I kept buying more and they kept selling to me until I had collected all the rotation contracts and had one hundred and twenty thousand bales of cotton in hand. A few days after I bought the last bales, cotton prices began to rise. And once it started, the market always did very well - the price of cotton rose from forty to fifty points in one day. One Saturday - about ten days after I started the sale - the price of cotton began to rise. I don't know if there's still July cotton for sale anymore. I had to determine this, so I waited until the last ten minutes before the market closed. I know that is the time when traders usually sell and they can be safe when the market closes. So at the same time I placed four different buy orders, each for five thousand bales. This raised the price of cotton to over thirty points and the sale was easily completed. The market closed at a high level. All I did, mind you, was buy the last twenty thousand bales.
