Topstep 50K vs 100K vs 150K: Which Account Size Should You Trade?
Compare Topstep's 50K, 100K, and 150K Trading Combine accounts by profit target, daily loss limit, and trailing drawdown — and learn how to journal each one.
Every Topstep Trading Combine account comes with three numbers that decide whether you pass, survive, or start over: the profit target, the daily loss limit, and the trailing maximum loss. The account size you pick sets all three — and it quietly sets your margin for error too.
This guide compares the three account sizes side by side and explains what each one means for how you should trade and journal. Topstep can change its parameters at any time, so treat the numbers below as the widely published figures at the time of writing and verify the current values on Topstep's Trading Combine parameters page before you buy.
The three account sizes at a glance
| Parameter | 50K | 100K | 150K |
|---|---|---|---|
| Profit target | $3,000 | $6,000 | $9,000 |
| Daily loss limit | $1,000 | $2,000 | $3,000 |
| Trailing maximum loss | $2,000 | $3,000 | $4,500 |
Two ratios in that table matter more than the raw dollars.
Target versus trailing drawdown. On the 50K, you must make $3,000 while never giving back more than $2,000 from your high-water mark — a 1.5:1 ratio. The 100K asks for $6,000 against a $3,000 trailing loss (2:1), and the 150K asks for $9,000 against $4,500 (also 2:1). The larger accounts give you proportionally more room per dollar of target, but the absolute swings are bigger too.
Daily loss limit versus trailing loss. On every size, two maximum-loss days in a row can put you at or near the trailing limit. The daily loss limit is not a budget to spend — it is a circuit breaker you should never plan to touch.
What the numbers mean in practice
The 50K: cheapest seat, thinnest cushion
The 50K's $1,000 daily loss limit is roughly two to four typical stop-outs on one or two ES or NQ contracts, depending on your stop size. That makes position sizing discipline the entire game: one oversized trade after a red morning can end the day, and two bad days can effectively end the account. If you journal one thing on a 50K, journal your size relative to your stop.
The 100K: the balance point
The 100K doubles the daily room and raises the trailing cushion to $3,000. For traders who trade 2–5 contracts with defined stops, this is usually the size where normal trade variance stops threatening the account on every losing streak. The target doubles as well, so the combine takes longer to pass if your sizing stays constant.
The 150K: room to breathe, more to lose
The 150K's $4,500 trailing loss is the largest cushion Topstep sells, and the $3,000 daily limit tolerates a genuinely bad session without ending the account. The trap is psychological: traders who move up from a 50K often scale their size faster than their skill. The rules are proportionally similar — the discipline required is identical.
Don't forget the rules that don't change with size
Every Topstep account, regardless of size, carries the same operational rules. The one that ends the most accounts while the trader is away from the screen is the daily flatten rule: all positions must be closed by 3:10 PM CT every weekday, with Topstep's risk team beginning to flatten shortly before. A journal that tracks rule adherence — not just P&L — will surface how close you routinely cut it.
Consistency expectations, scaling plans, and payout rules also apply after you pass. If you want the deeper treatment, read our guides to the trailing drawdown and consistency rules.
How to journal each account size
Whatever size you pick, the journal question is the same: how much of my loss room did today consume, and was that spending deliberate?
- Track remaining daily loss room and remaining trailing room as first-class numbers, per
account — not as an afterthought you compute when things go wrong.
- Record your planned size and your actual size on every trade. Size drift is the earliest
visible symptom of an account that is about to fail.
- If you trade multiple accounts with a copier, group mirrored fills into one decision for
your statistics while keeping every account's real dollars separate. Propfy does this automatically — see the Topstep trading journal workflow.
Frequently asked questions
Which Topstep account size is best for beginners?
Most traders start with the 50K because it costs the least per month, but its $1,000 daily loss limit leaves very little room for sizing mistakes. If your stop-outs regularly exceed $250, the 50K punishes normal variance. There is no universally best size — pick the one whose daily limit is at least three to four times your typical worst planned loss.
Is the Topstep 150K easier to pass than the 50K?
The ratios are close, not identical. The 150K asks for a $9,000 target against $4,500 of trailing room (2:1), while the 50K asks for $3,000 against $2,000 (1.5:1). The 150K gives proportionally more cushion per dollar of target, but only if the trader keeps position size proportional. Traders who scale size faster than skill lose the advantage immediately.
Does the daily loss limit reset every day?
Yes. The daily loss limit applies per trading day. The trailing maximum loss does not reset — it trails your account's high-water mark, which is why two heavy losing days in a row are far more dangerous than one.
Can I trade multiple Topstep accounts at once?
Topstep permits multiple accounts, and many funded traders copy one signal across several of them. If you do, review performance per decision, not per fill, or your statistics will count one trade as many. Our guide to journaling multiple TopstepX accounts covers the workflow.
Where can I verify the current Topstep parameters?
Always confirm the live values on Topstep's own site — the Trading Combine parameters article is the canonical source. Prop-firm rules change, and your journal should be checked against the rules you are actually trading under.
The size decision is a risk decision
Choose the account whose daily loss limit comfortably absorbs your worst planned day, not the one whose profit target flatters your ambition. Then journal the account the way the firm measures it: room remaining, rules followed, one correction per session. A journal built for Topstep accounts keeps those numbers in front of you before they become an email from the risk desk.
