CancelOrders confusion

[McTash]

Hi all,

Just checking that using the CancelOrders request I should be able to outright cancel an unmatched bet without specifying a size.

Currently when I try (defining the market id and a CancelInstruction with the bet id but no size) I get an INVALID_BET_SIZE error in the instruction report.

Am I doing something incorrectly? Is it possible to cancel a bet without specifying the size you wish to cancel?

Many thanks

EDIT: here is the json

Calling: SportsAPING/v1.0/cancelOrders With args: {"marketId":"1.110110228","instructions":[{"betId":"28318383804","sizeReduction":0.0}],"customerRef":null}

Perhaps the size reduction should not be there at all?

EDIT: Ok that was the problem.

In case this is useful for anyone else, I have expanded the c# sample code (split it into individual requests suitable for throttling) and implemented a lot of the types that are not present in the sample code. In this case sizeReduction was specified as a double. Changing this to double? (nullable) allowed the serializer to strip the parameter rather than passing it as 0.0 which caused the error.

i don't think it should.

in my test app I just send the marketId and the list of betId(s) to cancelOrders/and it seems to work fine, tho I've probably only used it half-a-dozen times.

ooops, sorry, didn't notice your EDIT
