Sellers can use these data to see how current price and basis levels compare to those in previous years and to detect seasonal trends in price and basis levels. Because basis levels tend to be
more predictable than general price levels, historical basis data are especially informative. Knowing the historical basis and its typical patterns throughout a marketing year and in different
locations can help farmers determine when and where to sell their crops, and, in particular, it can help them to evaluate cash bids.
