It is important to understand what a futures contract is before understanding the difference between buying a futures contract and buying an asset outright. A trader who enters into a futures contract agrees to purchase or sell a particular asset at that particular price on some future date, regardless of what the price of the asset is on that date.. This is the key difference between futures and instruments where you can close a position whenever you want. It introduces a time dimension that influences almost every decision a trader makes from the moment a contract opens.
One way futures differ from more flexible derivative products is through standardization, which becomes important when traders begin comparing the different products available. Exchange-traded futures contracts specify the exact quantities and quality standards of the underlying commodity to be delivered, and have specific expiration dates. This bypasses the negotiation that would otherwise occur in private agreements, and offers the liquidity that enables these markets to operate efficiently for large numbers of participants. Another consequence of this is that traders cannot adapt the contract terms to suit individual preferences, as is possible with some other instruments, which offer more flexibility around position size or duration.
Futures trading margin requirements are somewhat different from the margin concept traders may know from other leveraged products. Exchanges typically require an initial margin deposit that represents only a fraction of the total contract value. However, futures also have daily settlement, meaning gains and losses are calculated and applied to an account balance at the end of every trading day rather than only when the position is completely closed. This daily mark-to-market process means a trader with a losing position can face margin calls much sooner than expected if they are accustomed to derivative products that settle differently.
In futures trading, expiration dates are more significant than they are with many other instruments. If a trader does not actively close or roll over a position before expiration, they may be required to deliver or accept the underlying asset, depending on the contract and which side they are on. Most retail traders have no intention of taking delivery of a shipment of crude oil or a quantity of wheat, which makes understanding contract expiration dates and rollover procedures essential rather than a technicality that can be ignored until it becomes urgent.
Contango and backwardation describe the pricing relationship between contracts with different future expiration dates. These ideas may sound intangible until a trader understands how they can impact the cost of a position they are holding over time with the help of rollovers. This expense can add up for traders that keep rolling over trades. A futures curve is said to be in contango when longer-term contracts are priced higher than their nearer-dated counterpart, and backwardation is the opposite. Knowing what type of market a particular stock is in can help to decide if a longer time frame buy makes sense.
Also, futures markets can be very volatile around major economic data releases or geopolitical developments . Futures contracts are often used by institutions to hedge real exposure to underlying commodities or financial instruments. Retail traders participating alongside these larger institutions can sometimes underestimate how much price action is driven by hedging activity rather than speculative sentiment. This can result in moves that appear disconnected from the news a retail trader is following at the time.
Getting a handle on contract specifications, margin requirements, and the expiration process generally distinguishes traders who make effective use of these instruments from those who get caught off guard, not by what the market does, but by structural features of the contract. Careful study before opening a position can help traders understand these mechanics before an expiration date or margin requirement creates an unexpected problem.
