Quick Start

Up and running in minutes

01

Download and install

Use the code we emailed you to download the .dmg file, open it, and drag London5 to your Applications folder. The engine and simulator are bundled — no separate installation needed.

02

Launch London5

Open London5 from Applications. The engine starts automatically in the background. The interface connects instantly — no configuration required to get started.

03

Choose your model and data sources

Configure a local AI model or a cloud provider in Settings, then choose the market data sources for your research. Built-in paper accounts let you explore without connecting a live broker account.

04

Ask a question. Run a simulation.

Research a company or market, check the sources, and test an idea with paper capital. Review the run’s assumptions and journal. London5’s AI does not trade for you; you decide and trade at your own broker.
