time in 2005 and it appears to have stuck. There's no way of knowing for sure just how dominant Betfair is (e.g. the number of members depends on one's definition of 'active' members, matched betting figures contain artifacts such as market-making services and trading at low prices) but the 90% figure still seems sensible enough today. --Wayniac (talk) 07:51, 2 April 2009 (UTC)

message: Almost everybody refers to the Betting Exchanges as such - and not a "Bet Exchange" as referred to in the title.
Shouldn't this entry be re-labelled to "Betting Exchange"? —The preceding unsigned comment was added by Hne123 (talk • contribs) 11:46, 9 February 2007 (UTC)
replies: text: It looks like an anon editor changed it in 2003, and nobody has done anything about it till now.  Betting exchange is obviously the common term, so switching the redirect makes sense. 2005 12:10, 9 February 2007 (UTC)

text: Can someone please change the name back to "Betting Exchange"? I'm wary of creating a re-redirect as "Betting Exchange" currently redirects to "Bet Exchange". Also, I'm not sure how to bulk change the pages that link to "Bet Exchange". Hne123 15:47, 9 February 2007 (UTC)

message: I am not going to edit the page, it is none of my business. But the following statement in the Traders section may need to be updated:
 "The profit or loss for a trader will typically be no more than 10% of the total amount of his combined back and lay stakes." 
Exchanges such as Betfair are quite efficient now and the 'overround' (which is the p&l on a balanced book) is typically less than 2% when liquidity in the market is high enough for a trader to be able to reasonably expect to take offsetting positions. BUT If you know of somewhere where the overround is in the region of 10% PLEASE LET ME KNOW! I wan't in on that action!!!

text: You misunderstood. The author is not suggesting that traders price up 110% / 90% markets and their bets somehow get matched on either side for a guaranteed profit. Traders take small positions at different points in time in the hope that the market moves favourably, allowing them to 'trade-out' (often many times on the one market) for a profit that is typically less than 10%.

replies: text: No, you misunderstand.  It is perfectly possible to make markets on a betting exchange precisely in the way you say they do not.  Of course, other trading activity is posible too.  Paul Beardsell (talk) 06:37, 30 April 2009 (UTC)
replies: text: Of course it's possible to make markets in this way but good luck getting bets matched on either side! Wayniac (talk) 06:50, 30 April 2009 (UTC)
replies: text: No, market making is done on betting exchanges in precisely the same way as it is done on stock exchanges.  Paul Beardsell (talk) 15:36, 13 May 2009 (UTC)

message: This article has an interesting take on betting exchanges but it is WP:synthesis and reflects a particular WP:POV.  Needs a re-write.  Paul Beardsell (talk) 06:34, 30 April 2009 (UTC)
replies: text: Totally agree with you. This meandering article needs to be culled and the key concepts clarified. I also think that there's a lot of general information about betting exchanges in the Betfair article that could be merged to this one. Specifically, 3/4 of the lead-in text and most of the "Controversy" content is of a general nature. Wayniac (talk) 06:57, 30 April 2009 (UTC)

message: Wouldn't intrade.com be an example of a betting exchange?   If so, it ought to be mentioned:  it's much better known than Betfair outside the UK.   Grover cleveland (talk) 03:41, 1 January 2012 (UTC)
replies: text: Intrade tends to be seen (and wants to be seen) as a 'prediction market' rather than a 'betting exchange' which is why it is typically only briefly mentioned when during the discussion of betting exchanges. 109.157.218.219 (talk) 22:12, 9 February 2012 (UTC)
