Reasons why you're always tired. Lack of sleep isn't the only thing sapping your energy. Little things you do (and don't do) can exhaust you both mentally and physically, which can make getting through your day a chore.
Day Trading. Futures are a popular day trading market. Futures contracts are how many different commodities, currencies and indexes are traded, offering traders a wide array of products to trade. Futures don't have day trading restrictions like the stock market--another popular day trading market.
Like all financial derivatives, futures have a finite lifespan and both parties still holding in the futures contract through expiration date is expected to fulfill the terms of the contract and either exchange the actual underlying asset (physical settlement) or the cash difference (cash settlement).
