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 most common concern people raise before joining an automated trading service is straightforward: what happens to my money, and can I get it back whenever I want? That objection is entirely reasonable, and it is the one this page addresses directly. Your funds never sit in a QuantStone account. They sit in your own account at Startrader, a regulated broker and QuantStone's partner. You can request a withdrawal at any time, without asking QuantStone for permission, because QuantStone never holds your capital in the first place.

Three things you can verify without taking our word for it: the track record of each algorithm is certified and viewable in real time; the account you open is in your name at a regulated broker; and our commission is charged only when profits are generated, never as a flat subscription. The mechanics of each point are explained below.

What QuantStone Is, and What It Is Not

QuantStone is a provider of two automated trading algorithms, built as MetaTrader Expert Advisors, that run on a virtual private server (VPS) supplied through Startrader. QuantStone is not a broker, not a fund manager, not a signal group and not a wallet or custody provider. The company does not accept deposits, does not pool client money and does not make trading decisions on your behalf in a discretionary sense. The algorithms follow fixed, pre-programmed rules.

If you want to understand what an Expert Advisor is technically before going further, the guide on what an Expert Advisor is in MetaTrader explains the mechanics in plain terms.

How the Withdrawal Process Actually Works

Because your capital stays in your own Startrader account throughout, the withdrawal process is governed by Startrader's standard procedures, not by QuantStone. This distinction matters. QuantStone has no role in approving, delaying or releasing a withdrawal. The steps below reflect what the process looks like in practice.

Step 1: Log in to your Startrader client portal

All account management, including withdrawals, is handled directly through Startrader's portal. You access it with your own credentials. QuantStone does not have login access to your account.

Step 2: Submit a withdrawal request

You choose the amount and method. Startrader supports several withdrawal options. Processing times and available methods depend on Startrader's own policies and your country of residence. These are broker-side variables that QuantStone cannot control or guarantee. Check Startrader's documentation for the current list of supported methods and typical processing durations.

Step 3: The algorithm pauses or continues, as you instruct

You can withdraw part of your balance while leaving the rest to continue trading, or you can withdraw the full amount and effectively close your participation. You do not need to notify QuantStone before doing either. If you reduce your balance below the minimum deposit for the algorithm you are using (350 EUR per algorithm), the algorithm will have insufficient margin to open new positions. That is a practical consequence to be aware of, not a restriction imposed by QuantStone.

What counts as profit for the commission calculation?

QuantStone charges a 20% commission on net profits generated during the calendar month, settled at month end. If the month closes flat or negative, no commission is charged. There is no subscription, no management fee and no charge for setup. The commission is deducted before you receive your month-end statement, meaning the figure you see in your account already reflects QuantStone's share. You withdraw what remains, in full, at any time.

The Two Algorithms and Their Minimum Deposits

QuantStone currently runs two algorithms. Both require a minimum deposit of 350 EUR per account. Running both on separate accounts, as QuantStone recommends, means a combined minimum of 700 EUR. That separation is deliberate: it allows each algorithm's performance and commission to be tracked independently, and it spreads exposure across different instruments and trading styles.

AlgorithmProfileInstrumentsMinimum depositHistorical monthly range (not guaranteed)
SENTINELAggressiveUSDCAD, GBPUSD350 EUR50% to 180% per month, past performance is not indicative of future results
PREDATORModerateXAUUSD (gold)350 EUR20% to 30% per month, past performance is not indicative of future results

Those historical ranges are drawn from the certified track record. They describe what the algorithms have done in the past. They say nothing about what they will do next month. A month of losses is possible, and has occurred. That is addressed in the risk section below.

What You Can Verify Independently

QuantStone publishes a certified track record for both algorithms that can be checked in real time. You do not need to trust a screenshot or a PDF that could have been altered. The page on Forex EAs with a verified track record explains what certification means and how to read it. If the live figures do not match what was described to you, that is a clear signal to walk away.

Beyond the track record, the regulatory status of Startrader is independently verifiable through the relevant licensing authority. QuantStone encourages you to do that check before depositing anything.

For context on how these systems operate technically, the overview of how automated forex trading robots work gives a clear picture of what the algorithm is doing and why it behaves the way it does in different market conditions.

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 Is Not For

This section is written without softening, because getting this wrong costs real money.

  • Anyone depositing money they need to live on. Forex trading with leverage can produce a total loss of the deposited capital. If you need this money for rent, food or emergency reserves, do not deposit it.
  • Anyone who cannot tolerate a losing month. Both algorithms have produced losing months. A 20% commission on profits also means a zero-commission month that is still a month of negative trading results. That outcome is realistic and has happened.
  • Anyone expecting guaranteed or predictable income. QuantStone guarantees no return whatsoever. The historical figures are not a forecast. They are a record of past behaviour under past market conditions.
  • Anyone who wants to deposit and never look at their account again. You are responsible for your own account at Startrader. QuantStone does not monitor your account on your behalf in a custodial sense. You should check your account regularly and understand what you are looking at.
  • Anyone below the minimum deposit threshold. The algorithms require 350 EUR per account to function with adequate margin. Depositing less does not create a smaller version of the strategy; it creates a margin problem.
  • Residents of the United States. QuantStone is not available to US residents. Retail forex trading is heavily restricted under CFTC and NFA rules, and Startrader does not serve US clients. This is a firm exclusion, not a grey area.
  • Anyone looking for investment advice. QuantStone does not provide it. Nothing on this page or on the Telegram channel constitutes a recommendation to buy or sell any financial instrument.

Honest Risks and Limits

Automated algorithms trade according to rules. Those rules were built and tested under specific historical market conditions. When market conditions change significantly, an algorithm that performed well in the past can perform poorly or generate sustained losses. There is no mechanism that prevents this. Drawdown periods, where the account balance falls below its recent peak, are a normal part of any algorithmic trading strategy and can last for weeks or longer.

Leverage amplifies both gains and losses. A position that moves against the algorithm can produce a loss that is a multiple of the margin committed to it. At extreme levels of adverse movement, a margin call is possible. QuantStone's commission structure means the company has no financial interest in encouraging you to take more risk than the algorithm's design specifies, but the underlying market risk remains yours.

More than 500 investors currently use QuantStone. Their individual results vary depending on when they joined, which algorithm they use, their account size and the market conditions during their active period. No aggregate figure for those results is published here, because no such figure would be representative of your individual outcome.

How to Get in Touch and What Happens Next

All onboarding and support happens through the QuantStone Telegram channel. The setup process takes roughly 15 minutes: you open an account at Startrader, connect the algorithm via the VPS that Startrader provides, and the system begins trading without requiring your computer to remain switched on.

Join the channel at the QuantStone Telegram channel to ask questions, review the live track record link and go through the setup steps. There is no sales call and no pressure to deposit before you are ready. The verified track record is available before you commit anything.

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.
