David Holmberg commented on ENERGYINTEROP-725:
----------------------------------------------

If warrant represents a preference, "give me green if it is available", then what if it is not? And if you want it more than that, then it must have some additional value. It's a different product. And the value of the different products track separately. I don't see how to put them in the basket with a single market engine, Same with location. We have a single market for the feeder, but we have tags for which transformer you are located on. It makes no sense to me to try to give preference to matching tenders on the same transformer since physical electrons go where they will go no matter if you buy and sell with someone near or far. On the other hand, if the grid is down and every transformer becomes and islanded MG, then we definitely have separate markets.Â

> CTS provides a warning on segmentation and shallow markets risk with the excessive use of product warrants. I believe an actor can achieve the same behavior by extending the tender model within the same market with additional attributes that specify a preference. Therefore, the market matching engine can try to satisfy that preference without the risk of creating a shallow market.
