Trading, done for you.
Nebula builds, tests and runs trading systems on your machine - so you can be in the markets without the screen time, the coding, or the guesswork.
How it works
It breeds strategies. Only survivors reach your account.
You pick a market and a style. Nebula evolves thousands of candidates, kills the ones that only look good in hindsight, and hands you the survivors with an evidence file.

You choose a market and a style. Nebula does the part that takes humans years: it evolves thousands of candidate systems, kills the ones that only look good in hindsight, and hands you the survivors with an evidence file.
Breed
A genetic engine evolves strategies from proven building blocks on your pair and timeframe.
Learn moreShow less
A genetic engine assembles strategies from proven building blocks and evolves them against real market data on your pair and timeframe. No code, no formulas - you set the goal, it does the search.
Prove
Every candidate is retested on data it has never seen. Survivors carry a confidence grade.
Learn moreShow less
Every candidate is retested on data it has never seen - out-of-sample and blind windows - and run through anti-overfit gates. Each survivor carries a confidence grade and the full test record behind it.
Deploy & watch
One click installs it in MetaTrader with your risk limits baked in. Mission Control watches it live.
Learn moreShow less
One click installs the strategy in MetaTrader as a compiled EA with your risk limits baked in. Mission Control then tracks it live and warns you when a system drifts from its tested behaviour.
What's inside
The features people don't expect from an EA builder.
Real screenshots from the shipped app. Every figure on them was earned in testing, not typed in.
Pick which strategy families the engine may breed from - your thesis, evolved.
Learn moreShow less
On Ultimate, DNA Selection lets you choose exactly which building-block families the gene pool draws from: momentum, breakout, Wyckoff, smart-money, order-flow and more. The search still runs at full depth; it just runs inside your idea.
Out-of-sample and blind windows, then a replay in MetaTrader's own tester.
Learn moreShow less
Every candidate is retested on data it never trained on and pushed through anti-overfit gates built to kill lucky curves. Because the strategy compiles to native MQL, Nebula cross-checks its own simulation against MetaTrader's Strategy Tester - the EA you deploy is the one that was tested.
Every system keeps its grade, lineage and full test record. Nothing is ranked on a backtest alone.
Learn moreShow less
Survivors land in your Vault with a confidence grade, their trade sample, drawdown profile and out-of-sample behaviour attached. Grades never quietly disappear, and the passed-genome archive is unlimited - your history stays yours.
Combine survivors into one balanced book instead of ten bets on one idea.
Learn moreShow less
The portfolio engine mixes your systems into a single book, sizing every leg on its own account basis and rewarding genuine diversity between them. Caps are set where the maths stops being honest, not where a marketing tier says so.
A compiled MT4 / MT5 EA on your chart, risk limits baked in, every deploy recorded.
Learn moreShow less
Deploy compiles the chosen system to a native Expert Advisor and installs it into your terminal - no copying files, no code. Position caps, drawdown limits and your high-impact-news rule are compiled into the EA itself on every deploy, and every deploy is stamped with which run bred it and what it scored.
Watches every live system against its tested profile and flags drift early.
Learn moreShow less
Markets drift and every strategy eventually decays. Mission Control tracks each deployed system against the behaviour it proved in testing. Pause, resume or flatten any live system from the app, set one drawdown ceiling for the whole account, and from Starter review a like-for-like replacement from your vault with a fresh micro-retest as proof; on Ultimate a decayed system can be retired and replaced automatically.
Drag a risk slider and see return and drawdown restated for any account size.
Learn moreShow less
In the Inspector, the size lens restates a system's recorded results at whatever account size and risk you choose - straight off the recorded curve, not a projection. It makes the real binding limit visible before you deploy.
Tell the engine what counts as a pass. It only shows you systems that meet your bar.
Learn moreShow less
Set your own acceptance rules - minimum win rate, streak asymmetry, lifecycle - and the search respects them. You dictate what passes; the engine does the work of finding it.
Firm-style rule templates and a breach simulator, before anything goes live.
Learn moreShow less
Load a rule set - daily loss limit, max drawdown, position caps - and the limits are enforced in the compiled EA. Nebula replays your candidate against the rules and shows where it would have breached, so you find out in a simulation, not on your challenge. No software can promise a pass, and we don't.
The app runs in 19 languages, switchable in one click.

Nebula's interface is translated into 19 languages, chosen from a picker in Settings. Your systems, grades and Telegram replies all follow the language you pick.

Latest update · 9 September 2026
New in Nebula 0.4.47
0.4.47 adds Autonomous mode (beta, Ultimate): set a goal and a time budget and Nebula searches, tests and grades on its own. Also new: The Nebula, one page showing which of your systems cover each other's bad days; alerts that stop repeating once dismissed; a risk stop that confirms it really froze entries; faster forward-data updates; and high-frequency runs returning results again. Nebula updates itself on launch.
Also new since 0.4.45 · all live now
A risk-per-trade slider on Deploy, with the best-chance mark taken from your system's real replay.
Learn moreShow less
Every deploy now starts from the risk the system was actually tested at. Slide it and Nebula restates the outcome from the recorded curve, and marks where the odds were best. A 5% per-trade wall stays in place whatever you pick.
Pick a target and a horizon; reach and breach odds recompute per setting, on one bar each.
Learn moreShow less
The risk-to-goal ladder on the Portfolio tab reads your book's real ledger and shows, for each risk setting, the chance of reaching the target against the chance of breaching your drawdown limit first. Change either input and the ladder rebuilds.
A proof that ran on part of a book now reads "N of M legs" instead of a bare survivor count.
Learn moreShow less
If a portfolio's forward proof could only replay some of its legs, the badge now says so up front, so a partial book is never mistaken for a full one.

Nebula was built for someone who works 9 to 5: the searching, testing and monitoring run unattended on your machine, and the whole operation fits in the gaps of a normal day.
Start an evolution run before work or before bed. The engine breeds and tests on its own; results are waiting when you're back. Nothing needs babysitting.
Text your desk on Telegram from the office: "how are we doing", "any open positions", "risk check". Nebula answers with the real numbers from your own machine.
Mission Control tracks every deployed system against its tested profile and flags drift. On Ultimate, a decayed system can be retired and replaced automatically.
You never see a line of MQL. Configure a run in plain controls, read results as grades and charts, and export a finished EA. The hard part is the engine's job.
Everything runs locally on your Windows or macOS machine with your MetaTrader terminal. Your data, your broker, your hardware - nothing lives on someone else's server.
Position size caps, drawdown limits and news-avoidance windows are set before deploy and compiled into the EA itself - the EA enforces them even when you're not looking.

Telegram remote desk
Your entire operation, one text away.
Link your Telegram and ask your desk in plain English - portfolio, open positions, risk, run progress - and every reply comes from what your own machine actually knows.

Link your Telegram and the desk answers you like a colleague. It understands plain English - over twenty kinds of question about your live portfolio, open positions, risk, run progress and system health - and every reply is built from what your machine actually knows. No cloud middleman, no canned answers.
It also speaks first: deploy confirmations and monitoring alerts reach your phone as they happen, so a quiet phone means a quiet book.

Polaris - the hive mind
Every member's experience makes your engine smarter.
Every installation contributes anonymised backtest outcomes to one shared pool, so your engine trains on the whole network's experience, not just your own runs.
Learn moreShow less
Most trading software learns from one person's history: yours. Nebula ships with Polaris, a shared machine-learning pool where every installation contributes anonymised backtest outcomes - which strategy structures held up out-of-sample and which quietly decayed. Sharing is part of the install agreement and on by default; it never includes live results or account data, and you can switch it off in the app at any time.
Your engine trains on the whole network's experience, not just your own runs. And it compounds: every new member widens what every other member's engine has seen.
Sharing is covered by the install agreement; you can see exactly what you contribute - and switch it off - inside the app.
Funded & prop-firm accounts
Built to trade inside the rules.
Challenges are lost to rule breaches as often as to bad trades. Prop-firm mode is designed around the rulebook itself, so the machine holds the discipline a tired human can't.

Prop-firm challenges are lost to rule breaches as often as to bad trades. Nebula's prop-firm mode is designed around the rulebook itself - so the machine holds the discipline a tired human can't.
Load a firm-style rule set - daily loss limit, max drawdown, position caps - and the limits are enforced in the compiled EA, not in a note on your monitor.

Nebula reviews · verbatim from Trustpilot
“Nebula is unlike anything I’ve ever used or seen. It’s not just a producer of EAs. It builds every one with your input and parameters.”
“I have certain requirements for my trading strategy and pre-programmed trading robots did not fit me. Nebula allows you to create a custom EA based on your requirements for MetaTrader 4 and 5.”
Monthly plans renew at the same price until you cancel. Lifetime is one payment. 14-day cooling-off before you download or activate.
Trading foreign exchange and CFDs carries a high level of risk and can result in losses exceeding your deposit with some brokers. Simulated and past performance are not reliable indicators of future results. Nebula is software - a tool, not financial advice - and no result is guaranteed.
Deploy · free tier includes one real deploy
One click. An EA on your chart.
One click turns the system into a real MT4 or MT5 EA and installs it in your terminal. Your position caps, drawdown limits and news rule are built in.
Mission Control · Starter and above
It watches the book after you deploy.
Every live system is checked against how it behaved in testing. Pause, resume or close it from the app. Set one drawdown limit for the whole account. Drift is flagged early.
Autonomous mode · Ultimate · beta
Set a goal. Walk away.
Pick a goal and a time limit. Nebula searches, tests and grades on its own until the goal is met or time runs out. Then it reports what it met, its best, and where it gave up.
