Live tracking and drift alerts
Mission Control sets each live system against the range its test modelled, and tells you when one drifts. Pause, resume or close it.
It proves a replacement first
Pick a slipping system and Nebula retests reserves from your library on recent price. If none holds up, nothing changes.
Ultimate can replace it for you
It swaps in a tested replacement when a system stops behaving like its test. It reacts to results, not a timer.
Your desk on your phone
Connect your own Telegram for alerts and questions about your systems. Replies come from your computer, so keep it on.

Straight answers before you pay
You make every call.
You choose the market, the rules and the limits. Nebula builds and tests what you ask for. It gives no advice.
No promised results.
Test results are simulated. Live trading can do worse than any test.
It cannot make a weak edge strong.
A run can end with nothing worth deploying.
Your computer has to stay on.
Your EAs run inside MetaTrader, so it must be running for them to trade. A VPS keeps it running when your computer is off.
Buying an EA or building one.
A bought EA comes with someone else's rules and someone else's test. Nebula shows you the rules and how yours was tested.
MT4 or MT5.
Both on paid plans. Free deploys to MT5. If a system cannot run faithfully on MT4, Nebula refuses the MT4 deploy.
If you cancel.
You keep access to the end of the period you paid for. Then you drop to the highest lifetime plan you own, or to Free. Your vault stays yours, and EAs already in MetaTrader keep running.
Runs on your own computer
- Windows 10 or 11, 64 bit
- macOS 11 or later on Apple Silicon, or 10.15 or later on Intel

Common questions
Do I need to code?
No. You choose the market, the rules and the risk. Nebula writes the EA.
What does Free include?
The same search and tests as paid plans, one symbol per run. Free includes one real deploy to MT5, one system, once.
How does the forward check work?
Each system you keep is retested on price that arrived after it was built, and Nebula scores how often its grades called the outcome. It is simulated on your own data, not live trading.
Does it work on Mac, and with MT4?
Yes. Nebula runs on Windows and Mac. Paid plans deploy to MT4 and MT5. Free deploys to MT5.
What is the cooling off?
14 days, and it ends when you download the installer or activate a key. After that there are no refunds. See the refund policy.
Is my data shared?
Anonymised strategy research data goes to a shared research pool by default, and you can switch it off. Performance results are shared only with your consent.
How do I activate a key?
Open Nebula, go to Settings, then Licence, and paste your key.
