Topstep Maximum Contracts 2026: Per-Account Limits Explained

Topstep maximum contracts caps how much position size you can hold open at once, and the cap works differently at each stage. In the Trading Combine it is fixed by account size: 5 minis on $50K, 10 on $100K, 15 on $150K, with one mini counting as ten micros. In the Express Funded Account there is no fixed cap. The Scaling Plan sets maximum position size from your current balance, and because an XFA starts at $0, a $150K XFA opens at 3 lots rather than 15. The Live Funded Account returns to fixed starting limits of 5, 10 and 15 lots by size, with expansion only from $100,000 in profit onward.

For the wider rules picture see the Topstep rules overview; for the drawdown math that pairs with these caps see the drawdown explainer.

What are Topstep's verified contract caps?

Topstep publishes the per-size limits in Help Center article 8284197 and on the topstep.com/topstep-prop product page. As of August 2, 2026 the matrix is:

Trading Combine caps, and the Scaling Plan that replaces them in the XFA

The Combine caps do not carry into the Express Funded Account. The XFA replaces them with the Scaling Plan, shown in the second table, which reads your current balance rather than the label on the account. Because an XFA starts at a $0 balance, the first sessions are the tightest you will trade on it, and the limit never rises mid-session: cross a threshold and the extra size arrives with the next session. For the full Combine spec see the trading combine deep-dive; for XFA mechanics see the express funded account guide.

Live Funded Account (real money tier)

The Live tier does have a fixed starting limit, and it also has a safeguard that can tighten it:

• Maximum position size at the start: 5 lots on a $50K, 10 on a $100K, 15 on a $150K.
• 20% of your combined XFA balances is tradable at the start, 80% sits in reserve, with a $10,000 minimum starting balance.
• The reserve unlocks in four increments of 25%, each at a profit threshold equal to the size's Combine profit target ($3,000 / $6,000 / $9,000).
• Safeguard: a tradable balance at or below $10,000 drops the maximum position size to 5 lots, at or below $5,000 to 3 lots.

In practice a fresh Live Funded trader starts close to the $10,000 minimum tradable balance, which trips the safeguard and puts the maximum position size at 5 lots whatever the account is labelled. The 5 / 10 / 15 starting limits stay in place until Tier 4 at $100,000 in profit, after which Dynamic Live Risk Expansion raises them to 30, 50, 70 and 100 lots at $100K, $200K, $550K and $1M in profit. Thirty winning Live days of $150 or more unlock daily payouts, not extra size. For the full Live tier mechanics see the live funded account guide.

How do minis and micros count toward the cap?

Most active futures contracts come in two sizes: a mini (the standard retail-tradable size) and a micro (one-tenth the dollar exposure). Topstep enforces caps in micro-equivalents, so understanding the conversion matters before sizing anything.

Common Topstep instruments and their conversions:

The pattern is consistent across CME products: 1 mini = 10 micros in dollar exposure. A trader holding 1 ES has the same per-point P&L as a trader holding 10 MES.

This is the standard CME conversion that Topstep, YRM, Apex, and most futures props all use. Topstep names three exceptions to it: Micro Silver (SIL) runs 5:1 against Silver and counts as two of any other micro, and Micro Bitcoin (MBT) and Micro Ether (MET) are capped at mini-equivalent lot sizes rather than standard micro scaling. Outside those three the 10:1 ratio applies. For platform mechanics see the Topstep review.

What does trading 5 minis mean on a $50K Combine?

The $50K is the most-purchased Combine size and the size I trade. Combine cap: 5 minis or 50 micros. Maximum Loss Limit: $2,000, trailing the end-of-day balance and checked in real time.

Worked example using ES at $50 per index point:

• 5 ES minis = $250 of P&L per ES point of movement.
• The $2,000 trailing MLL therefore equals 8 ES points of buffer at full size before a hard breach.
• A typical cash-session ES range is 15-30 points; 8 points is one badly timed entry on a high-volatility day.

Working sizing math at smaller positions:

• 1 mini at $50/point: 40 points of buffer against the $2,000 trailing MLL. Generous.
• 2 minis at $100/point: 20 points of buffer. Workable for most setups.
• 3 minis at $150/point: 13 points of buffer. Tighter, requires good entry timing.
• 5 minis at $250/point: 8 points of buffer. Margin for error very thin.

Trading at the 5-mini cap is a deliberate choice for high-conviction entries with hard stops, not a default position size. On the consistency rule (50% best-day ceiling), maxing out the cap on a green session also risks producing an outsized winner that breaks the consistency math even if the trailing MLL holds. See the consistency rule article.

My experience: $50K Combine, 1-2 minis as default

I've traded Topstep on the $50K Combine since 2023 and pulled multiple payouts across Combine and XFA cycles. My typical position size: 1-2 ES minis. I rarely max out the 5-mini cap, and when I do it's a single high-conviction setup with a stop already pre-defined.

The math behind that choice mirrors the buffer table above:

• 1 ES mini at $50/point gives 40 points of MLL buffer.
• A standard losing day for me runs 5-10 ES points against position before I cut, leaving 30+ points remaining.
• 2 minis halves the buffer to 20 points. Still livable on most setups.
• 5 minis drops it to 8 points, too tight for the way I size stops.

Most setups I trade need 1-2 minis to express the idea. Sizing up to 5 doesn't make a marginal entry better; it just compresses the room to be wrong. Across three years of $50K Combine trading the discipline of staying at 30-50% of the cap kept the account out of trouble through a lot of noisy sessions. For sizing strategy across instruments see the first-payout strategy and the best strategies guide.

How combinations work within the cap

The micro-equivalent counting opens combo flexibility many traders don't initially exploit. On a $50K Combine with 50 micro-equivalents available, valid combinations include:

• 5 minis + 0 micros
• 4 minis + 10 micros
• 3 minis + 20 micros
• 2 minis + 30 micros
• 1 mini + 40 micros
• 0 minis + 50 micros

Anything that sums to 50 micro-equivalents or fewer is permitted. Across multiple instruments the same logic applies.

On a $100K Combine (100 micro-equivalents):

• 4 ES minis (40 micros) + 60 MNQ (60 micros) = 100
• 5 ES + 5 NQ = 50 + 50 = 100
• 2 GC + 4 CL + 40 MES = 20 + 40 + 40 = 100

The flexibility supports multi-instrument trading without artificial per-symbol caps. The most common miscount: forgetting that two opposite-direction positions in different products both consume cap. Long 4 ES and short 4 NQ counts as 80 micro-equivalents on a $100K account, not zero, even though the dollar deltas partially offset.

What happens when you hit the limit

The platform enforces the cap at order entry. If your current open positions plus the new order would exceed the ceiling, the order is rejected. It does not partial-fill, does not silently pass through, and does not register as a rule breach.

What this looks like in practice:

• No fee for trying.
• No account closure or warning ticket.
• No fill that quietly bypasses the check.
• The order does not transmit to the exchange.

The cap functions as a pre-trade risk check, which is why most attempts to exceed it never reach the exchange. It is not an absolute guarantee. Topstep's Scaling Plan article covers the case where an overage does land: errors corrected in under 10 seconds are ignored, but leaving too many contracts on for 10 or more seconds can put the account under review. Check your net exposure after a fill rather than assuming the platform did it for you. For platform behaviour see the trading platforms guide.

Topstep vs YRM vs Apex: contract caps compared

A direct comparison on the $50K and $150K sizes across major futures props:

Topstep sits in the middle of the futures-prop market on contract sizing. The 5-mini cap on $50K is not aggressive (Apex offers double) and not punitive (YRM Instant Prime offers less than half). It's the standard the older futures props converged on. For the peer firm profiles see the Apex Trader Funding review and the YRM Prop review.

How the cap interacts with other rules

The contract cap is one of three structural risk controls Topstep stacks on top of each other:

1. Contract cap (this article): hard ceiling on open exposure.
2. Daily Loss Limit: an optional add-on picked at checkout, when you buy the Combine or when you activate or reactivate an XFA, $1K / $2K / $3K, resets 5 PM CT, auto-liquidates at the line. Not a rule violation, it puts the account in a temporary violation for the rest of the session. In the Live Funded Account it is automatic and mandatory.
3. Maximum Loss Limit: $2K / $3K / $4.5K, trailing the end-of-day balance in both the Combine and the XFA and never moving down. Monitored in real time on realized and unrealized P&L, so it can break mid-session. Breach closes the account.

The three rules interact at the position level. A trader at 5 minis on the $50K hits the trailing MLL faster than a trader at 1 mini, because the per-point exposure is 5x. A trader at the cap also moves through the daily DLL faster on a losing day. Sizing inside the cap is the lever that lets you stretch the drawdown rules across more trading days. For the full drawdown explainer and payout rules see those articles.

When choosing your size matters more than choosing your cap

The contract cap on a Topstep account is a function of size, not a knob you adjust separately. Pick a $50K Combine and you get 5 minis; pick $150K and you get 15. The size you buy is the only lever for changing the cap.

For most traders new to Topstep, the $50K is the right starting Combine even if you can afford the $150K. The cap is plenty for typical retail strategies, the activation fee and monthly are lower, and the smaller balance enforces tighter sizing discipline that translates to the larger account later. For the full size comparison see the account sizes article and the pricing breakdown.

The traders who benefit from the $150K cap are those running multi-instrument portfolios where 5 minis isn't enough headroom for two or three concurrent setups. If you're trading one instrument at a time on a single thesis, the $50K cap is rarely the binding constraint. The trailing MLL is.

The bottom line

Topstep caps position size at 5/10/15 minis on $50K/$100K/$150K Trading Combines. The Express Funded Account does not inherit those numbers: its Scaling Plan reads the current balance, so a fresh XFA opens at 2 or 3 lots and works up. One mini equals ten micros (standard CME conversion), with Micro Silver, Micro Bitcoin and Micro Ether as the named exceptions, so combinations within a single micro-equivalent total are allowed. Orders that exceed the cap are rejected at the platform with no fee, though an overage left on for 10 or more seconds can still be reviewed. Live Funded accounts start at fixed 5/10/15 limits and expand only from Tier 4 at $100K in profit, with the reserve unlocking separately in 25% steps at profit milestones equal to the Combine profit target. For most traders the cap is the ceiling, not the target; sizing 30-50% of the cap leaves enough MLL buffer to survive normal losing days. Pick your Combine size partly on whether you actually need the extra mini room; the $50K is a sane starting point for nearly all single-instrument strategies. For the broader picture see the Topstep main review and the Topstep FAQ.

Frequently Asked Questions

What is the maximum number of contracts on a Topstep $50K Combine?

5 minis or 50 micros, or any combination that sums to 50 micro-equivalents or fewer. The Help Center (article 8284197) lists the cap explicitly. One mini equals ten micros in dollar exposure, so 3 minis plus 20 micros is also valid (30 + 20 = 50). The Express Funded Account that follows does not keep that ceiling. It uses the Scaling Plan instead, which starts a 50K XFA at 2 lots and reaches 5 lots once the balance passes $2,000.

Do the contract caps apply to the Express Funded Account too?

No. The Express Funded Account replaces the fixed cap with the Scaling Plan, which sets maximum position size from your current balance. A $100K XFA starts at 3 lots on a $0 balance, moves to 4 lots at $1,500, 5 at $2,000 and 10 at $3,000. The limit never rises mid-session: cross a threshold and the extra size arrives with the next session. A payout that drops the balance into a lower band lowers the limit again.

How does the Live Funded Account contract limit work?

The Live Funded Account does use a fixed starting limit: 5 lots on a $50K, 10 on a $100K, 15 on a $150K. Those hold until the account reaches Tier 4 with $100,000 in profit, after which Dynamic Live Risk Expansion raises them to 30, 50, 70 and 100 lots at $100K, $200K, $550K and $1M in profit. A safeguard works the other way: a tradable balance at or below $10,000 drops the limit to 5 lots, at or below $5,000 to 3. Separately, 20% of your combined XFA balances is tradable at the start with 80% in reserve, and the reserve unlocks in four 25% increments at profit thresholds equal to the size's Combine profit target ($3,000/$6,000/$9,000).

What's the difference between a mini and a micro futures contract?

A mini is the standard retail-tradable futures contract. A micro is one-tenth the dollar exposure. ES (E-mini S&P 500) is $50 per index point; MES (Micro E-mini S&P 500) is $5 per point. Trading 10 MES gives the same per-point P&L as trading 1 ES. Topstep counts contracts in micro-equivalents internally and enforces the ceiling against the total.

How does Topstep count contracts when I trade multiple instruments simultaneously?

Every open contract converts to its micro-equivalent and adds to a single running total. On a $100K Combine with a 100-micro cap, 4 ES minis (40 micros) plus 6 NQ minis (60 micros) lands at exactly 100. Adding any further contract gets rejected at order entry. The cap covers total open exposure across all symbols at any moment, not one position per instrument.

What happens if I try to place an order that exceeds the cap?

The order is rejected at the platform before it transmits. No silent breach, no fee, no rule violation logged. The trade simply does not fill. Topstep's contract cap behaves as a pre-trade risk check rather than a post-trade audit, so you cannot accidentally cross it. If a position is open in your account, by definition it sits within the cap.

Can I trade full-size (non-mini) contracts at Topstep?

Yes, for a large part of the list. Topstep's permitted products include full-size contracts such as Crude Oil (CL), Natural Gas (NG), Gold (GC), Silver (SI), Copper (HG), Platinum (PL), the CBOT grains (ZC, ZW, ZS, ZM, ZL) and the whole Treasury complex (ZT, ZF, ZN, TN, ZB, UB), plus full-size FX futures such as 6E and 6J. What is not on the list is the big S&P 500 (SP), so US equity index exposure runs through E-mini and Micro E-mini contracts only. Position limits are stated in mini-contract equivalents at a 10 to 1 micro ratio, and Topstep publishes no separate conversion for full-size products. Note also that current risk adjustments put Silver, Copper and Platinum at a zero position limit and cap Gold and Crude Oil at 3/6/9 by account size. TopstepX is the only trading platform, and Quantower can connect to it with TopstepX credentials.

Which instruments can I trade within the Topstep contract cap?

TopstepX lists 50+ futures across indices (ES, NQ, RTY, YM), energy (CL, NG), metals (GC, SI), currencies (6E, 6B, 6J), agriculture, and fixed income. The cap applies across instruments, but Topstep tightens individual products during periods of high volatility. As of August 2, 2026 the published adjustments for the Combine and XFA run RB, HO, CL and QM at 3/6/9 by account size, MCL at 30/60/90, Gold at 3/6/9, MGC at 30/60/90, Micro Silver and Micro Copper at 2/4/6, and Silver (SI), Copper (HG) and Platinum (PL) at zero. Check the current risk-adjustment list before sizing in those products. ES, NQ and RTY count as 10 micro-equivalents per mini.

Does the contract cap interact with the consistency rule?

Indirectly. The 50% consistency rule says your best winning day must stay at or below 50% of the Profit Target, so $1,500 on the $50K. Maxing out the contract cap on one good day produces an outsized winner that risks tripping consistency, even though the contract cap itself was respected. Most Topstep traders deliberately size below the cap to keep daily P&L distribution flatter. See the consistency rule article for the math.

Can I scale into a position past the cap if I close part of it later?

No. The cap is enforced on total open exposure at any moment. If you hold 5 ES minis on a $50K Combine, you've used the full 50-micro ceiling; you'd need to flatten some before adding more. Once you reduce, the platform allows fresh exposure up to the same 50-micro line again. The cap recalculates continuously based on current open contracts.

Are Topstep's contract limits stricter than Apex or YRM?

Topstep matches YRM Starter on the $50K size (5 minis each). Apex is looser at the $50K size (10 minis at the 4.0 program), positioning Apex as the higher-volume option. YRM's Instant Prime $150K is meaningfully tighter than Topstep $150K (7 minis vs 15). Topstep sits in the middle of the market: not the loosest cap, not the tightest. See the Apex vs Topstep comparison for fuller context.

Does the contract cap change as the Combine balance grows?

In the Trading Combine, no. The cap is set by account size and stays fixed: growing a $50K Combine to $54,000 does not unlock more minis, and to trade larger size you would take a bigger Combine. In the Express Funded Account the opposite is true. The Scaling Plan raises your limit as the balance grows and lowers it again if a payout drops you into a lower band, and any change takes effect from the next session, never mid-session.
