Updating the bet persistence of an existing unmatched bet

[Weeza]

Using the UpdateBet function, I am able to update either the size or the price of an unmatched bet on a horse race. But I don't seem to be able the change the bet persistence of the bet. On the Betfair website there are 3 radio buttons that let you change the persistence quickly and easily. How can I change the persistence type of an existing unmatched bet?

There is no problem to change persistence of Bet. It works

What parameters do I need to pass into the updateBet function to change the bet persistence type (and leave the size and price unchanged) ?

Damn, just checked it

    updateBets : function(cb) {
        console.log('===== updateBets for betId=%s, change bet size =====',betId);
        var bet = {
                betId: betId,
                newBetPersistenceType: "NONE",
                newPrice : "1.01",
                newSize : "5.0",
                oldBetPersistenceType: "IP",
                oldPrice : "1.01",
                oldSize : "5.0"

        }
        var inv = session.updateBets([bet])

The result is extremely strange:

{ header: 
   { errorCode: 'OK',
     minorErrorCode: null,
     sessionToken: 'removed',
     timestamp: Fri, 06 Apr 2012 15:01:53 GMT },
  betResults: 
   [ { betId: '19209544488',
       newBetId: '0',
       sizeCancelled: '0.0',
       newSize: '0.0',
       newPrice: '0.0',
       resultCode: 'BET_IN_PROGRESS',
       success: 'false' } ],
  errorCode: 'BET_IN_PROGRESS',
  minorErrorCode: null }

It's certainly bug. The call is 5 sec although market is not in-play. Please contact Betfair Team to inform them, they are certainly have problems with backends

It works now

{ header: 
   { errorCode: 'OK',
     minorErrorCode: null,
     sessionToken: 'removed',
     timestamp: Fri, 06 Apr 2012 15:19:46 GMT },
  betResults: 
   [ { betId: '19209925060',
       newBetId: '0',
       sizeCancelled: '0.0',
       newSize: '5.0',
       newPrice: '1.01',
       resultCode: 'PERSISTENCE_MODIFICATION_SUCCESS',
       success: 'true' } ],
  errorCode: 'OK',
  minorErrorCode: null }

The parameters that you used was the first thing that I had originally tried. Then I tried various other combinations which didn't work either. I tried it again now and it is still not working.

This is what I sent:
<UpdateBets>
<betId>nnnnnnnnn</betId>
<NewBetPersistenceType>SP</NewBetPersistenceType>
<newPrice>1000</newPrice>
<newSize>5</newSize>
<oldBetPersistenceType>NONE</oldBetPersistenceType>
<oldPrice>1000</oldPrice>
<oldSize>5</oldSize>
</UpdateBets>

And this is what I got back:
<n2:UpdateBetsResult xsi:type="n2:UpdateBetsResult">
<betId xsi:type="xsd:long">nnnnnnnnnn</betId>
<newBetId xsi:type="xsd:long">0</newBetId>
<sizeCancelled xsi:type="xsd:double">0.0</sizeCancelled>
<newSize xsi:type="xsd:double">0.0</newSize>
<newPrice xsi:type="xsd:double">0.0</newPrice>
<resultCode xsi:type="n2:UpdateBetsResultEnum">INVALID_PRICE_A ND_SIZE</resultCode>
<success xsi:type="xsd:boolean">false</success>
</n2:UpdateBetsResult>


The documentation only talks about being able to change the price or the size. But the old persistence and new persistence are parameters to the UpdateBets function. Can you see anything different in what I have done compared to what you have done?

[Weeza]

Also, if I call UpdateBets and change the size up by 0.01 and have a NewPersistence which is different to the OldPersistence, then the bet still goes in with the OldPersistence.

I have figured out what I was doing incorrectly.

The tag for NewBetPersistence type needed to be newBetPersistenceType. For all the other tags I correctly had a lower case letter to start with, but unfortunately I had put a capital N instead of a lower case n on newBetPersistenceType.

It is all working correctly now.

Thanks for your help AlgoTrader.
