BIASMACHINE essentials
What is BIASMACHINE?
A market-statistics platform for traders: it shows on the chart how often similar events on the chosen asset ended in continuation or reversal and lets you test hypotheses on history in a free tester. It is not a broker, not signals and not a course.
How the calculations work is on the How it is computed page.
Is this a forecast?
No. It is a count of historical frequencies under a stated rule: event, time window, sample, period. The platform does not predict the next price move.
Are these trading signals?
No. Highlights and percentages on the chart describe how rare the current deviation has been historically. The trading decision and the responsibility for it stay with the user.
What is free?
- Tester and trading on history — regular practice attempts
- Deviation quantiles and basic statistics
- CFD 10k and futures-rules 50k challenges (the latter is labelled CME 50k in the interface; the platform is not affiliated with CME)
A free account is required.
What does Pro add and what does it cost?
- Realtime and algo levels for all assets
- Research: scenario studies and the experimental Signal Bar
- Advanced replay: date selection, higher speed, fast-forward and extra history
- Blind mode in the tester
- Other challenge account sizes and prop-firm rules, Funded continuation after a notional payout
- Advanced trade journal and analytics
- Telegram notifications

Where does the data come from and how is it processed?
The basis is second-level price history since 2019–2020 (the start depends on the asset); every series is aligned to New York time with daylight-saving changes handled and checked for gaps. The trading day runs from 18:00 to 18:00 New York time. Details on the How it is computed page.
Which assets are covered?
US100 (Nasdaq 100), US500 (S&P 500), DAX, XAUUSD (gold), EURUSD and GBPUSD. Every study is computed separately for each asset because the same hypothesis yields different frequencies on different assets.
How do I check a number myself?
Every study states its rule, window, sample and period, so the calculation can be repeated on your own data. In the free tester you can test a hypothesis by trading on history. In Research (Pro) every case in the sample opens on the chart with one click.
How is this different from courses and mentoring?
The platform does not teach "the right strategy". It gives a tool: history, frequencies and a tester to check any idea, yours or someone else's. There are no paid courses or mentoring.
How is it different from TradingView Bar Replay, Forex Tester and FX Replay?
Those are trainers for manual trading on history. BIASMACHINE lets you trade on history too, but its focus is different: counting event frequencies under documented rules and showing the statistics right on the chart.
How does the prop-challenge emulation work and is it free?
It is practice on historical data with typical prop-firm rules: profit target, daily loss limit, maximum drawdown, phases. The rules are modelled on the published conditions of firms such as FTMO or Topstep; the platform is not affiliated with those companies.
CFD 10k and futures-rules 50k challenges (labelled CME 50k in the interface) are free after sign-in. Other account sizes, prop-firm rules and Funded continuation after a notional payout are in Pro. No real money is paid out: a challenge payout is notional, inside the practice account.
Can the percentages be read as the probability of making money?
No. A percentage is the share of historical cases under a rule. It is not a win rate and does not guarantee repetition. With a small sample the figure is unreliable, so look at the number of cases.
Who makes BIASMACHINE?
Georg Vahi, Estonia; company ALGOFLOW OÜ (Tallinn), since 2025. YouTube channel "HINN · BIASMACHINE", Telegram channel t.me/BSMCHNS, author contact @GeorgVahi. Company details are on the About page.
Is it safe, is it legit?
The platform takes no money under management and promises no income. What is free and what is paid is on the Access page; Pro is a one-time payment without auto-renewal, and refund rules are in the Terms of Use.
Reviews are written by registered participants after a confirmed notional challenge payout and are published after moderation. Company details are on the About page.
Tester, challenge and account
Is this real-money trading?
Tester and Challenge are historical-data demos. Challenge trades, deposits, fees and payouts are virtual. Passing a phase or receiving a certificate does not provide a real account or funding.
Research and experimental features are research demos. Statistics are static: they describe a historical sample, do not predict markets and guarantee nothing. Purchasing Pro is a separate paid service.
How does Challenge work, and what does PRO add?
BIASMACHINE CFD 10k and CME 50k are free after sign-in. PRO lets you choose other CME/CFD sizes, a prop firm and a program from the catalog.
The selected program rules apply automatically and are fixed when the account is created. Phases, targets, drawdown, position limits, simulated fees and Funded activation appear in the account card and the hints above the chart.
Without PRO, the account ends after its first payout. With active PRO, you can keep trading Funded after payouts until a risk breach. The selected program limits on payout count and amount still apply.
How is an attempt’s volume limit determined?
Challenge position limits depend on the plan: contract count for CME, available margin and leverage for CFD. Exact terms are fixed when the account is created. Account level does not increase the deposit or position limit. Trading settings choose new-order size within the current limit.
Why did an account fail with positive final PnL?
A daily or total drawdown limit may have been breached earlier, including by an open position. A curve based on closed trades may not show that moment. The phase card gives the failure reason.
Later profit does not undo a breach. Risk rules and drawdown calculations depend on the selected plan.
How do trading hours work?
For CME and CFD, choose any hours in New York time or leave the schedule off. With a schedule enabled, new trades and entry-order fills are blocked outside those hours; closing positions and protective exits remain available.
When no positions are open, replay can skip to the selected trading hours. The schedule does not override other account rules.
What is net profit in the public profile?
Virtual payouts + fee refunds − fees for Challenge accounts included in your public profile. It is neither the sum of trade PnL nor the deposit size.
The CME/CFD filter changes the displayed sample. Profit rewards use the combined total of both families without a filter.
How do I earn a private group invitation?
Every $50,000 of net Challenge v2 profit in your public profile earns a new unique link: $50,000 earns the first, $100,000 the second, $150,000 the third. CME and CFD net profit count together.
Each link allows one person to join and lasts 7 days from creation. It arrives in your account inbox and a popup notification.
Each threshold is rewarded once. Falling from $50,000 to $49,000 and returning to $50,000 does not earn another link. Using a link or letting it expire does not reset the threshold. Crossing several new thresholds at once earns one link for each.
Where can I see phase trades and replays?
Select a phase on the Challenge card. Its curve starts at the nominal deposit and changes with closed trades. Public replay links appear below the chart.
Consecutive phase days for one instrument share a replay; gaps split them. A closed phase journal is published automatically and cannot be hidden.
How much history does Tester load?
Tester and Challenge first load two days to the left and the current replay day. Once the chart appears, another two days load to the left in the background.
Future candles of the current day stay buffered until replay reveals them. The current candle sits in the centre, with history to its left.
What is in Research, and who can access it?
Research shows how price behaved in past situations: after level sweeps, pullbacks, continuations and Algo events. Each study describes its sample, method and limitations.
Deviation quantiles and simple statistics require sign-in, without Pro. Other research and experimental features require Pro.
The experimental section adds Signal Bar to the Realtime chart. Tester and Challenge do not use it. Lessons are currently admin-only.
How do I leave a review?
Each confirmed simulated Challenge payout lets you submit one review. Its certificate is attached automatically. Reviews appear after moderation.
When does the referral programme unlock?
Once your Challenge balance — payouts and refunded fees minus fees — reaches +$50,000 while Pro is active. Your first promo code then appears in your account by itself, with the terms.
Where are my reward link and notifications?
Open your account inbox. Dismissing a popup does not delete its message. Your profit invitation stays there with its expiry time.
What do MFE and MAE mean?
MFE is the largest favourable move while a position was open. MAE is the largest adverse move. They describe the price path, not necessarily realised profit or loss.
What does Capture measure?
The share of the available favourable move you realised: PnL / MFE × 100%. It is undefined when MFE is zero. A high value for one trade does not guarantee a robust strategy.
What are quantiles?
A quantile is a distribution boundary: p60 means 60% of sample observations were no higher than that value. Entry and exit quantiles describe price relative to the selected historical distribution. They do not predict the next candle.
