Two strong futures prop firms with very different DNA. Topstep enforces a daily loss limit and locks drawdown at your starting balance. MFFU has no DLL on any plan and gives you a $100 lock cushion. Here's the rules, the math, and who each one actually fits — no affiliate spin.
| Topstep | MyFundedFutures | |
|---|---|---|
| Account sizes | 50K, 100K, 150K | 50K (Core only), 50K/100K/150K (Rapid), 50K/100K/150K (Pro) |
| Evaluation structure | Combine (eval) → Express Funded Account (XFA) | Core (eval) / Rapid (eval) / Pro (instant funding, no eval) |
| Trail type (eval) | Intraday (Combine) | EOD (Core), Intraday (Rapid) |
| Trail type (funded) | EOD (XFA) | Same as your eval plan (Pro = EOD) |
| Trail locks at | Starting Balance ($0 net P&L) | Starting Balance + $100 |
| Daily Loss Limit | Yes — $1,000 / $2,000 / $3,000 | None on any plan |
| Profit target (50K) | $3,000 | $3,000 (Core or Rapid) |
| Profit target (100K) | $6,000 | $6,000 (Rapid) |
| Profit target (150K) | $9,000 | $9,000 (Rapid) |
| Consistency rule | 50% of total (eval) | 40% (Core, eval + funded), none (Rapid) |
| Profit split | 80–90% scaling | 80–90% |
| Payout cadence | Monthly minimums w/ scaling rules | Every 5 days (48h after first) |
| Activation fee | None | None |
| Brand age | Founded 2012 (oldest major futures prop) | Newer firm, post-2020 |
Both firms use a trailing drawdown, but the trigger and the lock point differ.
The drawdown floor follows your equity high-water mark up but never down. As your account makes new highs, the "you fail here" line rises with it. Below the floor = blown account.
Imagine a 100K account at both firms. You build to $105,000 then drift back. Once your trail catches up:
It's only $100 of cushion. But it matters psychologically: with MFFU you can be slightly net-negative on the day and the account survives. With Topstep, your account dies at break-even.
This is the headline difference. Topstep enforces a daily loss limit. MFFU does not.
| Size | Topstep DLL | MFFU DLL (any plan) |
|---|---|---|
| 50K | $1,000 | None |
| 100K | $2,000 | None |
| 150K | $3,000 | None |
It's a hard floor enforced by the platform. Hit it and your account is locked for the session. It's calculated on a "max daily loss" mechanic that's the larger of: (a) the dollar limit, or (b) your trailing drawdown remaining. In practice the dollar limit is the binding constraint early on. The DLL is non-negotiable — you can't disable it.
Your only failure condition is the trailing drawdown. You could theoretically lose $4,000 on a 50K Rapid in a single session (which would blow you anyway since the DD is $2,000) — but you'd have to do it in one move. There's no session-level sub-cap. This means:
Size it first → Position-size calculator — on MFFU without a DLL, the trail is the only floor. Model contracts against stop distance and per-trade risk % so the "more rope" doesn't become the rope you hang yourself with.
Deep dive → Daily loss limit explained (2026) — Topstep and MFFU are both DLL-absence stories for many traders today, but via STRUCTURALLY different mechanisms. MFFU never adopted a DLL on any plan (Core, Rapid, Pro). Topstep is platform-toggled: TopstepX removed the default DLL in August 2024, while NinjaTrader users still get one. Same lived experience, opposite stability profile: MFFU's absence is a design choice, Topstep's TopstepX-only absence is a recent platform decision that could reverse. The post's 4-archetype taxonomy — platform-toggled (Topstep), firmwide-absent (MFFU + TPT), fork-locked at signup (Apex 4.0 + Bulenox), per-program-configured (Tradeify) — is the durable lens for which firms' DLL policy you can trust to stay put.
Both firms use consistency rules to prevent "passing the eval on one lucky day." But the thresholds and scope differ.
| Firm | Threshold | Scope |
|---|---|---|
| Topstep | 50% of total | Evaluation (Combine) |
| MFFU Core | 40% of total | Evaluation AND funded payouts |
| MFFU Rapid | None | — |
| MFFU Pro | Plan-specific | Confirm with rulebook |
Best-day-must-be-≤-threshold-of-total translates to a hard formula. Given total P&L T and threshold t:
t × T — so on Topstep no day can exceed 50% of total; on MFFU Core no day can exceed 40%.B / t − TYou're at $2,400 total profit on a Combine. Best day = $1,400. Ratio = 58.3% — over the 50% line. You need additional profit before you can pass: (1,400 ÷ 0.5) − 2,400 = $400. You can't have any day exceed $1,400 either.
You're at $2,400 total profit on a Core 50K. Best day = $1,400. Ratio = 58.3% — over the 40% line. Additional profit needed: (1,400 ÷ 0.4) − 2,400 = $1,100. The lower threshold is stricter — one big day eats more future profit-runway.
Deep dive → Consistency-rule explained (2026) — the 50% vs 40% headline is the threshold axis, but the load-bearing wedge between Topstep and MFFU Core is the SCOPE axis: Topstep's 50% binds eval-only (passes the Combine, free forever on the XFA), while MFFU Core's 40% binds eval AND every funded payout. The full cluster sits on a threshold × scope grid: Apex 4.0 30% funded-only, Earn2Trade GAU 30% eval-only, MFFU Core 40% both-scope, Tradeify Growth 35% both-scope, Topstep 50% eval-only. "Permissive 50% vs strict 40%" flips entirely once scope enters — eval-only-50% on Topstep may be looser than both-scope-40% on MFFU Core during the eval, but vanishes as a binding constraint the moment you're funded.
| Feature | Topstep | MyFundedFutures |
|---|---|---|
| Cadence | Monthly minimum thresholds, scaling rules apply | Every 5 days (48h after first) |
| Split | 80–90% with scaling | 80–90% with scaling |
| Minimum payout | Per Topstep scaling plan | Per MFFU current rulebook |
| Consistency check at payout | Eval-stage only | Core: at every payout. Rapid: no consistency check. |
MFFU's faster cadence is real cash-flow value. Topstep's monthly rhythm forces more capital to sit. But Topstep's funded account model removes intraday trail pressure on the XFA, which has its own kind of value.
You take ES short, go $800 against you intraday, then ride it back to +$300 close.
You earn $3,500 total on a 50K. Best day = $1,800.
(1,800 / 0.5) − 3,500 = $100 more profit before passing. Tiny fix.(1,800 / 0.4) − 3,500 = $1,000 more profit before the payout is consistent. Much bigger fix — and remember the rule applies at every funded payout, not just the eval.You're up $1,500 for the week on a 50K. Monday: stop hunt at the open, you take three losers, −$1,200 by 9:45am.
Model both Topstep and MFFU presets. Compare intraday vs EOD trail, see how the lock point ($SB vs $SB+100) plays out across simulated weeks.

Open calculator →Different "easier." Topstep Combine has a 50% consistency rule (more permissive) but enforces a DLL, so one bad morning can lock you out for the session. MFFU Core has a stricter 40% consistency rule (applied to eval AND funded) but no DLL. If you take steady measured profits with no one big day, MFFU Core's consistency rule is harder. If you're prone to one breakout-day skews, Topstep's 50% is easier.
You can, and your account will die when it hits the trailing drawdown. The DLL absence doesn't expand your max loss — the trail still caps you. It just removes the session-level sub-cap. The "rope" is the same total; it's just whether you can use it all in a day or are forced to spread it.
Topstep's XFA structure is genuinely nice — you grind through the intraday Combine, then once funded you switch to a lower-pressure EOD trail. MFFU's Core (EOD) gives you EOD throughout, but with the trade-off of stricter consistency. If you want EOD on the funded account specifically, both work; Topstep just gets there through a different on-ramp.
Cash flow timing. If you're treating prop as a real income stream, getting paid every 5 days versus once a month means lower latency between work and reward, which is also a behavioral edge — profits feel more real, fewer to "give back." Topstep's monthly cadence is more capital-intensive but forces longer-cycle thinking, which some traders prefer.
In dollar terms, it's small. In behavioral terms it's notable: you can finish a session a few ticks net-negative without blowing the account. With Topstep XFA, your account dies exactly at $0 net P&L — one bad close and it's over. It's not a reason to pick MFFU on its own, but it adds a small margin of error.
Yes, and many traders do — it's diversification across rule sets. Just be aware of position-correlation if you're trading the same instruments at both firms. A bad ES day hits two accounts at once. A good journal (e.g. Aurafy) lets you tag accounts by firm so you can see real per-firm performance.
The lowest-fee starting points are Topstep 50K Combine or MFFU 50K Core/Rapid. Both let you learn prop-firm dynamics on a small drawdown ($2,000 or $1,500). Pick by personality: Topstep if you want forced session-level discipline, MFFU Rapid if you want total flexibility, MFFU Core if you want EOD trail + are comfortable with the 40% consistency rule.
Tag each trade with the firm + account, and Aurafy will alert you when you're approaching your trailing drawdown or about to break consistency on your next payout. Built specifically for prop-firm futures traders.
