What Is Futures Trading? How Contracts, Margin and Tick Values Work

The fastest way to understand futures is to follow the dollars. A futures contract is a standardized agreement to buy or sell something at a set price on a set date, and for the contracts day traders use, a price move in the underlying becomes a fixed dollar amount per point. If you know the multiplier, you know what a mistake costs.

How a futures contract works

When you trade ES, the E-mini S&P 500, you aren't buying shares. You hold a contract that tracks the index and settles in cash at expiration. Each index point is worth $50. At a hypothetical index level of 4,450, one contract has about $222,500 of notional value, but you post margin, a performance deposit, not the full amount. Margin is collateral, not a limit on loss. A fast move can lose more than you posted, and exchanges and brokers change margin requirements as volatility changes.

Core contracts and their values

Micros exist for most of these. Starting with MES or MNQ lets you practice with real mechanics at one tenth of the exposure of the standard contract.

A worked ES trade

This is a hypothetical example. You buy one ES at 4,450.00 and price moves to 4,460.00. That's 10 points times $50, or $500 gross. Subtract an assumed $4 round-trip commission and you're at $496. Had price moved against you to 4,444.00, the unrealized loss would be 6 points, or $300. Real fills may differ from the planned price, especially in fast markets, so stops can slip. Before you enter, you should already know the stop, the dollar risk and the reason for the trade. See position sizing for futures traders.

Futures versus stocks

• Day-trade rule: FINRA's pattern day trader requirements for securities margin accounts have been replaced by intraday margin rules effective June 4, 2026, with brokers allowed to transition through October 20, 2027. Some brokers may still apply the old rules in the meantime, so check your broker's current policy and see the Investor.gov glossary entry. Futures accounts aren't governed by that securities rule. They have exchange and broker margin requirements, and your broker or firm sets its own minimums.
• Hours: Regular US equity cash hours start at 9:30am ET. Equity index futures on CME Globex typically trade Sunday to Friday from 5:00pm CT with a daily break, so news outside stock hours can move futures. Check CME's schedule and holiday notices.
• Shorting: Selling a futures contract doesn't require borrowing shares, so there's no locate step. Margin and rules still apply.
• Leverage: It's built into the margin structure. The exposure per dollar of margin is large, which is why oversizing ends accounts. Margin is collateral, not a cap on loss, and stop orders can slip.
• Costs: Commissions, exchange fees, data fees and platform fees all vary by broker and change. Add them up for your own setup.
• Clearing: Contracts clear through a central clearinghouse, which reduces counterparty risk between traders. It doesn't remove broker or operational risk.

Tax basics

Regulated futures contracts that qualify under Section 1256 are generally marked to market at year end and taxed 60% long-term and 40% short-term, regardless of holding period, subject to eligibility, elections and exceptions. That's different from stocks and options in general, and it isn't a blanket rule for all trading income. The IRS describes it at About Form 6781 and Topic 429. Trader status is fact dependent, and expense deductions are conditional. Talk to a qualified tax professional about your situation.

What you need to start

• A broker that offers futures, or a prop firm account whose rules you've read. Compare commissions and fees directly with the broker's current schedule.
• A platform. NinjaTrader 8 is a common desktop choice for futures and supports simulation. TradingView is widely used for charting. See NinjaTrader 8 vs TradingView and the NT8 beginner guide.
• A market data feed, which may be bundled or billed separately.
• Risk capital sized to your stop. Work it backward: pick a risk per trade, divide by dollars per contract at your stop, and see what account size makes that comfortable. How much money to start trading futures covers it.
• A written strategy with entries, exits, stops and size. The edge calculator helps check whether the reward-to-risk math can work.

Mistakes that end accounts

1. Oversizing. Hypothetical: one ES on a $5,000 account and a 20-point adverse move costs $1,000, which is 20% of the account. Use micros until size fits your risk.
2. Trading without a stop. Without a defined exit, a bad move has no limit except your margin.
3. Trading through scheduled news without a plan. Spreads widen and stops slip. See the FOMC guide.
4. Changing strategy after every loss. You can't evaluate a plan you keep rewriting. See common trading mistakes.
5. Not keeping a journal. How to journal futures trades.

A practical path

Practice in a simulated account first, to learn order types and platform mechanics. Simulation doesn't reproduce live fills or the pressure of real money, so treat it as practice, not proof. Learn how market conditions change which strategy type fits (market regimes), then go live with micros. If you want a structured course, daily ES and NQ Key Price Levels and a community, the Intro plan is $97 a month after a 7-day trial: start the trial.
