Prop Firms That Won't Let You Change Strategy: Official Rules Checked | TradingCult Bans EAs Outright, Funded7 Disqualifies Running the Same EA Across Multiple Accounts [September 2026]

Note: Firm-specific rules are updated frequently. Prohibited strategies and news-trading rules in particular can be added or changed later, so always check each firm's official site. This article is based on each firm's official FAQ and terms pages, checked directly as of September 5, 2026.

There Are 3 Types of 'You Can't Change Strategy'

When I looked into whether you're allowed to change strategy mid-challenge, 8 firms were left where I couldn't confirm the official position. Having now closed that gap, it turns out "you can't change" breaks down into 3 distinct types.

Type 1: EAs simply aren't allowed. This is a question that predates changing your method at all.

Type 2: Keeping the same strategy is required in writing. Changing it at all is itself a violation.

Type 3: Your method is boxed in by a prohibited list, so there's effectively nowhere to change to. The individual prohibitions are so detailed that wherever you switch to, you hit the list.

How you deal with each is completely different. Let's go through them in order.

Type 1: TradingCult Bans EAs and Bots Outright

TradingCult is the most thorough about this. Its official FAQ says:

TradingCult encourages traders to showcase their skills and expertise without relying on automated trading algorithms, software, Expert Advisors (EAs), or bots.

It doesn't stop at "encourages" — it goes on to state explicitly that use is prohibited, and a violation is a hard breach that fails the challenge. This isn't a case of "only HFT-style EAs are banned" — automated trading itself is the target.

If you're building around automated trading, TradingCult is off the table from the start. This is a question that comes before whether you can even change methods.

The firm separately bans HFT and tick scalping too. Even manual high-speed trading isn't allowed.

Type 2: Firms That Require Keeping the Same Strategy in Writing

TradingCult: Inconsistent Trading Is a Prohibited Act

The firm's list of prohibited acts includes this:

Inconsistent Strategies: Trading without a consistent approach, either within a single account or across multiple accounts/challenges.

The distinctive part is that consistency is required even across accounts. Running a different method on each account could fall foul of this. It's exactly the opposite of The5ers, which requires "a different method on each account," so if you run both firms at once, your designs collide.

FundedNext: Switching From EA to Manual Is Banned

This matches what the previous piece found. The firm expects the same strategy to be maintained across the challenge and the funded account, and explicitly states that passing the challenge with an EA/bot and then switching to manual on the funded account (or vice versa) is prohibited.

Type 3: Firms Where the Prohibited List Effectively Boxes You In

Even if it says "strategy changes are free," if the prohibitions are detailed enough, there's nowhere left to change to. This is the part most people overlook.

Funded7: Even Your Own EA Fails You If It Resembles Someone Else's

Funded7's Rule 4 has a clause you don't see at other firms.

Even if using your own EA, if the results show a high correlation with other traders, it will be deemed Group Trading and lead to disqualification.

On top of that, copying positions between multiple Funded7 challenge accounts or Pro accounts is itself prohibited.

In other words, at this firm, running the same EA across multiple accounts doesn't work. Commercial and freely-distributed EAs are also specifically named and banned, because "every user gets the same entries." If you want to scale up to more accounts, each one needs different logic.

Blueberry Funded: A Major Change on March 12, 2026

At Blueberry, the rules are a completely different thing depending on when you bought and which plan. Mixing this up means judging by outdated information, so let's go through it in order.

For 1 Step, 2 Step, Instant Lite and Instant Elite bought on or after March 12, 2026, the lot-size limit has been removed and replaced with a "1.5% risk per trade idea" cap. The ceiling has shifted from an absolute lot amount to relative risk. The Prime challenge is exempt from this new rule and never had a lot-size limit to begin with.

And the following prohibitions have been removed from Prime (effective March 12, 2026):

• Gambling behavior and excessive one-sided bets
• Grid trading
• All-in trades (full leverage)

What remains on Prime is latency arbitrage, hedging against outside accounts, HFT, tick scalping, toxic trading flow, dishonest trading, and copy trading or third-party account management. As far as method restrictions go, this is now a fairly loose category.

On the other hand, accounts bought before March 12, 2026 keep the old rules as-is. Here are the ones that directly affect EAs.

Entering the opposite direction right after a loss is banned. After closing a losing trade, you have to wait at least 5 minutes before entering in the opposite direction. Breakout and counter-trend EAs commonly fire an opposite signal right after a stop-out.

One-sided bias is banned. Concentrating exclusively on buys or exclusively on sells, without diversification or analytical basis, is classified as "gambling."

A cap on the number of positions. Up to 4 at a time on the same currency pair, up to 7 across all instruments combined.

The martingale ban is broad in scope. "Increasing position size by 50% or more within the same session after a loss" and "entering a correlated asset at a larger size after a loss" are also violations.

The penalty, if caught during the evaluation, is that you can't be promoted to Funded; on a live funded account it's payout denial plus a reset to Phase 1. On Instant Funding accounts there is no warning — any deviation ends the account immediately.

Since the applicable rules depend on when you bought, first confirm which version your own account falls under. The official help center keeps the old and new versions as separate articles side by side; the one with "(before March 12, 2026)" in the title is the old version.

One more thing: EA operators need to watch for the hyperactivity rule. 10,000 server requests in a trading day triggers a warning email, and 20,000 automatically disables the account. If your implementation fires an order-decision on every tick, this is a number you can realistically hit.

SuperFunded: More Prohibitions Kick In Only at the Funded Stage

SuperFunded permits EA use itself. However, the following are banned specifically at the Funded Stage:

• HFT (whether manual or bot-driven)
• Tick scalping
• Scalping (allowed on 1 Step)
• Grid trading (allowed on 1 Step)
• Latency arbitrage / reverse arbitrage
• Martingale
• Data feed manipulation / use of a delayed feed

The parts in parentheses matter. Scalping and grid trading are allowed on the 1 Step challenge, but banned at the Funded stage. It's a structure where the method that got you through the evaluation can't be used as-is. If detected, the stated outcome is account termination.

The firm has one more clause with clear numbers: a ban on gambling-style trading.

The penalty is staged. First a warning email, and the profit from the trade in question is deleted. At the same time, an SL becomes mandatory on all orders, and the profit cap is extended by 3 rounds. A further violation ends the account and the contract.

2.5% per trade is a level you can't get complacent about even running at 2% risk. If you keep the same position size while your balance shrinks, the risk% per trade rises relative to the smaller balance. By the time you're down to the max 10% drawdown, that 2% works out to 2.22%, so building your position sizing around 2.5% risk means you're already right at the line from the start.

Firms That Ban 'Account Rolling'

There were 2 firms that explicitly ban the practice of buying and cycling through large numbers of challenges.

FundedElite has a dedicated explainer page on it.

Account rolling is a form of trading that comes very close to gambling. In this approach, a trader buys multiple trading challenge programs, trades aggressively or recklessly, and hopes that some of them succeed.

The firm gives three reasons — it "goes against sound trading principles," "produces low-quality trading data," and "undermines the integrity of the trading environment" — and states that as an anti-gambling policy, it does not accept account rolling.

TradingCult also has this in its prohibited list: "Account Rolling: Continuously purchasing multiple evaluation challenges and recklessly trading them undermines the integrity of your strategy."

Both definitions come with the qualifiers "aggressive" and "reckless," so running multiple accounts with a properly risk-managed method doesn't necessarily fall under this automatically. Still, it looks the same from the outside. If you're planning to scale up account count at either of these two firms, you should confirm the specifics with support before buying.

Firms Where the Rules Change Between Challenge and Funded

This is where the second half of the article begins. Here's a roundup of firms where something that was fine during the evaluation suddenly changes the moment you pass.

FundedElite's Strategy Risk Limit Applies Only at the Funded Stage

The official page opens with this:

This rule applies only at the funded stage.

The substance: "On any single trading day, taking on risk exceeding 50% of the daily loss limit on a single instrument is strictly prohibited." On an account with a 5% daily limit, you can only take up to 2.5% of risk per day on the same instrument.

Watch out — the way risk is calculated here is unusual.

• Without an SL, the risk is the maximum adverse excursion reached during the trade. It doesn't matter if you eventually close it in profit.
• With an SL, it's calculated from the furthest SL placement set during the trade. If you enter at 1% and later widen it to 2%, the risk counted is 2%.
• If both apply, whichever is higher is used.

A violation leads to closure of the funded account and forfeiture of accumulated profit. The firm lets you self-serve up to 3 account resets, but the fee is 40% of the original challenge fee (minimum $10) for the first, double that for the second, and double again for the third.

SuperFunded's News-Trading Rule Only Kicks In After You Pass

The official FAQ answer is blunt:

Yes, we allow news trading. However, at the funded stage, we do not allow news trading.

The window covers ±10 minutes around a high-impact release, and closing counts, not just opening. Simply continuing to hold a position that was opened outside the window isn't itself a problem, but closing it inside the window is a violation.

A method built during the evaluation without worrying about news stops working the instant you move to Funded. Hantec Trader has the same structure — there, it's Funded accounts only, ±3 minutes, and closing is also a violation.

News-Trading Rules Split on Whether Closing Also Counts as a Violation

This was the biggest find of this piece. Most firms with news-trading restrictions treat closing, not just opening, as a violation.

SL and TP orders sit on the broker's side. If one fills inside the window, you can't stop it yourself. So at firms where "closing is also a violation," the only option is to close the position before the window opens. What this table means is that an EA that merely blocks new entries isn't enough.

ThinkCapital's wording is the strictest — for the 4-minute window, all account activity is prohibited, including "closing, execution, hitting a stop loss, hitting a take profit," and a violation is stated to mean immediate breach, contract termination, and forfeiture of profit.

Within the same company, Blueberry is the exact opposite depending on the plan. On the standard plans, both opening and closing are banned, and hitting a TP or SL is also a violation. However, a January 27, 2025 update added a relief clause: a position that has been held for 6 hours or more before the release is not treated as a violation even if it hits its SL during the window.

By contrast, the official Prime challenge page states explicitly:

TP (take profit), SL (stop loss), and partial closes are always allowed regardless of the time window.

What's banned is only opening a new position; closing or adjusting existing positions is, if anything, encouraged as risk management. "A position opened before the release hitting its SL/TP during the news" is explicitly cited as an example of what's allowed.

Even within the same Blueberry, the EA implementation requirement changes depending on whether it's Prime or not. On Prime, just blocking new entries is enough; on the other plans, you need a mechanism to close out before the window.

And ThinkCapital has a News Trading add-on — buy it at purchase time and the news restriction is lifted for both the challenge and Funded. It's only available on Lightning and Nexus, not on Bolt. This was the only example of a rule you can pay to remove.

There's Also a Difference in Minimum Holding Time

If you're building short-term trading, this needs checking too.

Funded7's design is distinctive. A single instance isn't a violation — it's judged by ratio. After a downgrade, the risk cap per trade drops from 3.0% to 2.0% (Silver) or 1.0% (Bronze), and setting an SL becomes mandatory. You don't lose the account, but your operating freedom clearly drops.

Funded7's Risk Cap Is Grouped by Correlation

One more thing worth knowing about Funded7 is the risk cap at the Funded stage.

This cap applies with the same number to a single position, a correlation bucket, and the total portfolio, all alike. If you use 3.0% on one trade on a 3.0% account, you can't open any other position at all.

Correlation buckets group instruments together. US stock indices (US500, US30, US100) are one bucket, precious metals (XAUUSD, XAGUSD) are another, and major crypto (BTCUSD, ETHUSD) is another. Even if you think you've diversified across US30 and US100, you'll hit the cap on the combined total.

If you don't set an SL, risk is calculated statistically as ATR(14) × 1.96, which effectively limits your lot size. Also, if you move the SL mid-trade, the tier is judged by the furthest SL distance reached during the trade. Even if you entered at 1%, if you widen it later, you're judged on the widened value.

The handling on violation is named "asymmetric invalidation": profit from the violating trade is deleted, while a loss stays as-is.

How to Actually Confirm This Before You Buy

Here are the questions to send to support before buying, organized by purpose. Asking abstractly only gets you a vague answer back.

If you're using automated trading.

"Can automated trading with an EA be used at both the evaluation stage and on the funded account? If there are methods that can't be used, please tell me specifically which ones."

The trick is to name the stage explicitly when asking. This lets you spot in one shot a firm like SuperFunded where things change by stage.

If you're going to run multiple accounts.

"Is it possible to deploy the same EA across multiple accounts, using a different currency pair on each account?"

This flushes out firms like Funded7 that ban copying between your own accounts, and firms like TradingCult that require consistency across accounts.

If your method trades across news events.

"If an SL or TP fills around a major news release, does that count as a violation?"

This is the most important one. Asking "is news trading allowed?" only gets you an answer about opening new positions. Ask directly about how closing is treated.

Summary

There were 3 types of firms where you "can't" change strategy. TradingCult bans EAs themselves outright — this isn't even a question about method. FundedNext and TradingCult both require keeping the same strategy in writing, and TradingCult extends this even to consistency across accounts.

And at Funded7 and SuperFunded, the prohibited lists are detailed enough that there's effectively nowhere left to change to. In particular, Funded7's "even your own EA gets treated as Group Trading if it correlates too highly with another trader" flatly rules out running the same EA across multiple accounts.

Blueberry, by contrast, moved in the direction of loosening up. The March 12, 2026 revision removed the bans on one-sided bias, grid trading, and all-in trades from Prime, and also abolished the lot-size limit. But old accounts keep the old rules, so check first which version your own account is on.

Among the differences between the challenge and Funded, SuperFunded's and Hantec's news-trading rules kicking in only after you pass is the one with the most practical impact. A method that got you through the evaluation becomes a rules violation the instant you move to Funded.

Most firms with news restrictions treat closing as a violation too. Because SL and TP orders sit on the broker's side, without a mechanism to close out before the window, you can't stop them yourself. This is the one thing you should always confirm before buying.

Also note that FundedElite and TradingCult explicitly ban account rolling. If your plan is to buy and cycle through many challenges, either rule these two firms out from the start or confirm with them beforehand.
