The myth: a small account cannot compound its way anywhere in reasonable time, so the only rational move is to use the leverage futures already give you. Trade bigger, get there faster, then dial the risk back once the account is a real size. Conservative sizing is a luxury for people who already have money.
The test: one genuinely good system — 45% win rate, 2R winners, 0.05R of costs, an expectancy of +0.30R per trade — run at nine risk levels from 0.5% to 20% of equity per trade. 30,000 accounts each, 200 trades each. And one rule the pure-maths version of this argument always omits: trading stops if the account is ever 30% below its high.
That rule is not an editorial choice. Every account has one. A funded account has it written in the contract. A personal account has it written in a spouse, a mortgage, or the moment conviction runs out. Simulations that ignore it are answering a question nobody is actually asking.
The answer without the rule, which is where the myth comes from
If you ignore the stop-trading line and allow every account to run all 200 trades no matter how deep the hole, more leverage does look better for a long way. The median account at 10% risk ends at $460,941 against $17,807 at 1%. That is the arithmetic the myth is built on, and it is not fake — it is the Kelly criterion doing exactly what Kelly says it does.
It is also completely unavailable to a human being, for a reason visible one column to the right.
| Risk per trade | Median max drawdown | Accounts that ever hit −30% |
|---|---|---|
| 0.5% | 5.1% | 0.0% |
| 1% | 10.2% | 0.0% |
| 2% | 19.5% | 7.5% |
| 3% | 28.2% | 40.7% |
| 5% | 43.4% | 94.1% |
| 7.5% | 59.5% | 99.9% |
| 10% | 71.7% | 100.0% |
| 15% | 87.3% | 100.0% |
| 20% | 95.8% | 100.0% |
Same +0.30R edge in every column. 30,000 accounts, 200 trades each.
At 2% risk, 7.5% of accounts touch a 30% drawdown. At 5% risk, 94.1% do. At 7.5% and above it is effectively certain. The edge never changed. Only the size did.
The answer with the rule
Now re-run everything, and end an account's trading the first time it is 30% underwater. This is the number that describes what happens to actual people.
Same system, same edge, same 200 trades. Only the risk per trade differs.
| Risk per trade | Median outcome with the rule | Median outcome ignoring the rule |
|---|---|---|
| 0.5% | $13,421 | $13,421 |
| 1% | $17,807 | $17,807 |
| 2% | $30,304 | $30,304 |
| 3% | $41,300 | $49,333 |
| 5% | $16,653 | $114,848 |
| 7.5% | $12,419 | $261,016 |
| 10% | $10,730 | $460,941 |
| 15% | $9,980 | $694,128 |
| 20% | $8,675 | $407,673 |
The median outcome peaks at 3% risk and then falls off a cliff. At 5% it is $16,653 — worse than the 2% column. At 10% it is $10,730: the median leveraged trader with a genuinely profitable system finished roughly where they started, because the account was shut down at −30% long before the 200 trades were up. Every single account in that column hit the limit. At 15% and 20% the median account ends below its starting equity.
More leverage did not buy a riskier path to the same place. Past a modest point, it bought a worse expected result. The distribution had not moved to the right; it had split into a thin sliver of enormous outcomes and a fat mass of dead accounts, and the sliver is not where you land.
Why the maths bends, not just the psychology
Two mechanisms, neither of them optional.
Volatility drag. Percentage gains and losses are not symmetric. A 10% loss requires an 11.1% gain to undo; a 50% loss requires 100%. As risk per trade rises, the swings get bigger, and the asymmetry compounds against you. Beyond the Kelly fraction — which for this system, once its 0.05R of costs is included, sits near 14.7% — adding risk lowers the long-run growth rate even in a world with no stop-trading rule at all. Two traders with the identical edge, one at optimal size and one at double optimal, do not both grow; the second one grinds toward zero.
Absorption. A drawdown limit is an absorbing barrier: once touched, the future is deleted. The account does not get to participate in the recovery its edge would have produced. And the probability of touching it does not rise gently with risk — look again at the second chart. Between 2% and 5% it goes from a rare event to a near-certainty.
The futures-specific version
Retail futures traders do not choose a risk percentage. They choose a number of contracts, and the leverage is whatever the contract specification says it is. That makes the trap concrete.
One ES contract at 5,000 index points is roughly $250,000 of exposure. On a $10,000 account that is 25 times leverage before you have made a single decision. A ten-point move — entirely ordinary, and available in the first fifteen minutes of a session — is $500, or 5% of the account. Two of those in a week and you are in the 10%-risk column above.
This is what micro contracts are actually for. MES is one tenth of ES; MNQ is one tenth of NQ. They are not training wheels, they are the only way most account sizes can express a 1% risk at all. Refusing to trade micros because they feel small is choosing the 10% column on purpose. Our position size calculator turns a stop distance into a contract count for the standard CME instruments, and will tell you plainly when the answer is “fewer contracts than one.”
The version of the argument that survives
There is a legitimate observation buried in the myth: a small account genuinely cannot compound to a living in a reasonable time, and pretending otherwise is its own dishonesty. Ten thousand dollars at a very good 30% a year is $3,000. That is the real problem, and leverage does not solve it — it converts a slow problem into a fast one.
The honest answers are unromantic. Add capital from outside the account. Trade a small account to build a verified track record rather than an income. Or accept that the account is a training instrument and size it to survive the training. What does not work, on these numbers, is asking leverage to make a small edge into a large income before the drawdown arrives.
Verdict
- Busted. With a −30% stop-trading rule, the median outcome peaked at 3% risk per trade and got steadily worse above it. At 10% risk the median account finished where it started.
- The blow-up threshold is a cliff, not a slope. Accounts touching a 30% drawdown went from 7.5% at 2% risk to 94.1% at 5% risk.
- Volatility drag is arithmetic, not sentiment. Past the optimal fraction, more risk lowers the long-run growth rate even with no drawdown limit at all.
- Futures leverage is a contract choice. One ES on a $10,000 account is 25x exposure before any decision. Micros exist so that 1% risk is expressible.
- Leverage cannot fix a small account. It converts a slow problem into a fast one, and the fast version has an absorbing barrier.
