The Futures Trading Glossary: 50 Terms Every Trader Should Know
Futures markets have their own language. Traders who come from stocks, crypto, or forex will recognize some of it, but enough of the terminology is specific to futures that gaps in understanding can translate directly into costly mistakes.
This glossary covers 50 terms you will encounter regularly – from account basics to order types to contract mechanics. Bookmark it, share it, and use it as a reference as you work through the rest of the articles in this series.
A
At-the-Market
An instruction to execute an order immediately at the best available price. Also referred to as a market order. In fast-moving futures markets, the fill price may differ from the last quoted price.
Ask Price
The lowest price a seller is currently willing to accept for a contract. When you buy a futures contract, you pay the ask. The difference between the ask and the bid is the spread.
Average True Range (ATR)
A technical indicator that measures the average range of price movement over a given period, typically 14 bars. Futures traders use ATR to size stops and gauge volatility relative to historical norms.
B
Backwardation
A market condition where the futures price is lower than the current spot price. This often occurs in commodity markets when near-term demand is high or supply is tight. The opposite condition is contango.
Basis
The difference between the spot price of a commodity and the price of the nearest futures contract. Basis reflects carrying costs, supply-demand dynamics, and time to delivery. It matters most to hedgers.
Bid Price
The highest price a buyer is currently willing to pay for a contract. When you sell a futures contract, you receive the bid. [Internal link: How to Read a Futures Quote.]
Bear Spread
A spread position designed to profit from declining prices. In futures, this typically involves selling a near-month contract and buying a deferred contract in the same market.
C
Cash Settlement
A settlement method where no physical commodity changes hands at expiration. The contract settles to the final cash value of the underlying index or instrument, and the difference between the entry price and settlement price is credited or debited. Most equity index and currency futures settle this way. [Internal link: Futures Contract Expiration: What Happens When Your Contract Expires.]
Clearing
The process by which a clearinghouse confirms, matches, and guarantees futures trades between buyers and sellers. CME Clearing acts as the counterparty to every trade, eliminating direct counterparty risk between individual traders.
Contango
A market condition where futures prices are higher than the current spot price. This is the normal state for most markets because it reflects the cost of carrying an asset forward in time – storage, insurance, and financing.
Contract Month
The specific month and year in which a futures contract expires. Each month is represented by a letter code: F (January), G (February), H (March), J (April), K (May), M (June), N (July), Q (August), U (September), V (October), X (November), Z (December).
Contract Size
The standardized quantity of the underlying asset covered by one futures contract. For crude oil (CL), contract size is 1,000 barrels. For gold (GC), it is 100 troy ounces. For the E-mini S&P 500 (ES), it is $50 times the index value.
Cover
To close out an existing short position by buying back contracts. Also referred to as “buying to cover.”
D
Day Order
An order that expires at the end of the current trading session if it is not filled. The opposite is a GTC (Good Till Cancelled) order.
Delivery
The physical transfer of a commodity from the seller to the buyer upon contract expiration. Most retail traders close positions well before delivery becomes relevant. Delivery obligations are enforced for traders who hold physical commodity contracts past the last trading day.
Depth of Market (DOM)
A real-time display showing the number of buy and sell orders at each price level. Also called the order book or ladder. Futures traders use the DOM to gauge short-term supply and demand and to execute entries and exits with precision. [Internal link: How to Read a Futures Quote.]
E
Equity Index Futures
Futures contracts whose underlying asset is a stock market index. Major examples include the E-mini S&P 500 (ES), Nasdaq-100 (NQ), Dow Jones (YM), and their micro equivalents (MES, MNQ, MYM). These are the most actively traded futures contracts among retail day traders.
Expiration Date
The date on which a futures contract ceases to exist. Traders who have not closed their positions before this date are subject to settlement – either cash or physical delivery depending on the contract.
F
FCM (Futures Commission Merchant)
A firm registered with the CFTC that is authorized to accept customer funds, execute trades, and clear futures positions. Ironbeam is a registered FCM and CME Group clearing member, meaning customer funds are held in segregated accounts under full regulatory oversight. [Internal link: How to Open a Futures Trading Account.]
Fill
The execution of an order. When your order is matched with a counterparty at an agreed price, you have received a fill. The fill price is the actual price at which your trade was executed, which may differ slightly from the price you saw when you placed the order.
Front Month
The nearest contract expiration that is actively traded. The front month typically carries the most liquidity and the tightest spreads. As expiration approaches, volume migrates to the next contract month.
Futures Contract
A legally binding agreement to buy or sell a specific asset at a specific price on a specific future date. Futures contracts are standardized and traded on regulated exchanges.
G
GTC (Good Till Cancelled)
An order type that remains active until it is either filled or manually cancelled by the trader. In futures markets, some brokers place time limits on GTC orders even if they are not formally cancelled.
H
Hedger
A market participant who uses futures contracts to offset price risk in an underlying physical exposure. A corn farmer who sells futures to lock in a price before harvest is a classic hedger. Hedgers are one of two primary user groups in futures markets; the other is speculators.
I
Initial Margin
The amount of capital required to open a futures position. Set by the exchange (CME Group) and adjustable by individual brokers. Ironbeam offers intraday margins as low as $50 on micro futures contracts.
Intraday Margin
A reduced margin rate offered by brokers for positions opened and closed within the same trading session. Intraday margin rates are often significantly lower than overnight margin requirements, making day trading more accessible with a smaller account.
L
Last Trading Day
The final day on which a futures contract can be traded before it goes to settlement or delivery. Not the same as the expiration date in some contracts. Traders should know the last trading day of any contract they hold.
Leverage
The ability to control a large notional position with a relatively small margin deposit. Futures are inherently leveraged instruments. A standard E-mini S&P 500 contract controls $250 times the index value – roughly $135,000 in notional exposure – for a fraction of that in margin. [Internal link: How Futures Leverage Works.]
Limit Order
An order to buy or sell at a specific price or better. A buy limit order fills only at or below the specified price. A sell limit order fills only at or above. Limit orders give price certainty but not execution certainty.
Liquidity
The ease with which a contract can be bought or sold without significantly moving the market price. High liquidity means tight spreads and fast fills. The ES and NQ are among the most liquid futures markets in the world.
Long
A trader who has bought a futures contract is said to be long. The long position profits when the price rises and loses when the price falls.
M
Margin Call
A demand from your broker to deposit additional funds because your account has fallen below the maintenance margin threshold. Failure to meet a margin call typically results in the forced liquidation of your position.
Mark-to-Market
The daily settlement process in futures trading. At the end of each trading session, all open positions are revalued at the settlement price, and gains or losses are credited or debited to the account. This is different from stocks, where unrealized gains and losses exist only on paper until you sell.
Micro Futures
Smaller-sized versions of standard futures contracts, introduced by CME Group to make futures accessible to traders with smaller accounts. The Micro E-mini S&P 500 (MES) is one-tenth the size of the standard ES contract. Ironbeam offers micro contract trading with intraday margins starting at $50.
Minimum Price Fluctuation
See: Tick Size.
N
Notional Value
The total value of the asset controlled by a futures contract. For the E-mini S&P 500 trading at 5,400, the notional value is $270,000 (5,400 x $50). Notional value is distinct from the margin required to hold the contract.
O
Open Interest
The total number of outstanding futures contracts that have not been settled or closed. Rising open interest generally confirms a trend in price movement. Falling open interest as prices rise can signal a weakening trend.
Open Outcry
The traditional system of trading in physical exchange pits using hand signals and verbal bids and offers. Most futures markets have transitioned to fully electronic trading, though the term remains part of futures market history and culture.
Overnight Margin
The full margin amount required to hold a futures position past the close of the regular trading session. Overnight margin requirements are typically higher than intraday rates. Traders who hold positions overnight should ensure their account has sufficient capital to meet overnight margin requirements.
P
Pattern Day Trader Rule (PDT)
A FINRA regulation that restricts stock traders with accounts under $25,000 to no more than three day trades per rolling five-business-day period. This rule does not apply to futures trading.
Physical Delivery
The transfer of an actual commodity upon futures contract expiration. For energy contracts like crude oil (CL), the long is obligated to take delivery of 1,000 barrels at Cushing, Oklahoma. Most retail traders avoid this by closing positions before the last trading day.
Point Value
The dollar value of a one-point move in a futures contract. For the ES, one full point equals $50. For the NQ, one full point equals $20. Knowing the point value is fundamental to calculating profit, loss, and position size.
R
Roll (Rolling a Position)
The process of closing an expiring contract and opening an equivalent position in the next contract month. Traders roll to maintain continuous market exposure without taking delivery or cash settlement.
Round Turn
One complete cycle of buying and then selling (or selling and then buying) a futures contract. Commission rates in futures are often quoted as a per-round-turn fee.
S
Settlement Price
The official closing price of a futures contract as determined by the exchange at the end of each trading session. The settlement price is used for mark-to-market calculations.
Short
A trader who has sold a futures contract without owning the underlying asset. The short position profits when the price falls and loses when the price rises. Shorting is as straightforward in futures as going long — there are no borrowing requirements.
Slippage
The difference between the price at which you expected to be filled and the price at which you were actually filled. Slippage is most common during fast-moving markets or when trading less liquid contracts.
Speculator
A market participant who trades futures with the goal of profiting from price movements rather than managing a physical commodity exposure. Speculators provide liquidity to hedgers and are the dominant participant type in equity index and financial futures markets.
Spread
Either the difference between the bid and ask price of a contract, or a trading strategy involving simultaneous long and short positions in related contracts to profit from the price relationship between them.
Stop Order
An order that becomes a market order once price reaches a specified level. A stop-loss order is used to exit a losing position at a predetermined price. In volatile futures markets, stop orders can fill at prices worse than the stop level due to slippage.
T
Tick
The minimum price increment a futures contract can move. Each tick has a defined dollar value. For the ES, one tick is 0.25 index points worth $12.50. For the MES, one tick is worth $1.25. [Internal link: What Is a Tick in Futures Trading? covers tick sizes and values for all major contracts.]
Tick Value
The dollar amount gained or lost for each one-tick move in a futures contract. Understanding tick value is the starting point for position sizing and risk management.
V
Volatility
The rate and magnitude of price changes in a market over a given period. Futures traders monitor volatility to calibrate stop placement, position size, and expected daily range. High-volatility environments can increase both profit potential and risk.
Volume
The number of contracts traded during a given period. Volume is a measure of market activity and is typically analyzed alongside price and open interest to confirm or question trend strength.
W
Working Order
An order that has been submitted to the exchange and is waiting to be filled. A working limit order is sitting at a specified price waiting for the market to reach it.
