tesser-core

Foundational data types shared across the entire workspace.

Overview

• Defines Candle, Tick, Order, Fill, Position, Signal, and supporting enums like Side, OrderType, Interval, etc.
• Contains no exchange-specific code; zero or minimal dependencies so every crate can rely on it.
• Provides helper methods (Interval::as_duration, Position::mark_price, etc.) used in both backtests and live trading.

When to Touch This Crate

• Adding/adjusting core types that must be shared everywhere.
• Extending enums to support new order styles or intervals.
• Never include exchange-specific logic—put that in connectors.

Tests

Run the focused test suite every time you change types:

cargo test -p tesser-core
