Futures Risk Management: 7 Rules and a Position-Sizing Formula

Most blown futures accounts have the same story: too many contracts, no defined exit, and a loss that turned into a bigger loss. Risk management is the part of trading you control completely. Losses can exceed your initial deposit, and these principles do not guarantee any outcome.

Rule 1: Define risk per trade before you enter

Pick a maximum dollar loss for any single trade, often a small percentage of the account. Decide this before you look at the setup, so the setup can't talk you into more.

Rule 2: Know where you're wrong, and set the stop first

A stop is the price at which your idea is invalid. Place it where the trade thesis fails (below a key level for a long, above for a short), not where it's most convenient for your size.

Rule 3: Size the position from the stop

Contracts = risk per trade ÷ (stop distance in points × dollars per point), rounded down. This example is hypothetical.

• Risk per trade: $150
• Stop distance: 12 points on NQ ($20 per point) = $240 per contract
• $150 ÷ $240 = 0.62, which rounds down to zero NQ
• Switch to MNQ ($2 per point): 12 × $2 = $24 per contract; $150 ÷ $24 = 6.25, so 6 MNQ

See the tick value chart for other contracts.

Rule 4: Set a daily loss limit

Choose a maximum loss for the day. When you hit it, stop trading. A hard daily limit prevents one bad morning from becoming a bad month.

Rule 5: Respect that stops aren't guarantees

Fast markets, news events and thin overnight liquidity can cause slippage, a fill worse than your stop price. Allow for it in your sizing, and avoid holding oversized positions through major scheduled events.

Rule 6: Don't average down or widen stops

Adding to a losing position or moving a stop further away turns a defined risk into an undefined one. If the thesis changes, exit and reassess.

Rule 7: Journal every trade

Record the setup, reasoning, entry, stop, target, result and one lesson. Review weekly. A journal is how a loss becomes information rather than just a loss.

Margin is not a sizing tool

Your broker's margin requirement tells you the minimum to hold a position, not how much risk is sensible. Never use the most contracts that margin allows as your size.

A pre-trade checklist

• Thesis in one sentence
• Entry, stop and target defined
• Dollar risk within my per-trade limit
• Contract size calculated from the stop
• Daily loss limit not reached
• No major news event imminent, or I'm sized down

How this connects to trade ideas

When you follow a published idea, risk management is still yours. The idea gives an entry area, a thesis and a level where it's wrong; you decide size to fit your own account and limits.
