Up and running in three steps.
Install & open
Run the installer and launch Nebula. The free tier is active immediately - there is nothing to sign up for.
Connect MetaTrader
Point Nebula at your MT4 / MT5 terminal (any broker). It pulls your broker's own price history to test on - a demo account is perfect to start.
Start your first run
Pick a pair, pick a style, press go. Nebula is a MetaTrader strategy builder: it breeds and tests while you do something else, and survivors arrive graded, with their evidence attached.

Trading carries a high level of risk and can result in the loss of your capital. Simulated results are not reliable indicators of future performance. Nebula is a tool, not financial advice. Run new systems on a demo account first.
