How to Approach a Topstep Combine: The Futures Rules Forex Traders Miss

Key takeaways

  • A Topstep Combine is a futures evaluation, so the units, the day boundary and the drawdown mechanics differ from a forex challenge even when the dashboard looks the same.
  • Size is discrete in futures. You choose contracts first, and the tick value then decides how wide a stop your risk budget can pay for.
  • Where the evaluation uses a trailing drawdown, plan around it before the profit target. Your budget is the distance to the current threshold, not the balance on the screen.
  • Rule numbers change constantly. Use the categories in this article, then take the current figures from Topstep's own rulebook before your first trade.
  • Automation only helps if it knows the live threshold, stops itself before the limit, and gets updated when the firm changes a rule.

A Combine is a futures evaluation, not a forex challenge with new tickers

Arriving at Topstep from forex, the first screen looks reassuringly familiar. A profit target, a loss limit, a dashboard counting your progress toward funding. That surface similarity is what costs people the account in the first few sessions, because almost everything underneath it works differently.

Futures are exchange traded contracts. Size, tick increment and the dollar value of each tick are fixed by the exchange and identical for everyone in the book. There is no broker choosing your lot granularity, no fractional position, no volume slider to shade a position when a setup feels marginal. You are in one contract or you are not.

The evaluation sits on top of that structure and inherits its hard edges. The rule categories look familiar, a target, a daily limit, a drawdown, but the units, the day boundary and the drawdown mechanics differ enough that a forex plan can fail for reasons unrelated to your edge.

One warning before anything else. Every specific figure in a futures evaluation, the target, the limits, the contract caps, the cutoff times, is set by the firm and gets revised, and tiers and product names get renamed too. Nothing here quotes Topstep's current rules or assumes which tier you bought. Read this as a map of the categories, then trade from the rulebook on the firm's own site.

Contracts are not lots, and that breaks your sizing math first

In forex you tune risk by adjusting volume. Pick the stop, solve for lot size, and almost any risk figure is reachable. Futures has no such dial. The smallest unit is one contract with a fixed dollar value per tick. Micro contracts are what make a modest evaluation account tradable at all, but even a micro is a step, not a slider.

So the order of the math inverts. You choose the product, which fixes the dollars per tick. You choose the number of contracts, a whole number. Only then do you learn how many ticks of stop your risk budget can pay for, and whether that stop survives the instrument's normal noise. When it does not, the trade does not exist at that account size today.

Illustrative arithmetic only, with invented figures. It is not a Topstep rule and not a quote of any contract's specification. If a product were worth five dollars per tick and your plan allowed 150 dollars of risk on one contract, your stop could be thirty ticks wide. On a product with four times the tick value, the same budget buys a quarter of that distance. Take real tick values from the exchange contract specifications and the contract cap from the firm's current rulebook.

This is also where the forex reflex of scaling in does damage. A second contract does not add a little risk, it doubles the dollars per tick across the whole position, and on a fast index product that lands inside one candle.

The rule categories in a futures evaluation, and what to look up yourself

Read any futures evaluation as a set of categories, not a set of numbers. The categories are stable. The numbers are not. The same families of rules show up at other futures firms, see the Apex rules every bot must respect.

  • Profit target: what you must reach to complete the evaluation. Treat it as a distance covered slowly, never as a weekly quota.
  • Daily loss limit: how much you can lose in one trading day before the account is stopped. In futures this is often enforced by the platform in real time rather than reviewed after the fact.
  • Drawdown: whether the disqualification level is anchored to your starting balance or trails your equity, and if it trails, on what basis. This is the subject of the next section.
  • Minimum trading days: where a firm sets one, a floor on how many separate days you must trade, so one strong session cannot qualify you alone.
  • Maximum position size: a cap on contracts held at once, sometimes tiered by account size or by how close you are to the target.
  • Session and flat by times: whether positions may be held through the daily close, through the maintenance break, or overnight at all.
  • Consistency requirements: whether one outsized day can disqualify a result or delay a payout, which usually bites at payout time rather than during the evaluation.
  • Product and platform restrictions: which contracts are tradable and which platforms are supported, which also decides what automation is possible.

A trailing drawdown is the rule to build the plan around

A static maximum drawdown measures from your starting balance and stays put. A trailing drawdown moves up with you: each new equity high lifts the level at which you are disqualified. Forex traders rarely arrive prepared, because a forex challenge usually anchors that floor to the initial balance, so nothing in the old plan accounts for a threshold that follows you.

There is more than one design in use and the difference is not cosmetic. Some thresholds follow intraday peak equity, so unrealized profit you never banked still lifts your floor. Others follow the end of day balance, so only closed results move it. Some stop trailing once the buffer reaches a set size, after which the account behaves like a static one. Which design applies to your account is the entire risk model, so confirm it in Topstep's current documentation rather than in a forum thread.

Once a threshold trails, your real risk budget is never the number printed on the account. It is the distance between current equity and the current threshold, and it moves every time you make a new high. Under an intraday design you can be disqualified without a single losing closed trade, purely by letting a large open profit give itself back.

The habit to build is simple and unnatural. Before each session, calculate the current buffer and size around it, not around the account. When a trade runs deep in your favour, note that you may have just raised your own disqualification level. If the mechanic is new, read trailing drawdown explained and daily loss versus maximum drawdown.

The trading day does not end where a forex trader thinks it does

Futures trade nearly around the clock during the week, but the day is defined by the exchange session and a daily settlement, not by midnight where you live or your old broker's server clock. There is a maintenance break and a settlement time, and an evaluation generally counts trading days against that calendar rather than your local one. People lose a qualifying day, or accidentally open a new one, by mapping the clock wrong, so confirm the boundary your account uses.

The expiry calendar has no forex equivalent either. Contracts expire and volume rolls to the next delivery month on a published schedule, so trading the month everyone else has left gives you thin books and poor fills. Scheduled releases matter here too. Because everyone trades the same central order book, thin liquidity around them shows up in the book itself, as gaps, a wider bid ask and slippage, rather than as a quote your broker widened for you.

Whether you may hold through the close, through the break, or overnight at all is firm policy, it varies by account type, and it can differ between the evaluation and the funded stage. Confirm the current cutoff in Topstep's own rulebook, then set an alarm for it rather than trusting yourself to remember with a position open.

Forex habits that carry over badly

Early damage in futures is often not a strategy failure. It is a transplanted habit.

  • Averaging down and grid style recovery. In forex a floating loss can sit for days. Under a daily limit and a trailing threshold, an open loser can end the account this afternoon.
  • Thinking in spread instead of round turn cost. Futures typically charge commission per contract per side plus exchange and regulatory fees, and often a data subscription, so cost scales with contracts and frequency. A plan priced on raw forex spread can be unprofitable before the edge is tested.
  • Treating a micro contract as a rounding error. A micro is smaller, not harmless. Volatility per point does not shrink because your contract did.
  • Carrying the swing habit. Many futures evaluations expect a flat book at the close, so a plan that survived overnight on a forex account may be disallowed.
  • Trading correlated contracts as if that were diversification. Two index products often behave like one position with two names.
  • Assuming automation is permitted. Policy differs by firm, account stage and platform, so ask in writing before connecting anything.

Rebuild the risk layer backwards from the rulebook

The method that travels well from forex to futures is not a setup, it is a sequence. Build the constraints first and let them decide the trading.

  • Copy the current rules onto one page: target, daily limit, drawdown type and how it trails, minimum days, contract cap, cutoff times.
  • Convert every rule into ticks and contracts for the products you trade. A rule you have not translated into your own units is a rule you will break under pressure.
  • Set a personal daily stop well inside the firm's limit and a contract ceiling well inside the cap. The firm's number is a cliff edge, not a target.
  • Define per trade risk as a fraction of the buffer to the drawdown threshold, and recalculate it every morning.
  • Decide in advance what ends the session: a loss number, a profit number, a trade count, a time. Whichever arrives first.
  • Grade each session on the rules you followed, not on the profit and loss you happened to get.

Where automation helps, and where it does not

Automation is attractive here for a specific reason. The rules that end futures accounts are arithmetic, and arithmetic is what a human stops doing well after a red morning. A process tracking the buffer does not decide that this one time is different.

Be honest about platforms, though. PraxAI's robot runs natively on MT4, with MT5, cTrader, Match Trader, TradeLocker and DXtrade through a copier. That is the forex platform stack, not the futures one, so this is not a pitch for plugging PraxAI into a Combine. What transfers is the design principle. PraxAI GUARD monitors the firm's rules in real time, and the built in drawdown lock stops trading before the firm's daily loss limit is touched, that limit specifically and not a trailing maximum. When a firm changes a rule, the robot is updated within 48 hours. Whatever you run on futures, ask the same three questions. Does it know the live threshold, does it stop itself, and does it get updated when the rulebook does.

Passing is the audition, the funded account is the job

The Combine gets most of the attention because it is the part you pay for, but it is the easier half. Only 1 to 3 percent of funded traders keep the account, and the reason is rarely a broken strategy. It is a funded stage with its own rulebook, or a trader still working a funded account with evaluation urgency.

So build the account you want to keep from the first session. Sizing that respects the buffer instead of the balance, a cutoff you obey on the days that are going well, and a routine you can repeat once the target is behind you. That is the thinking behind PraxAI FUNDED, the second engine that guards an account after funding, and it is the right posture whether you automate or not. Bots do not die in the challenge. They die in the rulebook, and a futures rulebook leaves less room to be wrong about the arithmetic.

Frequently asked questions

Is a Topstep Combine harder than a forex prop firm challenge?

It is different rather than simply harder. The rule categories are similar, but futures sizing is discrete, the trading day is set by the exchange session, and futures evaluations commonly use a drawdown that trails your equity high instead of sitting at your starting balance. Confirm which design your account uses, then plan for those three differences before you spend any energy on the profit target.

What is a trailing drawdown in a futures evaluation?

It is a disqualification level that rises as the account makes new highs. Designs vary. Some follow intraday peak equity including unrealized profit, some follow the end of day balance, and some stop trailing once the buffer reaches a set size. Confirm which one applies in the firm's current rulebook, because it changes how you size every trade.

How many contracts should I trade in a Combine?

Fewer than the cap. Start from the distance between your equity and the drawdown threshold your account uses, decide what fraction of that you will risk on one trade, then check how many ticks of stop the product's tick value allows at one contract. If one contract already risks more than your plan permits, trade a smaller product, not a tighter stop than the instrument respects.

Can I use a trading bot or EA on a futures prop account?

It depends on the firm, the account stage and the platform, and policies change, so ask support in writing and read the current rulebook rather than trusting a forum post. Our general overview of whether prop firms allow trading bots covers the wording to look for in the terms.

Do I have to close my futures positions before the end of the day?

Many futures evaluations expect a flat book before the daily close or the maintenance break, and some allow overnight positions only on certain account types. That is firm policy rather than an exchange rule, so verify the current cutoff for your specific account and set an alarm for it.

What do forex traders get wrong when they switch to futures?

Three things carry over badly: tolerance for floating losses, adding to losing positions, and sizing by habit instead of by tick value. In forex an open loser can sit for days. Under a daily loss limit and a trailing threshold, that same open loss can end the account in one session. For how the two major futures programs differ on exactly these rules, see Apex vs Topstep.

Does PraxAI work on Topstep?

PraxAI's robot runs natively on MT4, with MT5, cTrader, Match Trader, TradeLocker and DXtrade supported through a copier, which covers the forex side of the prop industry rather than the futures platform stack. Check the current platform list on praxai.io before buying anything for a specific firm.
