As the price of the underlying commodity goes up and down, the long or short gain exponentially vs. their dollar buy in. This is why futures is dangerous, very leveraged game. If you buy a March oil contract it is for March, and thats it. UNG actually HAS to close all their nat. gas contracts out and the end of the month, regardless of if they are up or down on them(this affects prices, as UNG(simply my example, it is a ETF that tracks the price of natural gas) they must close out their contracts. Investors know this. They will try to bring prices up or down near these times(regardless of fundamentals or technicals) therefore giving it a heavy manipulation cloud over the markets for a few days. Thats a very very short explanation of whats goin on, If you want more, I can give it to you in a private message. When all these things come together, you can see why I am calling todays action bs in the main markets. Ton of head fakes going on right now.
Options trading is different. But similar. Calls and puts for the current month they are in, are all worthless if they are not "in the money". If they are in the money, they will automatically execute, unless you inform your broker otherwise. If you dont know how options work, its not hard to find a thousand places to learn. Options expiration week, offers a theory called, maximum pain. Manipulators will push prices AWAY from big losses(option houses). For instance, if SiriusXM did indeed go to 2.50 by Jan of this year, there were TRILLIONS of potential dollars worth of shares that would have to have been distributed. As this is impossible, so was SIriusXM reaching 2.50. Look up MOP. Maximum Option Pain.
