Deployment, full source code handover and a support plan for updates, fixes and backups.

Starting prices for each kind of work are listed in the pricing section. After the first call you receive a written quote with a fixed price for the agreed scope, so the number doesn't move unless the scope does.
A company website can be ready in a few weeks. Web platforms and mobile apps usually take a few months. Your quote includes a timeline with weekly milestones.
You do. The full source code, along with hosting, domain and app store accounts, is handed over in your name.
Yes. We review what's there, explain the problems in plain language and fix them. For MetaTrader Expert Advisors we need the .mq5 source file, because compiled .ex5 files can't be edited.
No, and you should be wary of anyone who says theirs do. We build Expert Advisors that follow your rules precisely and include risk controls. Trading carries a high risk of loss. Read our full risk disclosure.
You can choose a support plan covering updates, fixes, backups and monitoring, or take a clean handover and manage it yourself.
Share a few details and we'll reply with questions, a suggested approach and next steps. No obligation.

We only collect what we need to reply to you and deliver your project. We don't sell your information, and this website doesn't use advertising or tracking cookies.
3HDS Services ("3HDS", "we", "us") designs and builds websites, web platforms, mobile apps and trading software for clients in the United Kingdom, Australia and Pakistan. You can contact us about this policy at hello@3hds.com.
We use your information to reply to enquiries, prepare quotes, deliver and support projects, send invoices, keep the records the law requires, and protect the website from spam and abuse. We don't sell your information or use it for unrelated marketing.
Under UK GDPR we rely on taking steps at your request before entering into a contract, performing our contract with you, our legitimate interest in running our business, and complying with legal obligations such as keeping tax records. Where we ask for your consent, you can withdraw it at any time.
We share information only when needed, with:
Our team works from Australia, the United Kingdom and Pakistan, and some service providers store data in other countries, including the United States. When information moves between countries, we take reasonable steps to keep it protected, including choosing providers that offer recognised safeguards.
We keep enquiries only for as long as we need them to reply and follow up. Client and invoice records are kept for as long as tax and accounting laws require.
This website doesn't use advertising or tracking cookies. When you choose a country in the pricing section, your browser remembers that choice in local storage on your device, and it isn't sent to us. The page loads its typeface from Google Fonts, so Google receives your IP address when the page loads. We may also use Cloudflare Web Analytics, which counts visits without cookies and without tracking you across other websites.
Depending on where you live, you can ask to access, correct or delete your information, object to or restrict how we use it, or receive a copy in a portable format. Email us and we'll respond within the time the law requires.
If you're unhappy with how we handle your information, please contact us first. You can also complain to the Information Commissioner's Office in the UK (ico.org.uk) or, where the Australian Privacy Act applies to us, the Office of the Australian Information Commissioner (oaic.gov.au).
We use reasonable measures to protect your information, including access controls and encrypted connections. No method of sending or storing data online is completely secure, so we can't guarantee absolute security.

These terms cover your use of this website and how we work with clients. Each project also has its own written quote or agreement, and where that document differs from these terms, the project document applies.
The content on this website is general information about our services. Starting prices are a guide, not an offer. Your price, scope and timeline are confirmed in a written quote before any work begins.
A quote sets out what we'll build, the price, the timeline and the payment schedule. Work starts once you accept the quote in writing. If you ask for changes outside the agreed scope, we'll explain how they affect the price and timeline before going ahead.
Payments are due as set out in your quote. If a payment is overdue, we may pause work until it's settled, and the timeline may move as a result.
Once your project is paid in full, you own the custom code and designs we create for it. Third-party components, such as open-source libraries, fonts, plugins and platform services, remain under their own licences. We may reuse our general know-how and tools that aren't specific to your project.
Our work often relies on services we don't control, such as hosting providers, app stores, payment providers, brokers and the MetaTrader platform. We aren't responsible for their outages, policy changes or price changes.
Expert Advisors and other trading tools follow the rules and settings you choose. We don't provide investment advice and we don't guarantee trading results. Please read our risk disclosure before using any trading software.
We carry out our work with reasonable care and skill. Apart from what your project agreement says, and to the extent the law allows, the website and our software are provided without other warranties.
To the extent the law allows, we aren't liable for indirect or consequential losses, lost profits, lost data or trading losses, and our total liability for a project is limited to the amount you paid us for that project.
Nothing in these terms limits rights you have under consumer protection laws that can't be excluded, including the UK Consumer Rights Act 2015 and the Australian Consumer Law.
Please don't misuse the website, including trying to break into it, disrupting it or sending spam through the contact form.
Your project agreement states which country's laws apply to that project and where any dispute will be resolved.
We may update these terms from time to time. Changes don't affect projects already agreed in writing.

Trading gold, currencies and other leveraged products carries a high risk of loss and isn't suitable for everyone. You can lose some or all of your money, and with some brokers and account types you can lose more than you deposit. Only trade with money you can afford to lose.
3HDS is a software developer. We code, test and set up trading software, such as MetaTrader 5 Expert Advisors and indicators, based on rules and settings you provide.
We are not a broker or a financial adviser, and we are not authorised by the Financial Conduct Authority in the UK, the Australian Securities and Investments Commission or the Securities and Exchange Commission of Pakistan to give financial advice. We don't recommend strategies, manage trading accounts for clients or hold client money.
No trading software can guarantee profits or protect you from losses. Coding a strategy accurately doesn't make it profitable, and we don't assess whether your strategy will make money.
Backtests, optimisation results and past performance don't reliably predict future results. Tests use historical data and assumptions that can differ from live trading, and strategies tuned too closely to past data often perform worse in real markets.
If anything here is unclear, email hello@3hds.com before you buy or use any trading software from us.
