An airline that wants to trap jet fuel prices to avoid an unexpected increase could buy a futures contract that would agree to buy in the future a certain amount of ansatos for delivery at a specified price. Clearing margin are financial guarantees to ensure that companies or companies comply with open futures and their customers` options contracts. Clearing margins differ from the margins of customers that individual buyers and sellers of futures and options must pay to brokers. Hedge funds use futures to have more influence in the commodity market. They do not intend to buy, sell or interact physically with them. Instead, they plan to buy a clearing contract at a price that will make them money. In a way, they are betting on the future price of this commodity. All futures transactions in the United States are regulated by the Commodity Futures Trading Commission (CFTC), an agency independent of the U.S. government. The Commission has the right to impose fines and other penalties on an infringing person or company. Although the Commission regulates by law all transactions, each exchange may have its own rule, and under contract, companies can sanction for various things or extend the fine that the CFTC issues.
Futures contracts are often at odds with cash contacts that allow you to move to the current market price, or “on-site,” and not to a date in the future. In a spot contract, you have the same billing options as future ones. The larger the leverage, the greater the profits, the greater the potential loss: a 5 percent price change can lead an investor who has 10:1 to win or lose 50 percent of his investment. This volatility means that speculators need discipline to avoid exposing themselves to undue risk in futures trading. In this case, the corn cannon that buys the futures on the December corn in July will lose 50 cents a bushel on its futures trading, but will benefit from buying corn for only $2.50 a bushel in December on the open market. We also offer mini-futures that allow you to take a smaller position than standardized chords. Contracts are traded on futures exchanges that serve as a marketplace between buyers and sellers. The buyer of a contract must be the holder of the long position, and the seller must be the holder of the short position.  Since both parties run the risk that their counterparty will go away if the price is against them, the contract may lead both parties to register part of the value of the contract with a mutually trustworthy third party.
For example, in the gold futures market, the margin varies from 2 to 20% depending on the volatility of the spot market.  The expiry (or expiry in the United States) is the time and date on which a month of delivery of an end contract terminates trading, as well as the final settlement price of that contract. For many stock index and interest rate contracts (as well as for most stock options), this occurs on the third Friday of some trading months. On that day, the futures contract for the previous month becomes the previous month`s futures contract. For most CME and CBOT contracts, March futures become the next contract.
