New Version Released

Hi,

I've posted a new version of the Java Sample that includes a new class to parse the response from getCompleteMarketPricesCompressed.

It is based on the testing release I posted last week.

The only changes from the testing version are to the display class to clean up the formatting of the sample output.

The Java Sample can be downloaded from the same link above.

Cheers,
Mark

Another new version

I've updated the Java sample to build with (and include) axis2 version 1.5.1.

This is the latest version on the axis2 site and hopefully fixes a couple of bugs people have reported.

If you want to change the version of axis2 yourself, it's not too hard. Just copy the new version of axis2's lib directory into the project lib directory and run 'ant stubs' to rebuild the SOAP proxy classes.

Between axis2 1.2 and the current version, the names of the classes for placeBets, updateBets and cancelBets changes slightly so you'll need to update the wrapper classes to handle that change. But, it's pretty obvious what you need to do.

Do you have a wrapper for cancelBetsByMarket ?

for the life of me i can't figure out how you add MarketIds to the ArrayOfInt

[gus]

ok, problem solved:

set_int

ho hum

New Version Released

Update 14/07/10: This version fixes a long standing bug in the Choose Market function where when displaying events that contained both events and markets, only the markets would be displayed.

is updating correct?

Hi Mark,

I have one question regarding your code. I play with it a bit and I managed to create a function which is calling the viewMarket every 300ms after I have selected a market. But then I am also online on Betfairs site to see if everything is correct, and sometimes it seems the viewMarket is printing wrong values, or they are updating after few secs. Do you have any idea why is this happening?

Thanks,

Hi,

It's most likely you're seeing the cross-matched prices that the Website calculates and displays.

Here's some more information:

hi Mark and thanks for the reply.

So actually the API doesnt support the cross matching feature. I read also about the algorithm that helps you be inline with the Website. But I dont understand how is possible to apply this algorithm on my side? Because I dont have the info Betfair has regarding the bets, so is almost impossible to be inline. Am I correct or I am missing something?

Hi,

Just to be clear, the API does not return the "virtual" prices, but if you submit a bet at a virtual price, it will be matched.

I'm not sure what you mean about not having all of the info about Bets. The virtual prices are calculated from the actual prices (that the exchange does return). Using the algorithm detailed in http://bdp.betfair.com/index.php?opt...=237&Itemid=68, you can recreate the prices that the website displays.

Hi Mark and thanks again for the answer.

I was confused with the virtual bets, but now everything is fine.

Hi,

I'm a beginner programmer and I'd really like to take a shot at making a program with betfair API. As such a complete sample code would be extremely helpful, unfortunately however the links in this thread do not work. Is there anyone who can help me out by posting samples that do work? I would really appreciate it. Thanks.
