Two of the most-discussed futures firms live or die on one number: your trailing drawdown. Topstep and TradeDay both use it, but the way that line moves under your account — and when it stops moving — is where most traders quietly blow up.
Trailing drawdown: how each computes it
The single mechanic that decides your survival is how the maximum loss limit trails your equity. Both firms use an intraday-style trailing threshold on the evaluation, which means the line chases your account higher as your open profit grows — not just your closed balance.
- On Topstep, the trailing drawdown follows your peak unrealized equity during the evaluation, then locks once you clear a fixed buffer above your starting balance. After it locks, it typically behaves like a static floor rather than continuing to trail.
- On TradeDay, the concept is similar — an end-of-day or intraday trail depending on the program you pick — and the point at which it freezes is again tied to hitting a set cushion of profit.
The trap is identical on both: a trade that runs deep into profit and then gives it all back drags the trailing line up with the peak, so a “breakeven day” can leave you closer to violation than when you started. If you don’t have that mechanic reflexive, read the primer on how trailing drawdown actually moves, then model your own worst-case with the prop-firm drawdown calculator before you place a single contract.
Daily loss limits compared
Beyond the trailing max, each firm layers a daily loss limit that resets every session. This is the guardrail that ends your day early, and it’s often the one traders forget exists until it triggers.
- Topstep enforces a daily loss cap on the evaluation that is checked on unrealized equity, so a spike against you mid-trade can lock you out even if you intended to hold.
- TradeDay applies a comparable daily stop-out; the exact figure scales with account size.
The practical difference is less the number and more the enforcement feel. Both will flatten you or freeze the account when the line is touched. Neither cares about your thesis. Confirm the current numbers and whether the check is on realized or unrealized equity directly with the firm — these values get revised, and the intraday-vs-EOD distinction changes how tight you must trade.
Evaluation targets and account sizes
Both firms sell a ladder of account sizes, and the profit target to pass scales roughly with the size you buy.
| Dimension | Topstep | TradeDay |
|---|---|---|
| Evaluation style | Single-phase, simulated | Single-phase, simulated |
| Account sizes | Small → large tier ladder | Comparable tier ladder |
| Target scaling | Grows with account size | Grows with account size |
| Min trading days | Yes, a floor applies | Yes, a floor applies |
Both require a minimum number of trading days, which quietly rewards patience — you cannot pass in a single lucky session even if you hit the target. Size the challenge against your realistic weekly output, not the biggest payout tier. Run the target and the drawdown together to see if the math is survivable for your style; details shift, so verify the live figures on each firm’s page: Topstep · TradeDay.
Path to funded and payout terms
Passing is the start, not the finish. On the funded side both firms introduce their own rhythm.
- Topstep moves you to a funded account with its own trailing drawdown behavior, a profit split that favors the trader, and a payout process that unlocks after you bank a first cushion of profit.
- TradeDay similarly transitions you to a funded stage with a split and a payout cadence, and — like most firms — early payouts tend to carry consistency and minimum-day conditions.
The universal caveat: first payouts almost always have the most strings attached (minimum trading days, a consistency check, sometimes a buffer you must leave in the account). Treat the marketing split as the ceiling, not the guarantee, and read the payout terms line by line before you celebrate.
Rules that most often trip traders up
- Riding a winner into the trail. Letting open profit peak then evaporate ratchets your trailing line up permanently on the evaluation.
- Holding through the daily limit. An unrealized spike can lock the account before your stop fills.
- Ignoring the minimum-days floor. Hitting target in three sessions still isn’t a pass.
- News-event gaps. A position through a high-impact release can breach both limits at once.
- Copying size across accounts unevenly. If you run several evaluations at once, one oversized fill can violate one account while the others sit fine.
That last point is where a lot of multi-account traders lose accounts they didn’t need to. Shibiki pushes hard risk limits down to the broker so a max-loss line is enforced even when you’re not watching, mirrors position sizing across every prop account you copy to, and auto-journals each fill so you can see — after the fact — exactly which trade dragged the trail. Its live edge-health readout wraps your expectancy in a Wilson confidence interval, so you know whether a good week is signal or variance before you scale into the next account.
Which firm is more forgiving
There is no universal winner — it depends on how you trade. A scalper who closes flat every session and rarely lets winners breathe will find the trailing mechanic on either firm nearly invisible. A swing-style futures trader who holds through sessions is more exposed to intraday trailing and daily-limit checks, and should favor whichever firm’s current rules check on realized rather than unrealized equity.
Decide by your holding period first, price and payout second. Then confirm every number — targets, drawdown type, minimum days, payout conditions — on the firm’s own page, because these terms change more often than the comparison blogs update.
