Rigorous research. Systematic execution.
The Portfolio runs four independently researched strategy cells across USDJPY, DE40, UK100 and NAS100 on your own MT5 terminal. Every figure we publish puts the drawdown next to the return.
Trained and tested on ten years of walk-forward data, 2016 to 2026. The figures above are the most recent 24 months of that test.
Net of spread,commission & slippage
Return and drawdown, given equal space.
Results are in R, where 1R is the amount risked on one trade. That keeps them independent of account size: multiply by your risk per trade to get money. Move across the chart to read any point.
Hypothetical: most recent 24 months of the 10-year walk-forward backtest, net of costs. The chart plots month-end values, so its drawdown panel is shallower than the −16.4R maximum drawdown, which is measured trade by trade.
Backtested results are hypothetical. They were produced with the benefit of hindsight, do not reflect real orders or real fills, and cannot account for every market condition. Live results will be published here, unedited, from the first trade.
Four cells, run as one.
The cells are not sold individually because none is strong enough alone. Together they spread risk across markets, sessions and trade styles, which is what produces the combined record above.
Each cell trades its own part of the day, so the Portfolio is rarely exposed to one market at one moment. Entry rules and parameters stay private; everything else is published.
Reversal
Trades the London session, fading short-term extremes once the market shows it has turned.
Mean reversion
Buys pullbacks in European indices during cash hours, expecting price to return towards its recent average.
Momentum
Follows strong moves in the DAX into the US open, and always exits by the European cash close.
Breakout
Buys the Nasdaq when it breaks out on high-volatility days, holding for up to a few days.

What the licence does
6 months of research and development, from a developer with 6+ years in financial markets.
A backtest is only as good as the ways it was tested, so this is how we tried to break it. Every cell was developed on ten years of data with a rolling walk-forward: fit on one window, test on the next unseen window, step forward and repeat. Only the test windows count towards the record.
No look-ahead bias
Signals only use data that existed at the moment of the decision. Bars are processed in order, as they would arrive live.
In- and out-of-sample
Rules were fitted on one slice of history and judged on data they had never seen.
Walk-forward testing
The fit-then-test window rolls through ten years, so the reported results come from unseen data.
Monte Carlo
Trade order is reshuffled thousands of times to show how bad drawdowns could plausibly get, beyond the one path history gave us.
Modelled costs
Spread, commission and slippage are applied to every trade in the headline numbers.
Live record
Once trading starts, live results sit beside the backtest so you can see how closely they track.
Does it make sense for your account?
Put in your own numbers. The simulator replays a year of trades 2,000 times and shows what you'd expect to keep after the software fee, and how wide the range of outcomes is.
Marginal. The fee would take about 28% of expected profit; a larger account makes more sense. In a bad year, expect a drawdown of around 19.8% of the account.
Simple model: fixed risk on starting balance, no compounding, 2,000 simulated years drawn from the assumptions. Expected values are averages, not forecasts.
Could you run this?
Six questions. Systematic trading is mostly about sitting through losing stretches without touching anything, so we'd rather you find out now.
Twenty seats. One price, kept by founders.
- 14-day free trial on a broker demo account; cancel before day 14 and you pay nothing
- All four cells on one MT5 account
- Founding price locked for as long as you stay subscribed; later seats will cost more
- Live Telegram log of every trade
- Live results published for every subscriber to check
- Cancel any time; the licence runs to the end of the period you have paid for

contact@bayesiansystems.ioQuestions people ask first.
Is this a signal service?
No. You license software that runs on your own MT5 terminal and trades your own account using your settings. Nothing is broadcast from a central server.
Can I use it on a prop firm account?
Only at firms whose rules allow automated trading with third-party EAs. Rules differ and change, so check your firm's terms before you attach it. Some firms also restrict risk per trade or have consistency rules; enter those in the calculator.
What does R mean?
R is one unit of risk: the amount you lose if a trade hits its stop. At 0.5% risk on a $50,000 account, 1R is $250, so +44.2R would be about $11,050.
How bad can the drawdown get?
The worst drawdown in the last 24 months was −16.4R, and −34.6R across the full ten years. Monte Carlo testing suggests a future drawdown could be deeper, so size your risk so you could sit through that without switching it off.
Do I need a VPS?
The Portfolio only trades while MT5 is running and connected, so a Windows VPS close to your broker's server is strongly recommended.
Can I run it on more than one account?
Each licence key runs on one MT5 account. For several accounts, use a master account that manages them.
How does the free trial work?
You get 14 days of full access on a broker demo account, so you can watch it trade without risking money. Trials can't run on live or prop-firm accounts, and each MT5 account can trial once. We remind you by email 2 days before it ends; cancel any time before then and you pay nothing. If you continue, the licence moves once, automatically, to the first live account you run it on.
Which plan should I choose?
Monthly is $795, quarterly $1,995 and annual $5,995. Systematic strategies have flat and losing stretches that can last a few months, so a longer plan lets you judge the software over a fairer sample. All plans keep the founding price for as long as you stay subscribed.
What happens if I cancel?
The licence stays active to the end of your paid period. After that the software stops opening new trades. It never closes your open positions on its own when the licence ends.
Can I see the exact trading rules?
No. Entry rules and parameters stay private, so the edge isn't copied away. What is published: the markets, sessions, trade style and direction of each cell, the research method, and full results including every drawdown.
Is it available in my country?
In most countries, yes. It is not offered where local law prohibits selling or using automated trading software, or to sanctioned persons or countries. You are responsible for confirming it is lawful where you live, and that your broker or prop firm allows automated trading.
Is MT4 supported?
Not at launch. MT5 only.
Licence, terms and risk.
Plain-language versions of the documents that govern your subscription. Bracketed details are completed before launch.
Risk disclosure
Trading carries a high risk of loss. Forex, CFDs and futures are leveraged products. Small market moves can cause large losses, and with some brokers you can lose more than you deposit. Most retail traders who trade leveraged products lose money. Only trade with money you can afford to lose.
Hypothetical performance has limitations. Results shown on this site come from backtesting and simulation unless clearly labelled as live. Hypothetical results are prepared with the benefit of hindsight, do not represent real trading, and do not involve financial risk. They cannot fully reflect slippage, liquidity, spreads at the time, execution delays, or the pressure of trading real money. No representation is made that any account will or is likely to achieve results similar to those shown. Actual results can differ materially, including larger drawdowns.
Past performance does not guarantee future results, whether the performance is real or simulated. Strategies that worked historically can stop working.
Technology risk. Automated trading depends on your terminal, VPS, internet connection, broker and our licence server. Outages, latency, data errors or software faults can cause missed, delayed or unintended trades.
Prop firm accounts. Each firm sets its own rules on automated trading, risk and consistency. The software does not guarantee passing any evaluation or keeping any funded account. You are responsible for checking and following your firm's rules.
Not advice. Nothing on this site is investment, financial, legal or tax advice, or a personal recommendation. Consider your own circumstances and, if unsure, speak to an independent adviser.
End User Licence Agreement
1. What you are licensing. The Portfolio is automated trading software for MetaTrader 5. When running, it analyses market data and opens, manages and closes trades on the account it is attached to, according to built-in strategy rules. You control the risk per trade, which strategy cells are active, trade-management options and daily trade limits, and you decide whether and where to run it.
2. Licence grant. While your subscription is active and paid, we grant you a personal, non-exclusive, non-transferable, revocable licence to run the software (a Windows application) on the single MT5 account number registered to your licence key. Running more accounts requires additional licences.
3. Restrictions. You may not copy, share, resell, sublicense, rent, decompile, reverse-engineer, or attempt to extract the strategy logic from the software, or bypass the licence check, except where the law expressly allows it.
4. No advice or management. We are a software provider. We do not give investment advice or personal recommendations, manage your account, hold your money, or trade on your behalf. Every trade the software places is on an account you control, under settings you choose.
5. Your responsibilities. You are responsible for: choosing an appropriate risk level; keeping your terminal, VPS and connection running; monitoring your account; confirming that your broker or prop firm permits automated trading; and complying with the laws that apply to you.
6. No guarantee of results. We do not guarantee any profit, performance, or that the software will pass or keep any prop firm account. Published results, including backtests, are not a promise of future returns.
7. Licence checks and ending your licence. The software checks its licence with our server. If the licence expires, is cancelled or cannot be verified, the software stops opening new trades. It does not close your open positions; managing them becomes your responsibility.
8. Updates. We may release updates that change or improve the software, including its strategy rules, and will tell you about material changes. Some updates may be required to keep the licence working.
9. Ownership. The software and its strategies remain our intellectual property. You receive a licence to use it, not ownership.
10. Limitation of liability. To the fullest extent the law allows, we are not liable for trading losses, lost profits, prop firm breaches or account losses, or losses caused by outages, latency, broker issues or software faults. Our total liability to you is limited to the subscription fees you paid in the three months before the claim. Nothing in this agreement limits liability that cannot legally be limited, including for fraud, or for death or personal injury caused by negligence.
11. Free trial. New subscribers may get a 14-day free trial. During the trial the software runs only on broker demo accounts, not live or prop-firm accounts, and each MT5 account can trial once. We remind you by email at least 2 days before the trial ends. Unless you cancel before it ends, your chosen plan starts and you are charged. After the first payment the licence moves once, automatically, to the first live MT5 account the software runs on.
12. Subscription and cancellation. The subscription renews at the end of each billing period (monthly, quarterly or annual, as chosen at checkout) until cancelled. You can cancel at any time; cancellation stops future payments and the licence stays active to the end of the period you have paid for.
13. Right to cancel (UK and EU consumers). Consumers in the UK and EU normally have 14 days to cancel a digital purchase. By ticking the box at checkout, you ask us to give you access straight away and acknowledge that you lose that right once the download or licence activation begins. Your other statutory rights, including for faulty digital content, are not affected.
14. Where the software is offered. The software is not offered to anyone in a country where its sale or use is prohibited, or to persons or countries subject to US, UK or EU sanctions. You confirm that using it is lawful where you live.
15. Governing law. This agreement is governed by the laws of England and Wales, and its courts have jurisdiction. If you are a consumer, you also keep any protections given to you by the mandatory laws of the country where you live, and you may bring claims in your local courts where the law allows.
16. Changes. We may update this agreement and will give notice of material changes before they apply to your next billing period.
