ListMarketBook - missing prices

[NFLMAN]

I've noticed that the data returned from ListMarketBook will sometimes have no data in the 'AvailableToLay' section for some soccer match odds markets. It just returns an open and close square bracket where the prices should be. I can understand this being the case where there are no prices available to lay but this is happening on markets that have a full quota of lay prices. Has anyone else noticed this?

For example, Belgium v Russia on 22nd June is returning no lay prices for the home win....

Are you rolling up prices? If so, what have you set the roll-up stake to be?

I was under the impression that the call would only return the odds if there was sufficient money on the market to cover the roll-up stake. So, if your roll-up stake was £200 and there was only £100 available on the market then you would get no prices.

[NFLMAN]

No, I'm not rolling up any prices. I'm just requesting the lay prices. This is my call:

GetListMarketBookRequestString = "{""marketIds"":[""" & MarketID & """],""priceProjection"":{""priceData"":[""EX_BEST_OFFERS""]}}"

Have you tried looking at the same markets using the Visualiser?

[NFLMAN]

Yup, looks fine in the visualiser.

The text file that is returned does not have the prices though. Strange why it only happens on one or two markets out of around 500 ???
