Rule-based trading software
Maridoship: you set the rules, your broker holds the money
Maridoship rule-based trading software places orders only inside limits you set: the markets, the share of your account at risk on each trade, and where each trade stops. The money stays with a licensed broker, never with us.

What Maridoship rule-based trading software is, and is not
Quantum Software Technologies Ltd, the company behind Maridoship, has the word “quantum” in its legal name. The software does not use quantum computing. It is plain automated trading software that follows the rules you write. Read the company facts for the rest.

It is
- software that follows your rules
- a way to size every trade from your own risk figure
- free to join, with trading costs paid to the broker
It is not
- a broker, bank or adviser
- a holder of your money
- a forecast, or a promise of any result

Rules in, orders out
How it works: set trading rules, get orders inside them
You enter the rules once: which markets, how much of your account to risk on each trade, and where the stop and the take-profit sit. The software reads order-book depth with ordinary statistics and works out a position size that fits your rules. It sends an order to your broker only if the order fits.
The drawing shows the idea. It is illustrative, not live data.
Illustrative, not live data, not a prediction
- Rule risk 2% of balance, stop 40 points away
- Size worked out from those two numbers
- Order sent to your broker, inside the rule

Said plainly
How you can lose money, and why big losses are hard to undo
You can lose all of your deposit. Spreads cost you on every trade, gearing magnifies losses, and a price can gap past your stop. A rule that fitted past prices can fail on new ones. The chart shows the arithmetic: the bigger the loss, the steeper the climb back. The Risk Disclosure has the full list.

Educational arithmetic, not a forecast
Lose 20% and 80 of every 100 is left. To get back to 100 you need a gain of 25% on what is left.
And how fast a run of losses adds up
The same arithmetic from the other side: how much is left after a run of losing trades, at three different sizes of risk.
Educational arithmetic, not a forecast
- 1% risk per trade95.1
- 2% risk per trade90.4
- 5% risk per trade77.4
Left of every 100, after the losses shown. Smaller risk per trade leaves room to be wrong many times. It is arithmetic, not a prediction.

Sixteen questions
Questions, answered plainly
16 of 16 questions shown
What is Maridoship?
Maridoship is rule-based trading software. You choose the markets, how much of your account to risk on each trade (1% to 5%) and where each trade should stop or close. The software places orders inside those limits through an executing broker. It is not a broker, a bank or an adviser, and it does not predict prices.
How does it work?
You enter your rules once. The software reads order-book depth with ordinary statistics, works out a position size that fits your rules and sends an order to your broker only if the order fits. A Halt Execution button stops new orders in one click. Positions that are already open stay with your broker.
Who holds my money?
The executing broker for your country holds your money in a client account, and executes and clears your trades. Maridoship holds none of it.
What does it cost?
The software and joining cost £0. You pay trading costs to the broker, mainly the spread on each trade, plus any fees your broker or bank charges. Maridoship is paid by brokers through rebates and referral fees, which does not add to the cost of the software.
What is the minimum deposit?
Opening an account needs a deposit from $250 AUD · £250 GBP · €250 EUR · $250 CAD · $250 NZD · $250 SGD. It is your own money and it is at risk.
How do withdrawals work?
You can ask for any amount up to your balance at any time. Maridoship applies no lock-up, no holdback and no withdrawal fee. The broker reviews requests within 24 business hours and money then clears in 1 to 3 business days. These are usual service levels, not promises, and the broker's terms are the ones that bind.
Can I lose more than I deposit?
That depends on your broker's protection against negative balances, so ask before you deposit. What is certain is that you can lose all the money you deposit. Prices can gap past a stop-loss, and your order can then fill far from the level you chose.
How can I lose money?
Through spreads on every trade, rules that fit past prices and fail on new ones, gearing that magnifies losses, gaps past your stop, outages, and your own choices. The recovery chart on this page shows why big losses are hard to undo: a 50% loss needs a 100% gain to get back to even.
Is my data secure?
This site uses TLS 1.3, and form submissions are rate-limited and checked on our server. Records are kept outside the public web folder. We ask only for your name, email and phone number, never for passwords, bank details or identity documents. No system is perfectly secure, which is why we collect so little.
What about tax?
We cannot give tax advice. Tax depends on your country and your circumstances, and gains and losses on CFDs may be treated differently from other investments. Speak to a qualified tax adviser.
How are you paid?
Brokers pay Maridoship rebates and referral fees for the clients we introduce. That does not add to the cost of the software, which is £0. It does mean we earn when someone opens a live account, which is why every page carries an advertising disclosure and why our review is not independent.
Is it a scam? Is it legitimate?
We cannot prove a negative, and we are the seller, so please check rather than trust. Maridoship is a trading name of Quantum Software Technologies Ltd, company number 14209581 in England and Wales. Look it up on Companies House and check that the name and number match. Our platform review lists what else you can check yourself.
Do I need experience?
No, but you do need to understand what a stop-loss, a spread and gearing are before you trade, because the software only follows the rules you set. The Risk Disclosure explains them in plain words. If you do not understand CFDs, do not deposit.
How do I log in, and how do I spot fake sites?
Log in only at app.maridoship.io, typed by you or from a bookmark. Our only official domains are maridoship.io and app.maridoship.io. Anything else, on any extension, is not us. We never ask for a password by email, phone or message. Report lookalikes to [email protected].
Is it available in my country?
Availability depends on where you are. Access is restricted in some countries, and the list may change. Where trading is offered, it is only through an executing broker licensed for your country. If we cannot offer you the service, you will not be able to reach the site or join the list.
How do I complain?
Email [email protected] with your name, the email address you used and what happened. We acknowledge formally within 48 business hours. Complaints about trading, money or accounts may also need to go to the broker and any ombudsman or dispute scheme that covers it.
No question matches that. Try another word, or write to [email protected].
