Your trading idea,
fully automated.

Q: Do I need to know how to code?

No. Explain your entries, exits, indicators and risk rules in plain English, or draw them on the chart, and Opus Algo writes the Python. The code is always visible and editable, but you never have to touch it.

Q: Does it work on a Mac?

Yes. Building, backtesting and optimising happen in your browser on any computer, and the TradingView export runs in any browser. For MetaTrader 5, use its Mac app or a Windows VPS.

Q: How realistic are the backtests?

Tests run on tick-level data reaching back to 2003 on major FX and metals pairs, with real spreads plus modelled slippage and commission on every fill.

Q: Which markets can I trade?

More than 1,600 markets across shares, forex, metals, crypto, indices, commodities and bonds.

Q: What happens if I run out of AI credits?

Backtests and optimisation jobs keep running, and the strategies you exported are yours. On Pro or Max you can top up AI credits from $10 or wait for your monthly allowance to refresh.

Q: Can Opus Algo guarantee profits?

No. Opus Algo is a tool for building, testing and running your own ideas. You decide what to trade and how much to risk, and markets can always behave differently from the past.

Describe a strategy in plain English or sketch it on the chart. Opus Algo writes the code, backtests it on tick data back to 2003 and exports it to MetaTrader 5 or TradingView. No coding required.

Most trading ideas never make it past the notebook.

Turning a strategy into a bot has always meant picking a detour. Each one costs you time, money or confidence.

Learn to code

Months of Python or MQL5 before a bot behaves the way you meant. Most traders stop long before that.

Cost~~6 to 12 months~~

Hire a developer

Specs, back-and-forth and a new invoice for every tweak. Your edge ends up in someone else's head.

Cost~~Weeks per change~~

Ask a chatbot

You get code. Whether it trades the way you think, on real data with real costs, is anyone's guess.

Risk~~Untested logic~~

Opus Algo removes the detour. Idea in, tested strategy out, in minutes instead of months.

How it works

From a sketch on the chart to a strategy in the market.

Five steps, no code, and you approve every one of them.

01Draw

Mark the trade. Skip the code.

Click where you'd buy and where you'd get out, then say why in a sentence. Opus Algo reads your markup like a trading partner would: price, context and intent.
- Entries, exits and stops right on the chart
- Plain-English notes become precise rules
02Define

Answer a few sharp questions.

Trailing stop? Break-even? Risk per trade? Session filter? The AI asks what a chart can't show, then writes clean, commented Python you can read line by line.
- Clarifying questions, not guesswork
- Readable code, fully editable
03Backtest

Prove it on real ticks.

Replay the strategy across years of tick history with real spreads, slippage and commission. Inspect the equity curve, the drawdowns and every single trade.
- Tick data reaching back to 2003
- Trading costs modelled on every fill
04Optimise

Find settings that hold up.

The cloud optimiser runs thousands of parameter combinations in parallel and shows where your edge is robust, and where it's only curve-fitting.
- Thousands of backtests per job
- Fragility check built in
05Export

Run it on MetaTrader 5 or TradingView.

Download your strategy as an MT5 Expert Advisor, a TradingView Pine Script strategy or clean Python, and run it at whichever broker you already use.
- One-click export
- Your code, yours to keep

Questions, answered.

Can't find what you need? Talk to the team. Real people, quick replies.

Do I need to know how to code?

Not at all. Explain your entries, exits, indicators and risk rules in plain English, or draw them on the chart, and Opus Algo writes the Python. The code is always visible and editable if you're curious, but you never have to touch it.

Which brokers and platforms does it work with?

Any broker that offers MetaTrader 5, plus TradingView. Export your strategy as an MT5 Expert Advisor or a Pine Script strategy and run it where you already trade. There's no broker API, exchange key or plug-in to set up. If you can log in to MT5, you're ready.

Where do my strategies actually run?

Wherever you choose. Export the strategy and run it in your own MetaTrader 5 terminal, on your PC or a VPS, or on TradingView. Your broker login never passes through our servers.

Does it work on a Mac?

Yes. Building, backtesting and optimising all happen in your browser, so any computer works, and the TradingView export runs in any browser. For MetaTrader 5, use its Mac app or a Windows VPS, which also keeps strategies online around the clock.

How realistic are the backtests?

As realistic as we can make them. Tests run on tick-level data, reaching back to 2003 on major FX and metals pairs, with real spreads plus modelled slippage and commission on every fill. No backtest can promise future results, but ours are designed not to flatter you.

Which markets can I trade?

More than 1,600 across shares, forex, metals, crypto, indices, commodities and bonds. Strategy logic is portable, so an idea you prove on NAS100 can be tested on Bitcoin or gold in a couple of clicks.

Is there a free plan?

Yes. The Free plan includes three AI messages to turn your idea into a working strategy with a backtest preview, plus drawing on the chart, with no credit card. Upgrade to Pro or Max when you're ready to keep building, backtest, optimise and export the full code.

What happens if I run out of AI credits?

Your backtests and optimisation jobs keep running as normal, and the strategies you exported are yours. On Pro or Max you can top up AI credits from $10 at any time, or wait for your monthly allowance to refresh.

Can Opus Algo guarantee profits?

No, and be wary of anyone who says they can. Opus Algo is a tool for building, testing and running your own ideas. You decide what to trade and how much to risk, and markets can always behave differently from the past.

Your next strategy is one sentence away.
