Position size

Size up slowly. Size down instantly.

When to trade more contracts on a prop firm account: a three-step ladder, the criteria to climb, the drawdown test, and the three signals that take you back down.

The size ladder

Step 1 · 1 microWhere every account and every month starts.
Step 2 · 2 micros10 sessions in a row at step 1 without a major slip, an average process score of 4 or more, and your new daily stop still well below the firm’s daily limit and far from your drawdown.
Step 3 · 3 microsThe same criteria, 10 sessions at step 2. Step 3 is the ceiling for Month 3.

Every account, and every new month, starts at step 1.

The drawdown test

Before each step up, check that your distance to the max loss still holds at least 2 full days of your daily stop at the new size. Example: with $1,200 left before the max loss and a daily stop of $100 at 1 micro, you can absorb 12 bad days. At 3 micros, the daily stop is $300: 4 days, still above 2. With $500 left, 3 micros means less than 2 days: stay at your step, or step down.

Step down immediately if

  • You have 2 major slips within 5 sessions.
  • You hit your daily stop 2 sessions in a row.
  • Your distance to the drawdown no longer fits 2 full days of your daily stop at this size.

Stepping down is not a punishment. It’s the ladder doing its job: you climb back with the same criteria.

After a pass, a payout or a new account

Back to step 1 for 5 sessions. A win changes your account, not your process.

Micros before minis

One mini (ES, NQ) is worth 10 micros. Climbing from 1 to 3 micros keeps each step small; moving to a mini multiplies the risk by 10 at once. Your firm also caps the number of contracts per account: it’s on each firm’s page.

Practice the next step first

On 10 replay setups, calculate the risk at the next step. If the stop no longer fits your daily stop, the size has to wait, not your limits. The position size calculator does the math.

Always check your prop firm’s official rules for your account.

Questions

How many contracts should I trade on a 50K prop account?

Start with 1 micro, whatever the account size, and let the ladder add the next ones: 10 clean sessions per step, and always 2 full days of daily stop left before the max loss. The account size sets the firm’s limit, not your risk.

Should I size up after a big win?

No. After a pass, a payout or your best day, the next session is a normal one, at the same size. A win changes your account, not your process.

When should I size down?

Right away after 2 major slips in 5 sessions, 2 daily stops in a row, or when your distance to the max loss no longer holds 2 full days of daily stop.

Your edge, finally in one place.
