Prop firm scaling plans: how your contract limit grows

Many funded accounts start with a small contract limit that grows as the balance grows. Here's how a scaling plan works, and why the limit is a ceiling, not a target.

What a scaling plan is

A scaling plan is a rule that ties how many contracts you can trade to how much your account has grown.

Start small. Grow the balance. Unlock more size. Fall back below a level, and the limit may drop back too.

Firms use it so a new funded trader can't put on the biggest size on day 1, when there's the least room above the floor. For where it sits among the other rules, see prop firm rules explained. The numbers below are made-up examples, not any real firm's terms.

A sample scaling table

A $50,000 funded account, with a max drawdown of $2,000:

Some firms check this at the end of each day. Others check it live. Some count micro contracts as one-tenth of a full contract. Others count each one as one. Read the exact wording.

Why it exists: room versus size

Look at the start. Your room above the floor is $2,000.

Say you trade ES (E-mini S&P 500), where 1 point = $50, with a 6-point stop. One stop on one contract costs $300.

At 5 contracts, one normal losing trade uses three-quarters of the room. Two in a row ends the account. That's why the plan holds you at 2 contracts until you've built a cushion. That's a math example, not a promise.

Work out the dollar value of any stop with the futures tick value calculator.

Micros make scaling smoother

Micro contracts are one-tenth the size of their full versions. For the S&P 500:

• ES: 0.25 points = $12.50, so 1 point = $50
• MES: 0.25 points = $1.25, so 1 point = $5

With micros, you can grow size in small steps, like 3 MES, then 4, then 5, rather than jumping from 1 ES to 2. Our comparison micro vs E-mini futures covers the trade-offs.

What happens after a loss

If your balance falls back below a tier, your limit usually falls with it.

Trading above your current limit, even for a minute, can count as a rule break. Check the limit every morning, not just once.

The max is a ceiling, not a target

Being allowed 5 contracts doesn't mean 5 is a good size. The room above your floor still decides what's safe.

A simple way to size, whatever the plan allows:

1. Work out today's room: balance minus the floor.
2. Pick a small share of it for one trade. Many traders use a fixed amount, like 1% of the account or a set share of the room. See how much to risk per trade.
3. Divide that by the dollar cost of your stop on one contract.
4. Round down. Then take the smaller of that number and the scaling limit.

Example: room $2,600, risk per trade $260, stop costs $30 per MES. $260 ÷ $30 = 8.7 → 8 MES. The plan allows 30 micros at this tier, but your sizing says 8. Trade 8.

Scaling and the drawdown interact

As your balance rises, an end-of-day or intraday trailing floor may rise too. So more contracts don't always come with more room. See trailing drawdown explained.

If the floor has stopped trailing, room grows with the balance. If it hasn't, room may stay the same even as the limit rises. Always size from room, not from the limit.

Scaling and payouts interact too

A payout lowers your balance. That can drop you below a tier and shrink your limit. More in prop firm payouts explained.

Before you request a payout, check which tier you'll land in after it.

Common mistakes

• Jumping to the max the moment it unlocks. One bad trade at new size can undo weeks of growth.
• Forgetting the limit dropped. A losing day can lower it. Check before the first trade.
• Counting micros wrong. Some firms use 10 to 1, others 1 to 1.
• Sizing from the limit, not the stop. The chart sets the stop. The stop and your risk set the size.

Try it today

1. Pick one firm's public scaling table. Don't pay anything.
2. Write down your usual stop in points, and its dollar cost on one micro.
3. For each tier, work out your size using the 4 steps above.
4. Compare it with the tier's max. How often would you use the full limit?
5. Write one rule: "I add size only when ___." Keep it in your plan.
