tesser-portfolio

Portfolio accounting primitives: tracks cash, positions, and realized/unrealized PnL.

Overview

• Portfolio applies fills, updates entries/exits, and produces equity snapshots.
• Supports serialization via PortfolioState so live trading can persist and reload.
• Includes PortfolioConfig for setting initial equity and future risk parameters.

Typical Usage

• Backtester and live runtime call apply_fill_positions and then feed the resulting ledger entries through apply_ledger_entries whenever orders settle.
• Strategies can inspect positions through Portfolio::positions() via the StrategyContext.
• Live trading snapshots the state with portfolio.snapshot() and restores with Portfolio::from_state.
