Topstep's “$50K account” does not mean you can lose $50,000. At the start of a $50K Trading Combine, the number that matters is a $2,000 Maximum Loss Limit. The initial failure line is therefore $48,000—and it can trail upward after profitable days.
There is another number traders often misread: the 55% Consistency Target. It is not a second fail-the-account rule. If one profitable day becomes too large a share of your total profit, Topstep raises the total profit you need to pass.
That distinction changes how the evaluation should be traded and journaled. You need to track two separate constraints:
- survival: the real-time distance between your account and the Maximum Loss Limit;
- consistency: your best profitable day divided by total profit.
This guide explains the current Trading Combine structure using Topstep's official rules checked on September 12, 2026. It covers the evaluation stage, not every payout rule that applies after funding.
Topstep Trading Combine rules at a glance
Topstep describes the Trading Combine as a simulated evaluation with one rule and two objectives.
- Rule: do not let the account balance hit or fall below the Maximum Loss Limit (MLL).
- Objective 1: reach and maintain the Profit Target.
- Objective 2: meet the 55% Consistency Target.
The official parameters currently allow a Combine to be passed in as few as two trading days. Topstep defines a trading day as 5:00 PM CT through 3:10 PM CT the following calendar day.
| Account | Profit target | Maximum loss | Initial MLL floor | Maximum position |
|---|---|---|---|---|
| $50K | $3,000 | $2,000 | $48,000 | 5 minis / 50 micros |
| $100K | $6,000 | $3,000 | $97,000 | 10 minis / 100 micros |
| $150K | $9,000 | $4,500 | $145,500 | 15 minis / 150 micros |

Maximum position size is a ceiling, not a recommendation. Topstep counts micros and minis at a 10:1 ratio in the Trading Combine. A $50K account can technically hold five minis, but using that capacity can consume a $2,000 loss allowance surprisingly quickly.
What the $50K account really lets you lose
The Maximum Loss Limit is the lowest permitted account balance. For a new $50K Combine:
Starting balance: $50,000
Maximum Loss Limit amount: $2,000
Initial MLL floor: $48,000
If balance or equity touches $48,000, the rule is broken. Topstep says both realized and unrealized P&L count in real time. A stop order placed exactly at the floor is therefore not a safety plan: slippage or a fast market can carry equity through the limit before the exit fills.
The MLL also trails. Topstep recalculates it from the end-of-day balance, it never moves down, and it stops trailing once it reaches the starting balance.
Consider this five-session path for a $50K Combine:
| After session | End balance | Next MLL floor | Room next session |
|---|---|---|---|
| Start | $50,000 | $48,000 | $2,000 |
| Day 1 | $50,500 | $48,500 | $2,000 |
| Day 2 | $50,000 | $48,500 | $1,500 |
| Day 3 | $51,400 | $49,400 | $2,000 |
| Day 4 | $52,200 | $50,000 | $2,200 |
| Day 5 | $51,250 | $50,000 | $1,250 |

Day 2 is the trap. The trader gave back the previous day's $500, but the loss floor stayed at $48,500. By Day 5 the MLL had already locked at $50,000, so the account had only $1,250 of room despite still displaying the “$50K” label.
This is why balance alone is an incomplete journal field. Record the current MLL floor and calculate the distance to it before every session:
Distance to MLL = current equity − current MLL floor
Then leave a buffer inside that distance. The platform line is the liquidation boundary, not a rational stop-loss level.
The 55% consistency formula
Topstep calculates the Trading Combine consistency percentage as:
Best single-day profit ÷ total profit
At the point of passing, the result must be 55% or less. The value is not rounded and Topstep says there is no hidden buffer.
The standard Profit Targets are $3,000, $6,000 and $9,000. Multiplying each by 55% produces the best-day levels that do not increase the target:

Suppose a $50K trader earns $2,200 on the best day and later reaches the original $3,000 target:
$2,200 ÷ $3,000 = 73.33%
The account has not failed, but it has not met the consistency objective. The new required total is:
$2,200 ÷ 0.55 = $4,000
At $4,000 total profit, that same $2,200 day represents exactly 55%. The trader needs another $1,000 on one or more later trading days without setting an even larger best day.
| Best day | Total profit | Best-day share | Total needed |
|---|---|---|---|
| $1,600 | $3,000 | 53.33% | $3,000 |
| $1,650 | $3,000 | 55.00% | $3,000 |
| $2,200 | $3,000 | 73.33% | $4,000 |
| $2,200 | $4,000 | 55.00% | $4,000 |
| $2,750 | $5,000 | 55.00% | $5,000 |

There is one more practical catch: profit added during the same session also enlarges that day's result. Topstep says a consistency excess cannot be repaired by trading more on the same day. The additional profit must come on a later trading day after the session in which the best day was set.
Consistency breach versus rule violation
The language matters because the outcomes are different.
- Touch the MLL: the Trading Combine becomes ineligible for funding until it is reset. This is the actual rule violation.
- Exceed 55% consistency: the account remains active, but the profit needed to pass increases. This is an unmet objective, not an MLL breach.
- Trigger an optional Daily Loss Limit: Topstep flattens positions, cancels pending orders and blocks new trades until the next session, but says the account remains eligible for funding.
The Daily Loss Limit is now optional for ordinary Trading Combines. If selected at checkout, Topstep currently lists $1,000 for a $50K account, $2,000 for $100K and $3,000 for $150K. TopstepX also provides personal risk settings, although manually adjustable limits are only as strong as the trader's willingness to leave them locked.
Do not mix those limits with the MLL. The optional daily limit is a session brake; the MLL is the evaluation's failure line.
A safer daily risk budget
The platform maximum is too large to use as the trading plan. Build a smaller internal budget from the tighter of three constraints:
- remaining room above the MLL after a buffer;
- your own daily loss cap;
- the amount of profit still available before your preferred best-day ceiling.
For example, imagine a $50K account with:
- current equity of $50,900;
- current MLL floor of $49,000;
- a $400 safety buffer;
- a personal daily stop of $500;
- $1,250 already earned today;
- an internal best-day ceiling of $1,500.
The MLL-based room is $50,900 − $49,000 − $400 = $1,500. The daily stop allows $500. The consistency headroom is $1,500 − $1,250 = $250. If the goal is to protect the planned consistency ceiling, $250 is the binding constraint—not the five-contract platform maximum.
Position size should then come from entry-to-stop risk. If one micro contract risks $35 at the intended stop, seven micros risk $245 before commissions and slippage. The Risk/Reward Calculator can make the entry, stop, target and dollar risk explicit before the order is placed. The position-sizing guide explains why the stop distance must drive size rather than the account label.
What to record in a Topstep journal
A normal trade log is not enough for an evaluation account. Add a rule dashboard to the daily review in your Trading Journal:
- account size and evaluation stage;
- start-of-session balance and equity;
- current Maximum Loss Limit floor;
- distance to MLL before the first trade;
- personal daily loss limit and whether it is locked;
- daily realized and unrealized P&L;
- largest profitable day to date;
- total profit and current consistency percentage;
- adjusted profit required, calculated as
best day ÷ 0.55when that exceeds the original target; - maximum planned contracts and actual peak contracts;
- planned risk, realized loss and slippage for each trade;
- rule-followed checkbox and a short explanation for any deviation.
Review the rule dashboard before reviewing setups. A profitable trade can still make the evaluation harder if it enlarges the best day beyond the planned ceiling. A valid setup can still be untradeable if its normal stop would put equity too close to the MLL.
If you are building the journal from scratch, use the field structure in how to keep a trading journal. If several copied or correlated trades can lose together, treat them as one risk event rather than several independent positions.
A five-minute pre-session checklist
Before placing the first order:
- Refresh the MLL floor. Use the platform value, not yesterday's memory.
- Calculate distance to MLL. Subtract a safety buffer for slippage and fast markets.
- Update the best day and total profit. Recalculate consistency rather than estimating it.
- Set a daily stop and daily profit ceiling. On TopstepX, decide whether to lock the relevant personal risk settings.
- Convert dollar risk into contracts. Use the actual stop distance for the instrument being traded.
- Check the active account. Topstep explicitly warns traders with multiple Combines to confirm the selected account.
- Define the stop-trading condition. Write it before P&L can influence the decision.
After the session, lock the final daily P&L into the journal. Topstep says the best-day result becomes final at 3:10 PM CT. Then record the next MLL floor and the new required total profit.
Topstep versus FTMO: do not reuse the same worksheet
The risk logic is different. Topstep's Trading Combine uses an end-of-day trailing Maximum Loss Limit plus a 55% consistency objective. FTMO evaluations use their own daily and maximum loss calculations, with different reset and equity mechanics. A journal template built for one firm can therefore show the wrong remaining risk for the other.
If you compare futures evaluations with CFD-style challenges, read the FTMO Challenge rules breakdown separately and keep a rule profile for each account. The lesson is broader than either brand: “account size” is marketing shorthand; the loss formula determines the real risk budget.
Frequently asked questions
What is the main rule in the Topstep Trading Combine?
Do not let the account balance or equity hit or fall below the Maximum Loss Limit. Topstep monitors realized and unrealized P&L in real time.
What is the loss limit on a Topstep $50K Trading Combine?
The published Maximum Loss Limit is $2,000, so the initial floor is $48,000. The floor trails upward with profitable end-of-day balances and locks at $50,000 once it reaches the starting balance.
Is Topstep consistency 50% or 55%?
Topstep's current Trading Combine help pages state 55%. The company says the former hidden buffer is gone and 55% is now the hard displayed line. Because rules can change, check the official parameter page before trading.
What happens if my best day is more than 55%?
The Combine does not fail solely for that reason. Your required total profit increases to best-day profit divided by 0.55. Profit earned later can reduce the percentage, provided a later session does not create a still larger best day.
Can I pass a Topstep Trading Combine in one day?
No. Topstep currently says a trader can pass in as few as two days while meeting the Profit Target and 55% Consistency Target.
Does hitting a Daily Loss Limit fail the account?
Topstep says its optional Trading Combine DLL is a forced break, not a rule violation. Positions are flattened and trading is blocked until the next session, while the account remains eligible for funding. The Maximum Loss Limit is different.
Does the Maximum Loss Limit include open losses?
Yes. Topstep states that unrealized P&L counts in real time. A final filled balance above the MLL does not reverse a breach that occurred while a position was open.
Sources and calculation method
Current rules were checked September 12, 2026 against Topstep's official Trading Combine Parameters, Maximum Loss Limit, Consistency at Topstep and Daily Loss Limit pages.
The tables use the published account parameters. Consistency examples calculate best day ÷ total profit; adjusted required profit is the larger of the original target and best day ÷ 0.55. The MLL example applies Topstep's published end-of-day trailing method and caps the floor at the starting balance. Arithmetic is reproduced in drafts/topstep-trading-combine-rules-numbers.mjs.
