How to Trade Futures

To trade futures, start from the contract specification: tick size, tick value, expiry and margin. The margin is a performance deposit rather than the position's cost, so a small account controls a large exposure and the position size has to be chosen from the tick value.

A futures contract is a standardized agreement to buy or sell something at a future date. You post a deposit rather than the value, which is why a modest account can control a large exposure — and why the specification matters more here than in almost any other instrument.

Before you start

The tick value of the specific contract, because it converts movement into money. Every contract has its own, and it is the number that turns a chart distance into a currency amount.

The contract’s expiry and roll schedule, since the position does not last forever. Contracts end. Holding a view past that date requires moving to the next one.

An understanding that margin is a deposit, not the cost of the position. The exposure is the contract’s notional value, which is many times the margin posted.

The steps

1. Read the contract specification first

Tick size, tick value, contract months, margin requirement. Four numbers, published by the exchange, and they differ for every product.

2. Convert a move into money

Distance in ticks multiplied by tick value gives the currency amount. Until you can do that instantly for your contract, you cannot size a position in it.

3. Start with the smallest available contract

Most liquid products now have micro versions at a fraction of the standard size. Learning the mechanics on the smaller one costs a fraction as much per mistake.

4. Size from the stop distance, not from the margin

Risk figure divided by stop distance in ticks divided by tick value. The margin requirement tells you what the broker permits, which is a different question.

5. Know your roll date

Liquidity moves to the next contract before expiry. Holding a view across that boundary means closing one position and opening another, at the cost of a spread each time.

6. Treat overnight sessions as real

Futures trade almost around the clock, which reduces gap risk and introduces long thin stretches where the spread widens and a stop can fill badly.

7. Never let a position reach the margin call

A margin call means the broker is closing the position on their terms. Your own stop should have fired a long way before that, and if it could not, the position was too large.

How to tell it worked

All 4 specification numbers were read before the first trade in that contract.

Position size came from tick value and stop distance, not from the margin requirement.

The roll date is known, and 0 trades were held into the final 5 days of a contract.

And 0 margin calls occurred, because your stop was always the binding constraint.

Why margin is the most misread number

It is a performance deposit. It exists so the exchange can cover an adverse move, not because it is what the position costs. The exposure is the full notional value.

Which is where the leverage in futures actually comes from. Nothing is borrowed and no interest is charged; the size is simply much larger than the cash committed, and the loss scales with the size.

What leverage does to the numbers

The loss scales in full. A contract controlling $100,000 on $10,000 of margin is 10x leverage, and a 10% move against it takes the whole $10,000.

The gain does not scale as cleanly when exposure is held at a constant multiple. The standard approximation for the growth rate is L × r − (L² − L) × σ² / 2. Say the underlying grows 8% a year at 15% volatility: twice the exposure grows at roughly 13.75% a year, not 16%, and three times at roughly 17.25%, not 24%. The returns fall short of the multiple while the losses do not.

That gap is the arithmetic of compounding through losses, and it is the reason leverage is not a free multiplier. It is reproducible, and it applies to any leveraged exposure including this one.

Worked example from this page: an underlying growing 8% a year at 15% volatility, with exposure held at a constant multiple, grows at roughly 13.75% at 2x rather than 16%, and 17.25% at 3x rather than 24%.

Which contract to actually trade

Liquidity first, and it is not close. A handful of index, energy, metal and rate contracts carry the overwhelming majority of the volume, and everything else is materially harder to get in and out of.

Then contract size against your account. A standard index contract can represent a very large notional value; the micro version of the same product is a tenth or less, with the same specification structure.

Then the session that suits you. Different products are most active at different hours, and trading a contract during its quiet stretch means paying a wider spread for no reason.

Ignore the rest until those three are settled. The temptation with futures is breadth — dozens of markets, all accessible from one account — and the cost of that breadth is trading products whose specifications you have not read in sessions where nobody else is present.

The original data

Of the 24,971 unique videos in this site’s search study, 593 mention futures in the title, at a median of 5,594 views across 358 channels, and 45% of those titles are instruction-shaped. Options trading appears in 337 at 18,124 and leverage in 55 at 36,446. Repeat appearances of the same video count once.

593 videos at 5,594 across 358 channels. Heavy coverage and a modest audience per video, and very little of it starts from the contract specification — which is the one thing that differs from trading anything else.

The question: Margin allows 8 contracts. Trade 8?

The answer is that margin is not a position size. It is the deposit the exchange requires — and sizing to it means the loss on an adverse move is whatever the contract happens to be worth rather than the amount you decided to risk.

When it fails

The failure is sizing from the margin requirement, and futures make it unusually easy. The account shows what it can support, that number is much larger than a cash position would allow, and it feels like a limit rather than a deposit. A position taken at that size has a loss per tick many times what the account can absorb, and the first genuinely adverse session produces a margin call — at which point the broker closes the position, at their timing, at whatever price is available.

The second failure is not knowing the tick value. You cannot size without it.

A third is missing the roll. Liquidity leaves before expiry.

A fourth is starting on full-size contracts. Micros exist for learning.

A fifth is trading the thin overnight stretch. Spreads widen substantially.

And a sixth is treating leverage as a clean multiplier. Losses take all of it; gains fall short.

Futures contract covers the specification field by field. Micro futures is the smaller size worth starting on. And margin account explains what the deposit actually is.

What I actually do

The specification is the whole first lesson. Tick size, tick value, expiry, margin: four numbers per contract, and without them you cannot say what a one-point move is worth or how much is actually at risk. Everything else in futures is ordinary trading, and that part is specific.
