Prop firm scaling plans: Apex, Topstep & MyFundedFutures
Scaling plans decide how big you can trade and when you're allowed to grow. They're where most funded traders get stuck — not on the eval, but on the contract caps that hold position size below the risk you're actually willing to take.

A scaling plan is a firm's rule for how many contracts you can hold at each phase of your account's life. It exists for two reasons: protect the firm from blowups and reward consistent traders with larger size. Each firm structures it differently — and that structure quietly shapes what strategies are viable.
What scaling plans usually gate
- Max contracts at start — often a fraction of the “full” account allowance until certain conditions are met.
- Phase triggers — profit milestones, number of payouts, or days traded that unlock larger size.
- Per-trade vs aggregate — some firms cap each ticket; others cap total open contracts across instruments.
- Consistency & news-trading rules on top, which can effectively lower your size in practice.
How the three big US futures firms differ in shape
Apex Trader Funding — scaling tied to account growth and payout history; multiple account tiers each have their own contract ceiling. Allows running several PA accounts in parallel.
Topstep — established model with strict consistency rules. Scaling is tighter at the start and opens up after the combine and initial funded period. Reputation skews toward discretionary day traders.
MyFundedFutures — newer, with more flexibility in account model choice (EOD trailing, intraday trailing or static drawdown). Scaling often more permissive on payout speed.
The numbers behind those structures change — firms tweak caps, payout thresholds and consistency rules regularly. Always confirm current rules directly with the firm before sizing a system around them.
What it means for a systematic strategy
If your modeled blow rate looks great at 3 contracts but your firm caps you at 1 until you stack three payouts, your real return path is slower than the backtest implies. Two practical adjustments:
- Model the scaling in: run the Pass Estimator at the contract size you'll actually trade, not the theoretical max.
- Pick the firm whose scaling shape fits your frequency — high-frequency systems suffer most from tight initial caps; lower-frequency, swing-style systems live more comfortably on Topstep's model.

FAQ
What is a prop firm scaling plan?
A rule that limits how many contracts you can trade at each phase of your funded account. Caps typically start low and increase as you hit profit milestones, payouts or days traded.
Which prop firm has the easiest scaling plan?
It depends on your strategy. MyFundedFutures tends to be more permissive on payout speed and offers multiple drawdown models. Apex allows running several accounts in parallel. Topstep is stricter early but well-established. Confirm current rules with each firm.
Do scaling plans matter for systematic strategies?
Yes. If your backtest assumes a contract size your scaling plan won't let you trade for months, your real-world return path is much slower than the model implies. Always size estimates around what you're actually allowed to trade.
