Scaling Plan: How Prop Firms Raise Your Position Limits
A scaling plan starts you small and raises your position limit as the account builds profit. Plan your first weeks around the smallest tier, since that's where you'll trade them.
Definition
Scaling plan A prop firm schedule that raises a trader's maximum position size, or the account size itself, as the account reaches set profit milestones.
Also called Scaling rule, Contract scaling, Account scaling.
Max position: 3 contracts. That’s the first thing many funded traders see on the dashboard, even on an account whose stated size would seem to allow far more, and it stays that way until the account has earned the next step.
A worked set of tiers
Here is a hypothetical three-tier plan for a futures account. Tiers differ by firm and by product, so treat these as an illustration.
| Account profit | Maximum contracts |
|---|---|
| Below $1,500 | 3 |
| $1,500 to below $3,000 | 6 |
| $3,000 and above | 10 |
Now put a stop on it. Suppose your usual stop costs $100 per contract.
At the first tier, you’d need five full-size winners of $300 each just to get to $1,500 and move up to tier two. The plan is designed to make that take a while.
Why firms use it
A new funded trader hasn’t shown consistency yet. Capping size early limits how much damage one bad week can do before the firm has seen how you trade, and it means the larger limits go only to accounts that have already built a profit cushion above the starting balance.
Some firms scale the account size itself. A trader who hits a milestone moves from one account size to a larger one, sometimes with a better profit split attached.
What it means for your sizing
Plan the early weeks at the smallest tier. It’s tempting to build a strategy around the size you’ll have later, then squeeze it into three contracts, but a stop and target that made sense at ten contracts may not produce enough per trade at three, and the temptation is to widen targets or trade more often to make up the gap.
Build the plan the other way round. Decide what a normal day looks like at three contracts, what a bad day costs at three, and how long reaching $1,500 takes if you stay at that size. Then treat each new tier as a change you adjust to deliberately.
Watch the step-down rule too. If a losing stretch drops the account below a threshold and the firm reduces your limit, you’ll be trying to recover at the smaller size, which takes longer than the loss did.
How it interacts with other rules
Scaling sits on top of the drawdown and daily loss limits. Hitting a new tier doesn’t widen them. So a trader who moves from 3 contracts to 10 can now lose more per trade against a floor that may not have moved much, and one full loss at the new size can eat a large share of the remaining room.
A consistency rule can bite at the same moment. If one big day pushes you into a new tier, it may also be the day that puts too large a share of your total gain into one session, a trap covered in consistency rules and your best day.
Evaluations versus funded accounts
Scaling plans turn up most often on funded accounts. Some firms also apply one during the evaluation, which slows the path to the profit target. Read both rule sets.
Product matters too. A firm may count a smaller contract differently from a full-size one toward the limit, or apply separate tiers to different markets, and the same dashboard can show a limit that means something different depending on what you trade.
Where you see it
Look for a field labeled max contracts, position limit or scaling tier on the account dashboard. Some platforms reject an order above the limit outright. Others accept it and flag a violation afterward, which is worse. Know which. A rejected order is an annoyance; a flagged violation can cost you the account.
What people get wrong
Assuming the stated account size is the size you can trade. On a funded account with a scaling plan it usually isn’t, not at the start.
The other mistake is chasing the next tier. Adding trades to reach $1,500 faster puts the account at risk for the sake of a bigger limit you haven’t learned to use yet. The rest of the prop rules are grouped on the prop trading desk.
Readers also ask
Do prop firms scale you back down after losses?
Some do. Under a plan with step-downs, falling below a profit threshold returns the account to the lower position limit until the profit is rebuilt. Other plans keep the higher limit once it has been reached. The rule page for your account should say which, usually next to the tier table.
Does a scaling plan apply during the evaluation?
It depends on the firm. Some apply the tiers only once an account is funded, while others also cap position size by tier during the evaluation, which slows progress toward the profit target. Read the evaluation and funded rule sets separately, since they can differ.
How should I size trades under a scaling plan?
Build around the smallest tier, since that's the size you'll trade first and possibly for weeks. Work out a normal day, a bad day and the time needed to reach the first milestone at that size, then adjust deliberately when a new tier opens. The drawdown limit doesn't grow with the tier.
