Challenge Distillation: Run Multiple Accounts on Unrelated Waves, and Only Advance the Survivors | Same Expected Value, but the Odds of Actually Winning Went from 13% to 81%
Until May, I mirrored the same trades across every account. Now I run multiple challenges in parallel on unrelated waves, and only advance the ones that survive. I call this "challenge distillation." A 40,000-run Monte Carlo test showed distillation doesn't add a single yen of expected value. What it adds is the probability of actually capturing that expected value — from 13.0% to 81.1%, even at zero edge. What matters isn't the number of accounts but the correlation between them: at correlation 0.8, risk only ever falls to 0.894 no matter how many you stack. Covers how much each way of splitting waves (instrument, day of week, time of day, SL/TP) actually helps, why even a funded account should be blown up once you've withdrawn from it, and where this differs from the banned practice of cross-account hedging. Calculated using real list prices from Fintokei, FTMO, and FundedNext. In September 2026 I also verified this on real data (5 strategies × 8 instruments = 40 waves, 2010–2026): running the same wave on every account leaves the total-wipeout rate stuck at 58.4%, while splitting into 10 waves drops it to 1.8%.

Is a Challenge "Expected-Value Positive Just by Buying It"? I Built a Coin-Toss EA and Backtested It 16 Times [Analysis]
Placing SL/TP at spread x 40 makes the cost ratio independent of the currency pair. Verified with an exact solution plus 24 real EA runs, a single challenge's expected value comes out to +¥119,000 against a ¥108,800 fee (95% CI +¥18,000 to +¥381,000). Raising the number of daily attempts up to the daily loss limit shrinks the time to resolution from 139 days to 7 days without lowering the pass rate, and across multiple accounts, simply using a different random seed per account shifts the probability of finishing positive from 56% to 98%. The one remaining hole is a stop-loss getting jumped by a gap.
What Dan Cheung Means by "Rotation": It's Not About Doing More Trades — It's About Containing Losses to One Account
We looked into Dan Cheung's (London-based) account rotation, a term that comes up a lot in prop trading circles, based on his own public statements. It boils down to three lines: touch only one account at a time, close that account and move to the next once you hit your daily profit target or your stop, and never chase a losing account. People often mistake it for a way to trade more, but the real point is containing losses to a single account. We then checked whether this actually holds up under the terms of firms available from Japan, across four axes: consistency rules, minimum trading days, allocation caps, and multi-account clauses.

Try to run the same strategy across multiple accounts and you hit a total-allocation cap. The range spans 14x, from E8 Markets' $4.25M down to FundedNext and PipFarm's $300K. FTMO $400K, FundedNext $300K, Funding Pips $400K, SuperFunded $900K, Hantec $400K, Fundora ¥60M — the range is wide. Even more important is whether challenge-stage accounts eat into that cap, which runs in opposite directions depending on the firm. The5ers requires a different trading method per account, which rules out running the same EA across multiple accounts there.
Multiple Prop Accounts: 'Rotation Diversification' Beats 'Full Mirroring' | Correlation Risk and the Rulebook Trap
Mirroring the same EA across every account feels like diversification, but it actually concentrates correlation risk by a multiple of your account count. This article explains, with concrete examples, why a rotation-based approach — fixed lot size, rotating accounts on drawdown — lowers your risk of ruin, plus the copy-trading rule traps and detection risks involved.

Which Firm for Running Multiple Challenges at Once? Picking a Firm by Swing vs. Day Trading [August 2026]
When running multiple challenges at the same time, the criteria for picking a firm differ from running a single account. This piece sorts 16 firms along 3 axes — whether copying between your own accounts within the same firm is allowed, whether a violation on one account spreads to your others, and the cap on total capital — and gives separate recommendations for swing trading and day trading.

Can You Change Strategy Mid-Way? | I Checked 20 Firms' Consistency Rules and Found They Go in Opposite Directions [September 2026]
FundedNext explicitly states you must 'maintain the same strategy through your challenge and Funded account,' banning switching from an EA that passed the challenge to manual trading. Fintokei, meanwhile, states plainly it has no consistency rule and won't add one retroactively. Even within one firm, Hantec's Enhanced has no restriction while EnhancedX caps you at 35% — opposite treatment. Here's what to check before changing your method, across 20 firms.

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]
TradingCult bans EA and bot use outright, and a violation is a hard breach. The firm and FundedElite also explicitly ban 'account rolling.' At Funded7, even your own EA gets you disqualified for Group Trading if its results correlate too closely with another trader's. SuperFunded allows news trading freely during the evaluation but bans it within ±10 minutes only at the Funded stage, and FundedElite's strategy risk limit only applies at the funded stage — this article rounds up 9 firms whose rules change between the challenge and funded stages, based on each firm's official FAQ.
When Should You Change Your Prop Account Settings? Don't Touch It During Evaluation — Always Change It the Moment You Get Funded
When a challenge isn't going the way you'd hoped, you want to raise your lot size. You want to change your trading hours. But that judgment call has no statistical basis. Telling a 40% pass-rate method apart from a 25% one needs 150 accounts per method, and most people only have one or two. Meanwhile, the moment you reach a funded account, rules that didn't exist during evaluation kick in all at once — Hola Prime caps risk per trade at 2%, Hantec treats the 3 minutes around a news release as a violation even to close a position. These are cases where you must change something. We sorted out what to keep fixed, what to change, and how to treat an account that's already deep in drawdown, using 40,000 Monte Carlo runs. As of September 18, 2026.

The Same Strategy Can Take 3x Longer Depending on Where You Run It: Testing 8 Firms' Rules Against a Mechanical Strategy [Analysis]
Profit targets and max DD line up almost identically across firms, yet running the same strategy through their rules stretches the cycle time from 17.2 days to 59.6 days — a 3.5x spread. The cause is the '1% risk per trade' rule. Pass rates barely differ (33.7–38.7%), while firms with a 10% Phase 1 target are 5 points worse off at the first stage, and a 60% profit split cuts expected funded-stage income by 40%. Also checks Hantec's 3-minute rule, which is actually a ratio condition — 'net profit from trades closed under 3 minutes is 30% or more of total' — against 3,826 real trades' holding-time distribution.

A Funded7 payout request came back DELAYED for failing "Rule 1 (Consistency): Position Sizing" R1A. We break down the official FAQ's allowable threshold — MIN(median×2.5, Q3+1.5×IQR) — using real figures from a review email sent to this site's owner (median ¥1,240,946, IQR ¥17,094, threshold ¥1,274,058, largest position ¥1,294,723). Covers why keeping your lot size too consistent shrinks the threshold, why a fixed-lot BTC EA gets caught, how it differs from Rule 2/Rule 3, why profit isn't confiscated, and how to think about passing on the next review.

What Percentage of Prop Phase 1 Would a Coin Toss Pass? The Exact-Solution Answer Comes Out Above 50% [Analysis]
An exact calculation of the Phase 1 pass rate for a prop challenge using nothing but a ±¥200,000 coin toss. With zero fees, an 8% target / 10% max DD setup passes 55.6% of the time, and FTMO comes out at exactly 50.0%. With a 5% fee it drops to 43.2%, and it sinks into the 8% range for 1-step plans with a 3% daily DD. Compared with real-world pass rates of 5-14%, the average trader is losing to a coin toss.
