Passing the Topstep Combine: MLL and Consistency, Explained Like

The two rules that eliminate most Topstep Combine attempts aren't the profit target — they're the Maximum Loss Limit and the consistency rule. Understand the mechanics of both and you can structure every trading day so neither one ever gets close.

How the Trailing MLL Actually Works

Topstep uses an end-of-day trailing drawdown, not an intraday one. That distinction matters more than most traders realize.

On the 100K Combine, your Maximum Loss Limit starts at $3,000. That means your account can fall to $97,000 before you're out. As your end-of-day balance rises, the MLL floor rises with it — but it trails from your highest closing balance, not your intraday peak. If you run a position to +$2,000 intraday and then give it all back before the close, the MLL floor doesn't move. Only the balance at end of day counts.

The second mechanic is the lock. The MLL stops trailing once your account closes at or above the starting balance — on the 100K that's $100,000, on the 50K it's $50,000, on the 150K it's $150,000. Once you close a day at breakeven or better for the first time, the floor locks permanently at the starting value. After that point the MLL behaves like a static drawdown: $3,000 of room on the 100K, $2,000 on the 50K, $4,500 on the 150K.

The practical consequence: early in the Combine, every profitable end-of-day actually tightens your cushion if you haven't yet locked the floor. Close Monday up $1,500 on the 100K and your MLL floor moves from $97,000 to $98,500. You now have only $1,500 of room instead of $3,000. A single bad Tuesday can end the evaluation before you've done anything reckless.

The Daily Loss Limit Is a Forced Stop, Not a Guideline

Separate from the MLL, Topstep imposes a hard daily loss limit. On the 100K Combine it's $2,000. On the 50K it's $1,000. On the 150K it's $3,000.

Hit that number intraday and you're done for the session — positions are closed and you cannot re-enter. This isn't a warning; it's a cutoff. The Topstep Daily Loss Limit covers the exact trigger mechanics, but the trading implication is simple: your per-session risk cap must sit comfortably below the daily loss limit, not equal to it. If your stop-loss plan risks $1,800 on a 100K account and the market moves fast, you can breach $2,000 on slippage alone.

A practical rule: keep your planned daily max loss at no more than 60–70% of the limit. On the 100K that means capping yourself at roughly $1,200–$1,400 per day. It feels conservative until you remember that one limit-down open or a spread blowout can eat several hundred dollars in seconds.

The 50% Consistency Rule Is the Silent Killer

This is the rule traders discover too late. On the Topstep 100K Combine, no single day's profit can exceed 50% of your total profit at the time you want to pass. The same 50% cap applies on the 50K and 150K Combines.

Here's how it bites you. Say you need $6,000 to pass the 100K Combine. You have a great Monday and make $4,000. You grind out another $2,000 over the next several days to hit $6,000 total. You're stopped out: Monday's $4,000 is 66% of $6,000. You cannot pass until you either make enough additional profit that Monday's day drops below 50%, or you accept that Monday's number is now a ceiling everyone else has to catch up to.

The math you need to keep in your head: your best single day must be less than half your total closed profit at submission. If your best day is $X, your total profit must be greater than $2X before you can pass.

The consistency rule applies to the funded account too, where it drops slightly to 40% — meaning you have a little more flexibility once you're earning real payouts, but it never disappears entirely. For the full breakdown of how consistency is calculated, Topstep's Consistency Rule, Explained walks through the edge cases.

For comparison, Apex Trader Funding's consistency rule uses a similar 50% cap but applies it differently — worth reading if you're evaluating which platform fits your style.

Sizing So Neither Line Gets Touched

The goal is to make both limits irrelevant to your normal trading. Here's the framework:

Set your position size so a normal losing day costs less than half the daily loss limit. On the 100K Combine, that's under $1,000 on a bad day. If your strategy loses an average of 3 ticks per contract on losing days, work backwards from that to a contract count.

Protect the MLL floor during the early phase. Before you've locked the floor at breakeven, every profitable close raises the floor and tightens your cushion. This sounds backwards, but it means: don't push size aggressively on early winning days just because you're in profit. A $500 average winning day that locks the floor after day three gives you more room than a $2,000 blowout day that leaves you with $1,000 of MLL cushion and nowhere to maneuver.

Target consistency-friendly profit distribution. You want no single day to dominate the P&L curve. Aim for roughly even daily contributions. If you have a runaway day early — say $3,000 on the 100K — immediately throttle back. You now need $6,000 total profit before that day falls below 50%, which means $3,000 more at the same consistency before you can even submit.

Track both limits in real time. The MLL floor can move against you overnight if you close up and haven't yet locked. The daily loss limit resets each session. Keeping a live number on remaining daily room and current MLL floor eliminates the surprise breaches that end most Combines.

PropGuard tracks both the trailing MLL floor and your daily loss consumption live, and alerts you before either limit gets within range — the kind of guardrail that removes the mental overhead during live trading.

The Minimum Days Rule Is the Easy One

Topstep requires a minimum of 2 trading days on both the Combine and the funded account. Two days is not a meaningful constraint for most traders — mention it only because traders occasionally try to pass in a single massive session and are surprised to find it blocked.

Putting It Together

The Topstep Combine has three independent trip wires: the trailing MLL, the daily loss limit, and the consistency cap. Each one can end your pass attempt independently of the others. Most failures come from ignoring one while managing another — usually from nailing the profit target on the back of one large day that violates the 50% rule.

Size for a normal losing day that never touches the daily loss limit. Keep early winning days measured to avoid collapsing the MLL cushion before the floor locks. Spread profit across sessions so no single day exceeds half your running total. All three rules become manageable when position size is set correctly from day one.
