abaquant.marketdata.errors¶

Import path: abaquant.marketdata.errors

Domain: Provider-neutral market-data facades, normalized records, caching, and analytics.

Purpose¶

Exception hierarchy for optional market-data workflows.

When to use it¶

Defines domain-specific exceptions that callers may catch explicitly. Use this package to retrieve or inject quotes, price history, option chains, and financial statements while preserving a stable analytical interface.

Public objects¶

class: MarketDataError — Base class for failures in the applied market-data layer.
class: MarketDataProviderError — Raised when a configured provider cannot supply usable data.
class: MarketDataValidationError — Raised when public market-data inputs violate a domain constraint.
class: UniverseValidationError — Raised when a ticker-universe request is invalid.
class: InsufficientHistoryError — Raised when available aligned history is too short for a calculation.
class: PortfolioValidationError — Raised when an applied portfolio request or allocation is invalid.
class: PortfolioOptimizationError — Raised when an applied portfolio optimizer cannot produce a valid solution.
class: OptionalDependencyError — Raised when an optional market-data provider dependency is unavailable.

Detailed reference¶

Exception hierarchy for optional market-data workflows.

Purpose¶

The module defines domain-specific errors that distinguish provider, validation, history, portfolio, and optional-dependency failures.

Conventions¶

Exceptions carry human-readable messages and are raised instead of leaking provider-specific implementation exceptions from the public layer.
