- a system saved to Genomes, or open on the Results leaderboard
What each plan gets
| Plan | MQL5 source (MetaTrader 5) | MQL4 source (MetaTrader 4) | cTrader cBot (C#) |
|---|---|---|---|
| Nebula Free | One export, once per install. A watermarked sample, not compiled or checked for deploy | No | No |
| Nebula Starter | Yes. Counts toward the one deployable system a day, the same as a deploy | Yes, same daily count | Yes |
| Nebula Pro | Unlimited | Unlimited | Yes |
| Nebula Ultimate | Unlimited | Unlimited | Yes |
Free's source export and Free's one deploy are separate. Using one leaves the other.
Steps: MQL5 source
Open the system
Open it from Genomes, or click a row on the Results leaderboard.
Open the Export menu
Press Export. Under Export code, hover MetaTrader: "The tested build. An MQL5 EA of this system".
Export code
- MetaTrader
- TradingView Pine
- cTrader
Press MetaTrader
Nebula writes the source at the risk the system was tested at. On Free, if your one export is already used, the plans box opens instead.
Read the banner
Paid plans: EA generated: with the file name and where it was written.
Free: Free sample EA exported: with the file name, "a watermarked sample, not compiled or checked for deploy", the path, and "This was your one free export."
The file name is the system's name, its symbol and timeframe, ending .mq5.
Install it yourself
Copy the .mq5 into your terminal's MQL5\Experts folder and compile it in MetaEditor. See How to install an EA in MT5.
Deploy does this for you on Starter and up, and puts it in Experts\Nebula.
Steps: MQL4 source
Connect Nebula to MetaTrader 4
The platform follows the terminal you are connected to. The Deploy tab's badge must read MT4.
Pick the system on Deploy
Click Deploy, then pick the system under Single systems.
Press Re-generate, then View source
Re-generate writes the source for the connected platform. View source opens it in the EA Source tab. Starter and up. Free is refused with "EA code generation requires Starter tier or higher." See How to install an EA in MT4.
Steps: cTrader cBot
Press cTrader in the Export menu
Hover reads "A cTrader cBot of this system, written in C#". Below Starter it carries a plan pill.
Read the notice
"cTrader fills and costs differ from MetaTrader. Results will not match the Nebula record. The MetaTrader EA remains the tested build." Under it: "Not compiled by cTrader here. Build it in cTrader Automate to check."
Save it
Press Save .cs and pick where to save it. Nebula confirms "cBot saved". Copy script copies it instead.

Questions
Is the free sample deployable?
It is real MQL5 source, stamped as a watermarked sample and not compiled or checked by Nebula. Use your free deploy if you want Nebula to compile and install a system for you.
Does a Pro export count against anything?
No. Pro and Ultimate export without a daily limit.
Is a bought Systems Library system limited?
A system you bought deploys on any plan without using your allowance.
