Topstep Trading Combine Rules, Strategy, and Common Mistakes

A futures evaluation like the Topstep Trading Combine is a rules test as much as a trading test. A strategy that makes money can still fail the evaluation if it breaches a daily loss limit, mis-tracks a trailing drawdown, or ignores a time restriction. This article does not list current account sizes, prices, profit splits or limits, because those change. It shows how to read the rules, run the arithmetic on a hypothetical rule set, and avoid the common errors. For current terms, use the firm's current rules.

What to Read Before You Pay

Open the rule document and answer these questions in writing:

• Profit target, and whether there is a minimum number of trading days.
• Daily loss limit: is it a hard fail or a pause for the day, and does it include open profit and loss?
• Max drawdown: is it trailing, how is it measured (on closed balance, end of day, or intraday including open positions), and does it stop trailing once it reaches the starting balance?
• Position limits, scaling rules, and which contracts are allowed.
• Rules on holding positions past the daily close, and the cutoff time in a stated timezone.
• Any consistency rule and which stage it applies to.
• Fees, including monthly charges, reset fees and activation fees, plus payout terms. For automation, the TopstepX API policy permits SIM access from a personal device, excludes Live accounts and prohibits VPS, VPN or remote-server order transmission. That does not establish compatibility for a NinjaTrader bot.

Firms differ, and the same firm can differ by product and account vintage. A funded account is not live trading, and an evaluation fee does not cap every downside, since fees repeat on a reset. Nothing here guarantees a pass or a payout.

Hypothetical Rule Set for the Math

Suppose the rules read: $50,000 start, $3,000 profit target, $1,000 daily loss limit, $2,000 trailing drawdown, 10 minimum trading days. These are made up for the arithmetic and are not the current terms of any firm.

Tracking a trailing drawdown

The floor starts at $48,000 ($50,000 minus $2,000). If the account peaks at $52,000, a trailing floor rises to $50,000. A drop to $49,500 then breaches it, even though the account is still above the $50,000 start. Whether the peak counts open profit or only closed balance is in the rules, and that detail changes your risk, so confirm it.

Keep a simple sheet: date, opening balance, daily result, account value, floor, and buffer (account value minus floor). When the buffer is smaller than one daily loss limit, size down. When it is wide, you can trade normal size.

Here is how a floor creeps up. You make $1,500 in week one, so the peak is $51,500 and the floor is $49,500. You lose $1,200 in week two, so the account is $50,300 and the buffer is only $800, less than the $1,000 daily limit. You are still profitable versus the start, but one normal bad day could end the attempt.

Daily target arithmetic

$3,000 over 10 days averages $300 a day. On ES, $300 is 24 ticks ($12.50 x 24), or 6 points, before commissions and slippage. On MES the same $300 is 240 ticks of contract value, which is why contract count has to be chosen deliberately. Picking an average per day helps with pacing, but it is not a promise the market will deliver it. Some days will not offer a setup, and forcing one is how evaluations end.

A Process That Protects the Account

1. Use the size you normally trade. The usual way evaluations fail is a trader doubling or tripling size to hit the target faster and then hitting the daily limit on the first adverse day.
2. Set a personal daily stop at a fraction of the firm's limit, for example half. On the hypothetical $1,000 limit that is $500. When it triggers, stop for the day.
3. Use any mechanical safeguard your platform or broker offers as a backup, and test it in simulation so you know it actually fires. Don't rely on a setting you have never tested.
4. Define a daily target and a stop-for-the-day rule. After the target, additional trades add risk for little purpose.
5. Spread activity over the minimum day count on purpose. If the target is hit early, you may still be required to trade more days, so read how the rule counts a day.
6. Calendar your session cutoff in the firm's timezone, and set an alarm before the cutoff if overnight holds are restricted.

Common Failure Modes

Oversizing early. A bigger-than-normal position leaves less room for an ordinary losing trade.

Revenge trading. Down 40 percent of the daily limit by mid-morning, a trader adds size to recover and breaches the limit. The personal stop exists for this moment.

Ignoring drawdown creep. The floor only moves up, so a profitable stretch shrinks your cushion without feeling like it.

Missing a close-out. Forgetting to flatten before the cutoff can break a no-overnight rule. Remember that NinjaTrader and your broker's clocks may not match the firm's, so verify.

Treating the evaluation as a different game. Changing strategy for the evaluation means you are testing something you have not practiced. Practice the same plan in simulation first, and keep in mind that a simulated fill is not the same as an exchange fill with real queue position and slippage.
