The amount a broker will let you deposit and the amount you can trade responsibly are two different numbers. Brokers set margin, and margin is collateral, not a cap on what you can lose. The better question is how much account you need so that a normal losing streak does not end the experiment, and the answer comes from risk per trade and contract size.
Start with dollar risk, not margin
Pick the percentage of the account you will risk per trade. A common guideline is 1% to 2%. Convert it to dollars, then convert your stop distance to dollars using the contract's point value:
- ES: $50 per point, $12.50 per 0.25 tick
- MES: $5 per point, $1.25 per tick
- NQ: $20 per point, $5 per tick
- MNQ: $2 per point, $0.50 per tick
Contracts you can trade = (account x risk percent) divided by (stop points x dollar per point + estimated costs and slippage). Here are hypothetical stops, before costs:
| Setup | Dollar risk per contract | Account where that is 1% | Account where that is 2% |
|---|---|---|---|
| ES, 4-point stop | $200 | $20,000 | $10,000 |
| MES, 4-point stop | $20 | $2,000 | $1,000 |
| NQ, 10-point stop | $200 | $20,000 | $10,000 |
| MNQ, 10-point stop | $20 | $2,000 | $1,000 |
This is why micro contracts matter for smaller accounts. They let you size a trade to a dollar risk that a $2,000 to $5,000 account can carry. Add commissions and slippage to the risk number, and remember that a stop order can fill beyond its price in a fast market.
What margin does and does not tell you

Margin has two layers. The exchange sets a requirement, and your broker adds its own, which can be lower for intraday positions closed before the session ends. These numbers change with volatility and differ by broker, so look up the current figures on the CME's margin page and your broker's schedule rather than relying on any number in an article. A very low intraday margin means you can open a position, not that the position is sensible for your account. You can lose more than the margin posted.
A side note for anyone coming from stocks: FINRA replaced the pattern day trader rule with intraday margin rules effective June 4, 2026, with brokers allowed to transition through October 20, 2027, so some brokers may still apply the old $25,000 requirement during the transition. See the Investor.gov PDT explainer. That rule is for securities accounts. Futures accounts run on exchange and broker margin instead.
Account size scenarios
Under about $1,000
A 1-point MES stop is $5, which is 0.5% to 1% of the account before costs, and you have almost no room for a string of losses. This is better spent on simulation and learning the platform.
About $2,000 to $5,000
Workable with micros only. At 1% risk on $5,000 you have $50 of risk per trade, which is two MES contracts with a 4-point stop ($40) before costs. Focus on execution records and drawdown control rather than income.
About $10,000 to $25,000
Full-size ES or NQ becomes possible with a 1 to 2 contract size and stops in the 4 to 10 point range, but you can also stay in micros to scale in smaller steps. Check that your stop distance actually fits your risk percent before choosing the contract.
Above $25,000
More room for multiple contracts and scaling. The same discipline applies: size from the stop, not from the margin.
What undercapitalization does to you
- Stops get squeezed too tight to survive normal noise, or loosened until the loss is too large.
- A losing streak at high risk percent compounds quickly: five losses at 5% each leaves about 77% of the account (0.95 to the fifth power), while five losses at 1% leaves about 95%.
- When $200 is 10% of the account, every trade carries pressure that distorts decisions.
Comparing a prop firm evaluation
An evaluation changes the constraints, it does not remove risk. Do not rely on any fee or payout figure from an article, because rules differ by firm, product and account vintage. Pull the current rule documents and compare these items in writing:
- The evaluation fee, plus reset fees, monthly fees and data fees.
- Drawdown type (trailing or end of day) and daily loss limit.
- Profit target, consistency rules, minimum trading days and contract limits.
- Payout terms, split, and whether there is a waiting period.
- Rules on automation and which instruments are allowed.
A funded account is not the same as live trading in your own account, a payout is not guaranteed, and an evaluation fee does not cap every cost, since resets and subscriptions add up. A firm that offers exchange-traded ES and NQ is not interchangeable with one built on a different product, so check the instrument rules too. Model the total expected cost across several attempts before you compare it to a small personal account.
