How much to risk per trade (and how futures change the 1% rule)
How much to risk per trade? One percent of the account is the usual answer, but a fixed futures stop in dollars changes the math. Here is how.
Where "risk 1%" comes from
The 1% rule is really a rule about surviving losing streaks. If you risk 1% per trade, ten losses in a row cost you roughly 10% of the account, which is recoverable. Risk 10% per trade and the same ten losses take about two-thirds of it, which usually is not. The point was never that 1% is magic. It is that small, consistent bets make a normal bad run survivable, and a system that loses more often than it wins will hand you plenty of normal bad runs.
Notice what the rule protects against: not being wrong once, but being wrong several times in a row while your size is still large enough to matter. That distinction is the whole game.
The percentage is a tool for surviving a losing streak, not a target to hit on every trade. Pick a per-trade dollar risk you could lose eight to ten times in a row without flinching or breaking a rule, then size every trade back to that number. If a position cannot be sized down to it, you skip the trade.
What 1% looks like in dollars
Translate the percentage into money, because dollars are what you actually risk. Here is 1% of some common account sizes, next to what a single fixed $250 stop represents on each:
| Account size | 1% per trade | A $250 stop is this % of the account |
|---|---|---|
| $25,000 | $250 | 1.0% |
| $50,000 | $500 | 0.5% |
| $100,000 | $1,000 | 0.25% |
| $250,000 | $2,500 | 0.1% |
Read the right-hand column. A fixed $250 risk is a full 1% of a $25,000 account but only a tenth of a percent of a $250,000 one. The dollar risk did not change, the account did. This is the first place the tidy 1% rule meets the futures reality, and it is why the question is never "what percentage" in the abstract. It is "what percentage does my actual stop, on my actual contract, work out to on my actual account."
Why futures break the clean version
Stocks let you buy 137 shares or 4,000. You can size a position to almost exactly 1%. Futures do not work that way. You trade in whole contracts, and the smallest unit, one micro, already carries a fixed dollar value per point. On MNQ a point is $2, so a 100-point stop is $200 whether you like that number or not. You cannot trade 0.6 of a contract to fine-tune the risk to a round percentage.
That means the real sequence is backward from the textbook. You do not pick 1% and buy that many shares. You pick a dollar risk, check what one contract's stop costs, and see how many whole contracts fit under your limit. Often the honest answer on a small account is "one contract, and that is already more than 1%." The arithmetic that converts a stop into those dollars is covered in position sizing for automated futures, and it is the constraint that decides your size far more than any percentage rule does.
A fixed $250 stop, mapped to account size
The lesson is not that one of these is right. It is that the percentage is an output, not an input. Your stop is set by the market and the strategy, your account is whatever it is, and the percentage falls out of the two. If that output is uncomfortably high, the fix is a larger account or a smaller contract, not a wider mental tolerance. How much account you actually need for this is worked out in how much money you need to start.
Frequently asked questions
How much should I risk per trade as a beginner?
A common starting point is no more than 1% of your account on a single trade, and less while you are new. The more useful framing for futures is to pick a fixed dollar risk you could lose eight to ten times in a row without breaching a rule or panicking, then size every trade to that. On a small account trading one micro contract, that often works out higher than 1%, which is a sign to trade a smaller instrument or fund a larger account rather than to raise your tolerance.
Does the 1% rule work for futures?
The idea behind it works, but the clean arithmetic does not, because futures trade in whole contracts with a fixed dollar value per point. You cannot fine-tune a position to exactly 1% the way you can with shares. Instead you pick a dollar risk, calculate what one contract's stop costs, and take the whole number of contracts that fits underneath. The percentage is the result of that, not the starting point.
Why not just risk more to make more?
Because losses compound against you faster than wins compound for you, and because a system that does not need to win most of its trades will produce long losing streaks by simple arithmetic. Larger per-trade risk turns a survivable streak into a fatal one and makes it far more likely you switch the system off at the worst moment. The reward-to-risk ratio and the win rate together, not raw bet size, are what carry a system over time.
