I need to know oscillation of the pistachio nut in order to understand profitability, sustainability of the farm. It is very hard to see the wholesale prices - when trading companies are buying from farmers. And it is also hard to find the websites on which people are selling farms. I hope you can help either with your knowledge of wholesale prices (cca) or perhaps with agencies that are selling the farms.
