LIMIT_ON_CLOSE not working?

[bf123]

I have tried placing LIMIT_ON_CLOSE bets on horses and greyhounds and they come back with the same response.

I am playing around with LIMIT_ON_CLOSE because I thought that would let me place bets which would only be matched at that price instead of been matched at a price near to it.

Request:

{
	"marketId": "1.131162865",
	"instructions": [{
			"orderType": "LIMIT_ON_CLOSE",
			"selectionId": 10570272,
			"side": "BACK",
			"limitOnCloseOrder": {
				"size": 2.0,
				"liability": 10.0
			}
		}
	],
	"customerRef": null,
	"locale": null
}

Response:

{
	"faultcode": "Client",
	"faultstring": "DSC-0018",
	"detail": {}
}

Thanks

A limit on close order has parameters called "price" and "liability", not "size" and "liability".

Try changing your "size" to "price".

For a back bet, the price is the minimum odds at which you should be matched.

For a lay bet, the price is the maximum odds at which you should be matched.

Thanks for that, I had looked at the api documentation but did not notice the parameters were different until looking at it again after your comment

I was using the BetFair sample code for C#. I have looked it again and it seems to still have the wrong parameters.
