The Value Square is the basis for livestock market analysis. The Value of Gain is determined by the difference in value between two weights divided by the difference in weight. From here we can derive the Value of Gain and the total Relative Value between the two.
My Market provides analysis for those markets that are not reported by the USDA. This tool will use your same Cost of Gain, Sell Weight and Sell Price, and also your specific Weight and Price to compare against.
A Bid Ticket, or Sale Barn Ticket, will give you the Bid Threshold, or maximum bid price you can pay for each weight and still cover your Cost of Gain.
