This page is published by QuantStone. It is not an independent review, so treat it as the company's own account and verify the checkable facts yourself.
The short answer to how much QuantStone costs: there is no subscription fee, no monthly charge, and no setup cost. QuantStone charges a 20% commission on the profits its algorithms generate, settled at the end of each month. If the algorithms produce no profit in a given month, you pay nothing. You can verify that structure yourself before committing a single euro, because the track record is certified and visible in real time, your funds sit in your own account at a regulated broker, and the commission is only ever charged on actual gains.
If you want the detail behind those three sentences, the rest of this page explains exactly how the model works, what it costs in practice, what can go wrong, and who this service is honestly not suitable for.
What QuantStone is, and what it is not
QuantStone builds and operates two automated trading algorithms, known as Expert Advisors, that run on the MetaTrader platform. Both were developed in house and both have a certified performance history that you can check in real time. If you are unfamiliar with how this type of software functions, the guide on what an Expert Advisor is in MetaTrader covers the mechanics in plain terms.
QuantStone is not a broker. It does not hold your money, pool your capital with other clients, or operate as a fund. It is not a signal group where you manually copy trades. It is a technology provider that attaches its algorithms to your own brokerage account. The distinction matters: at no point does QuantStone take custody of your funds.
More than 500 investors currently use the service. The partner broker is Startrader, a regulated firm. Your account is yours, the capital is yours, and you can withdraw at any time without asking QuantStone for permission.
How the service works in practice
The setup process is straightforward and takes roughly 15 minutes. You choose one or both algorithms, open a live account at Startrader, deposit the minimum required amount, and connect the algorithm to your account. A VPS (a remote server that keeps the software running continuously) is provided through Startrader, so you do not need to leave a computer switched on around the clock.
Once the algorithm is live, it trades automatically according to its own rules. You do not need to monitor every position or make manual decisions. That said, you remain responsible for your account. You should check it periodically, understand what you are looking at, and be prepared for months where results are negative. The article on how automated forex trading robots work is a useful primer if you want to understand what is happening under the hood.
If you plan to run both algorithms, QuantStone recommends opening a separate account for each one. This keeps the risk profiles distinct and makes the commission calculation straightforward.
The exact cost of using QuantStone
The commercial terms are simple enough to state in a table.
| Item | Cost |
|---|---|
| Subscription or monthly fee | None |
| Setup fee | None |
| Commission on losing months | None |
| Commission on profitable months | 20% of the profit generated that month |
| Minimum deposit per algorithm | 350 EUR |
The commission is settled at the end of each calendar month. If February produces a gain of 400 EUR on your account, QuantStone's fee is 80 EUR. If March produces a loss, the fee is zero. There is no subscription running in the background regardless of results.
The two algorithms and their profiles
There are currently two algorithms available. Both require a minimum deposit of 350 EUR per account.
- SENTINEL is the more aggressive of the two. It trades USDCAD and GBPUSD. Historical monthly performance has ranged from 50% to 180%, though past performance is not indicative of future results and those figures carry no implication about what you should expect going forward.
- PREDATOR is a more moderate profile, specialised in gold (XAUUSD). Historical monthly performance has ranged from 20% to 30%. Again, past performance is not indicative of future results, and no return is guaranteed under any circumstances.

What you can verify independently
QuantStone encourages you to check the following before making any decision, and none of these require taking the company's word for anything.
- The track record. Both algorithms have a certified performance history that is visible in real time. You can review the actual trading history, not a curated summary.
- Where your money sits. Your funds are held in your own account at Startrader, a regulated broker. You have full ownership and can withdraw at any time. QuantStone does not have access to withdraw your capital.
- The commission model. The 20% on profits only structure means there is no fee unless the algorithm makes money for you. You can confirm this from the account statements generated by Startrader.
The broader question of how to evaluate an automated trading service before committing capital is covered in the guide to the best automated forex trading systems for beginners in 2026, which is worth reading before you decide.

Trading involves risk and you can lose some or all of your invested capital. Past performance is not indicative of future results. QuantStone is not available to residents of the United States.
Who this service is not for
This section is written to be direct, not to discourage participation for the sake of it, but because the wrong fit causes real financial harm.
- Anyone depositing money they need to live on. Forex trading carries genuine risk of loss. The minimum deposit of 350 EUR is a floor, not a guarantee that you will not lose it. Do not deposit rent money, emergency savings, or funds you cannot afford to lose entirely.
- Anyone who cannot tolerate a losing month. Both algorithms will produce losing months. That is not a remote possibility but a normal feature of algorithmic trading. If a negative month would cause you serious financial or psychological distress, this is not the right service.
- Anyone expecting a guaranteed or predictable income. QuantStone does not guarantee any return. The historical figures quoted for SENTINEL and PREDATOR are historical records, not forecasts or promises. Monthly results vary significantly and can be negative.
- Anyone planning to set it up and never look again. You remain responsible for your own account. The algorithm handles the trading decisions, but you should check your account regularly, understand what is happening, and be capable of withdrawing or stopping the algorithm if your circumstances change.
- Anyone below the minimum deposit. The minimum is 350 EUR per algorithm. There is no lower entry point and no payment plan.
- Residents of the United States. QuantStone is not available to US residents. US retail forex is heavily restricted under CFTC and NFA rules, and the partner broker Startrader does not serve US clients. If you are based in the United States, this service is not an option for you.
The article on automated trading mistakes beginners make covers several of these points from a practical angle and is worth reading even if you have prior trading experience.
The honest risks and limits
Algorithmic trading does not eliminate risk. It replaces manual decision making with rule-based decision making, but the underlying market risk remains. Here is what that means for QuantStone specifically.
- Past performance is not indicative of future results. The historical ranges published for SENTINEL and PREDATOR describe what has happened, not what will happen. No trading strategy has ever worked in every market condition.
- Both algorithms can go through extended losing periods. A single bad month is possible. Multiple consecutive losing months are also possible. Leverage amplifies both gains and losses, and the forex and gold markets can move in ways that no model fully anticipates.
- You are responsible for your own capital. QuantStone operates the algorithms, but the account belongs to you. If you choose to add funds, withdraw, or stop the service, that decision is yours to make.
- QuantStone does not provide investment advice. Nothing on this page or elsewhere on the site constitutes a personalised recommendation to trade any financial instrument.
How to get in touch and what happens next
If you want to start, ask a question, or simply see the verified track record before committing, the right place is the QuantStone Telegram channel at t.me/+ZJPJDABDBZ43MGRk. That is where onboarding happens and where you can ask anything directly.
There is no sales pressure and no time-limited offer. If the model suits your situation after reviewing the facts, the setup takes roughly 15 minutes. If it does not suit your situation, the information on this page should have made that clear.
Risk warning
Trading involves risk and you can lose some or all of your invested capital. Past performance is not indicative of future results. Only trade with money you can afford to lose. QuantStone does not provide investment advice and nothing here is a recommendation to buy or sell any financial instrument.
