# Portfolio (/documentation/portfolio)

[Members-only documentation](https://members.vectorbt.pro/documentation/portfolio/)

Portfolio modeling connects trading rules with a realistic simulation state and reconstructs the
result into orders, trades, positions, drawdowns, returns, and other analysis objects. This section
explains that lifecycle and the main simulation interfaces.

*   [From orders](https://members.vectorbt.pro/documentation/portfolio/from-orders): Simulate portfolios from explicit order information
*   [From signals](https://members.vectorbt.pro/documentation/portfolio/from-signals): Simulate portfolios from entries, exits, and stop logic
