Market data for market order (!)

I have another interesting one from Japan. The systems there have a concept in an illiquid market of the best bid or offer being a market order (e.g. the only buyt order in the market is a market buy, which they work). They like to show a code on the screen for market data that indicates this (i.e. show something other than a price). There are execution limits to ensure that this good natured soul does not get totally eaten alive.

It’s a bit different from the usual experience. Anyone have any nice ideas about how you would show this “bid” or “offer” in a market data message?

Another value for TradeCondition along with a zero price perhaps?
