Trading Commodity Futures on a Central Exchange has been around for about 200 years. When Futures trading on these Exchanges was first started, it was designed to allow Commercial traders to offset price risk.
When trading Futures contracts a trader must be aware of daily price limits for the markets they are trading. There are different types of price limits in different Futures markets.
I remember a vacation in Aruba where the water was a beautiful turquoise color and you could see the bottom of the ocean, even when the water was twenty feet deep. Diving into water like this reduces the risk of an injury because you can see the ocean bottom. If this were the markets I would say it was a good risk/reward decision.
Futures markets exist for the purposes of price discovery (facilitation of trade) and transferring risk to counterparties (hedgers trading with speculators).
As markets become more global, technology for electronic trading changes, geo-political events occur, economic cycles change, severe weather conditions happen and of course we, ourselves change as we grow older.
