simulated pricesEach contract below is a commodity price index the demo simulates: 100 on the day it was listed, moved by this contract's GDD and by a simulated market factor. Weather-implied is the price at the index this market is trading at now; when it differs from the asset's own market price, simulated spread traders trade the two against each other.
