Topstep XFA Scaling Plan: Contract Limits and Rules
How the Topstep XFA Scaling Plan sets your maximum position size by account balance, including micro/mini ratios, special products, and session timing rules.
According to Topstep, the Scaling Plan is an Express Funded Account (XFA) objective that sets your Maximum Position Size — the maximum contracts you can hold at one time — based on your current account balance. It applies to both the XFA Standard and XFA Consistency payout paths, and does not apply to the Live Funded Account, where it has been replaced by Dynamic Live Risk Expansion. This page covers the Topstep XFA Scaling Plan as documented by Topstep; for a broader look at Topstep’s account structure, see the Topstep review and the Prop Firm Rules index.
What Is the Topstep XFA Scaling Plan?
According to Topstep’s Scaling Plan help article, the Scaling Plan is an Express Funded Account (XFA) objective. It defines your Maximum Position Size — the maximum number of contracts you can hold open at any one time — and that ceiling is determined by your current account balance, not a fixed number set at account opening.
Topstep states clearly that the Scaling Plan does not apply to the Live Funded Account. In the Live Funded Account, position sizing is governed by a separate mechanism called Dynamic Live Risk Expansion. Traders moving from an XFA to a Live Funded Account should note this distinction, because the rules that govern how many contracts they can hold change entirely at that transition.
The Scaling Plan applies to both XFA payout paths — Standard and Consistency — making it a universal XFA rule rather than a path-specific one. Traders who are evaluating which payout path to pursue should understand that neither path exempts them from the Scaling Plan. For context on how the two paths differ in other respects, see the Express Funded Account Parameters page published by Topstep.
How Contract Limits Are Determined
According to Topstep, the XFA starts at a $0 balance. As profits accumulate from trading, the account balance grows, and the Scaling Plan translates that growing balance into a higher Maximum Position Size. Topstep describes this as buying power expanding alongside the balance.
A critical operational rule governs when that expanded buying power becomes available: contract limits do not increase mid-session. If a trader’s balance crosses a threshold during a live session that would ordinarily unlock a higher contract limit, that higher limit does not take effect until the next session begins. Traders who hit a threshold late in a session must wait before trading the larger size.
Topstep also states that traders are never required to trade their maximum allowed contracts. The Scaling Plan sets a ceiling, not a floor. A trader whose balance qualifies them for a 5-lot limit can still trade 1 or 2 lots without any issue. This matters practically: newer XFA traders who are still building consistency may prefer to trade well below their ceiling to manage risk, and the rules permit that. The Scaling Plan is described by Topstep as a guide to responsible leverage on a growing account, with over-leveraging identified as a primary cause of long-term damage to trading performance.
Micro and Mini Contract Ratios
According to Topstep, contract limits under the Scaling Plan are expressed in mini-contract equivalents, and the standard conversion ratio between micros and minis is 10:1 — meaning 1 Mini equals 10 Micro contracts.
Topstep provides a documented example: on a $50K XFA with a 2-lot Scaling Plan limit, a trader may hold 2 Minis, or 20 Micros, or any combination of minis and micros that equals 2 mini-contract equivalents. A hypothetical combination example: 1 Mini plus 10 Micros would equal exactly 2 mini-contract equivalents and would be within the limit. Holding 1 Mini and 11 Micros would equal 2.1 mini-contract equivalents and would exceed it.
Topstep notes that the Micro to Mini ratio functionality is available for the Trading Combine and the Express Funded Account, but is not currently available for the Live Funded Account. Traders who use micro contracts exclusively should be aware that their position count is still measured against the mini-equivalent ceiling, so a 2-lot limit means a maximum of 20 micro contracts across all open positions, not 20 minis. For more detail on how micro contract scaling works specifically, see Topstep Scaling Plan Micros.
Special Product Weightings
According to Topstep, certain products do not follow the standard 10:1 micro-to-mini ratio and carry non-standard weightings under the Scaling Plan. Traders who include these products in their XFA trading need to account for their different counting rules when calculating net exposure against their limit.
| Product | Scaling Rule |
|---|---|
| Micro Silver (SIL) | 5:1 ratio vs. Silver (SI); counts as 2 of any other micro |
| Micro Bitcoin (MBT) | Capped at mini-equivalent lot sizes, not standard micro scaling |
| Micro Ether (MET) | Capped at mini-equivalent lot sizes, not standard micro scaling |
The practical consequence of these weightings is that a trader holding Micro Silver alongside standard micro contracts will consume their limit faster than they might expect. For example, if a trader’s limit is 2 mini-contract equivalents and they hold 1 Micro Silver (SIL), that single contract counts as 2 standard micros — consuming one-tenth of a mini-equivalent more than a standard micro would. Traders combining these special products with standard contracts should calculate their total weighted exposure carefully before entering positions.
Scaling Plan on Both XFA Payout Paths
According to Topstep’s Express Funded Account Parameters page, the Scaling Plan is a stated objective on both XFA payout paths. The comparison table published by Topstep shows a checkmark for the Scaling Plan under both XFA Standard and XFA Consistency columns, confirming neither path is exempt.
For the XFA Standard path, Topstep states the objective as: follow the Scaling Plan — the max contracts you can hold at one time — based on your current account balance. The same wording appears for the XFA Consistency path. This means that regardless of which payout structure a trader selects, exceeding the Maximum Position Size set by the Scaling Plan is a rule violation on both paths.
The two paths differ in their payout eligibility criteria — Standard requires 5 winning days with at least $150 profit each, while Consistency requires 3 trading days and a consistency target of 40% or below — but the Scaling Plan obligation is identical across both. Traders who switch between paths or who are deciding which path to pursue should not assume that one path offers more flexibility on position sizing. For more on the Consistency path’s specific calculation, see Topstep Consistency Rule.
Error Tolerance and Compliance
According to Topstep, there is a defined tolerance window for accidental oversize positions: errors corrected in under 10 seconds are ignored. If a trader accidentally enters a position that exceeds their Maximum Position Size but reduces it to within the limit in fewer than 10 seconds, no action is taken. However, if the oversize position is held for 10 or more seconds, the account may be reviewed.
Topstep advises traders to know their net exposure and correct it fast. This 10-second window is narrow in live market conditions, particularly during fast-moving sessions, so relying on it as a routine safety net is not a sound approach. Topstep recommends three practical steps to avoid exceeding the Scaling Plan in the first place: set up the trading workspace to display open positions and pending orders at all times; enable Order Confirmation, which requires reconfirming before an order submits; and use the Contract Limits feature in the Risk Settings page to set a per-product maximum.
Traders can view their current contract limits on the TopstepX Risk Settings page, which shows the contracts available for the next session — not the current session. This is consistent with the session timing rule: limits update between sessions, so the Risk Settings page reflects what will be available when the next session opens, not a real-time intra-session figure. Note that exceeding the Scaling Plan is not the only way to violate XFA rules; other account rules such as the Maximum Loss Limit remain independently enforceable.
Volatility and Position Limit Adjustments
According to Topstep, during periods of extreme volatility, Topstep may temporarily tighten position limits on affected products. This means that even if a trader’s current account balance qualifies them for a specific Maximum Position Size under the standard Scaling Plan table, that limit could be reduced on particular instruments during volatile market conditions.
Topstep does not specify in the Scaling Plan article which products are subject to temporary tightening, how much limits may be reduced, or how long such adjustments last. The absence of that detail in the documented source means those specifics are not confirmed here. Traders should treat the standard Scaling Plan limits as the baseline under normal conditions, with the understanding that Topstep reserves the right to apply tighter limits when market conditions warrant it.
The practical implication is that a trader who plans a position size based on their current balance-derived limit could find that limit reduced without advance notice during a volatile session. Monitoring Topstep’s communications and checking the TopstepX Risk Settings page before each session — which shows contracts available for the next session — is the most reliable way to confirm what limits are actually in effect.
