Nebula - the no-code EA builder

What is Nebula?

Nebula is a no-code genetic strategy engine. It generates, evolves and stress-tests thousands of trading strategies on your own hardware, then compiles the survivors into ready-to-run MetaTrader 4 or MetaTrader 5 Expert Advisors. You set the goals and constraints; the engine does the building. See how Nebula works.

Is there a free version of Nebula?

Yes. Nebula Free is a full download with no payment required - you can evolve and inspect strategies and deploy a real system to your own MetaTrader terminal. Start free - no card and upgrade to Starter, Pro or Ultimate whenever you outgrow it.

Do I need to know how to code?

No. There is no programming involved at any stage - strategy generation, validation and the final Expert Advisor are all produced by the engine.

What do I need to run Nebula?

A Windows PC, a Mac, or a VPS with MetaTrader 4 or 5 installed. Nebula connects to your own terminal and runs on your own hardware - your data and strategies stay with you.

How does Nebula avoid overfitting?

Every candidate strategy is judged on out-of-sample data it never trained on, with walk-forward validation and anti-overfit checks built into the evolution itself. Pro and Ultimate add Monte Carlo robustness reports. Read the full explanation in overfitting and walk-forward testing, explained.

Does Nebula guarantee profits?

No, and you should be wary of any trading tool that claims to. Nebula gives you a rigorous process for building and validating strategies; live results depend on markets, your broker, and your own risk decisions. Past and simulated performance is not a reliable indicator of future results.

Can I use Nebula strategies on a prop-firm account?

Nebula Pro and Ultimate include configurable hard daily and total drawdown caps you can set to match a prop firm's rule set, so candidates that would breach those limits are filtered out during evolution. Passing a challenge is never guaranteed - always check your firm's current rules on EAs before trading.

The Systems Library

What is the Nebula Systems Library?

A catalogue of complete, rules-based trading systems built and validated with Nebula. Each purchase includes a 15-page playbook - the edge, exact entry, exit and stop rules, sizing, a worked trade on real price data and the full performance breakdown - plus a free deploy of the same system as an Expert Advisor through the Nebula app. Browse the library.

Are Systems Library purchases subscriptions?

No. Each system is a one-time purchase. It is not a signal service - you get the complete rules and the EA, with nothing further to follow.

How are library systems tested?

Every system is published only after holding up in Nebula's out-of-sample validation - evidence that was not used to build it. Figures shown are simulated results, not live track records.

TradingView indicators

How do I get access to the TradingView indicators?

Our indicators are invite-only scripts on TradingView. Enter your TradingView username at checkout and access is granted to your account - a one-time purchase gives lifetime access to that script.

Licensing, billing and refunds

How does Nebula billing work?

Monthly, 3-month, 6-month and 1-year plans renew at the same price until you cancel. Lifetime is one payment that never expires and includes all future updates. Licences are single-activation and machine-locked to one device. See the pricing page for current plans.

When does my licence term start?

When you first activate the key inside the app - not at the moment of purchase - so buying early costs you no licence time.

Can I get a refund?

See our refund policy for full details before you buy.

Is Orion RFX a broker or fund?

No. Orion RFX builds trading software and educational material. We never hold client funds, execute trades for you, or provide financial advice. Everything on this site is educational; trading involves risk and past performance is not indicative of future results.
