People in the commodity industries use these markets to set real prices - When Joe the Day Trader can buy futures of oil and cotton but knows that they'll never actually take possession of a barrel or bale, like people in the industry do, it ruins the nature of a market.
2008 put me out of the cotton business with an inverted run. The market ran up, farmers fixed their contracts with us at those high prices so in theory, since this is a market, we should be able to sell that cotton to a producer around the same price, plus mark up for delivery. Except the Mills said, eff that, that's not a real price, no sale. The bank called in their note and our company went out of business.
For us, it all started when day traders were able to access our trading system, called ICE, which threw the NYCE in to a spin. Before then, actual traders on the floor of the NYCE traded on the floor, afterwards, all trading was done electronically meaning anyone could buy in the market. The cotton market had a 300 limit that was in place to prevent crazy runs and crashes. If the 300 was hit, the market was shut down for a period of time, back then I believe it was the whole day. We thought the next day the market would open at the same price but thanks to all of the orders that were pending, the market moved theoretically overnight and opened at a much higher price than what we knew to be possible and then reached the day two 300 point limit to shut the market down.
From March 3-5th the market jumped ~50 cents - 5000 points. Before then we were under the impression the most it could move was 900 points over a 3 day period. We should be able to sell the cotton at a price around the futures market for delivery but these weren't real prices so farmers could set their price but we couldn't sell it to a consumer.
Here's a decent article on it - I wish WAREAGLE was around - He could write a book on those 3 days.
