Vantage News is a Pine Script library that provides pre-market economic event filtering defaults intended for strategies that trade on YM futures. It determines a default for whether trading should be blocked, delayed, or allowed on any given day.

Core Concept

News events are pre-compiled into Pine Script data libraries organized by half-year (LO1_News2025H1, LO1_News2025H2, etc.), updated weekly on Sundays. There are no API calls — events are baked into arrays of dates, times, type IDs, and severities.

Severity System

Can be configured to define or override three default severity tiers:

- Sev 3 (CPI, NFP, FOMC) — defaults to blocks the entire day or delays, depending on policy
- Sev 2 (ISM PMI, claims) — defaults to delay trading until the event time + a configurable post-delay window
- Sev 1 (secondary indicators) — defaults to no delays

Blocking vs Delaying
- Block: No trading for the full session. WillTradeToday() returns false.
- Delay: Trading allowed after eventTime + delayMinutes. IsDelayed(currentTimeMs) returns true until the release time passes.

Provides a per-event-type policy mechanism so overrides can force any event to block, delay, or be ignored regardless of its base severity.

Next Trading Window Calculation

FindNextTradingWindow() scans forward up to 14 days, skipping weekends and blocked days based on the provided configuration. If the next tradeable day has a delay, it returns the delayed start time — so an info panel can show e.g. "Mon 7:35 AM" to indicate the next trading opening

Exception Mappings

Each half-year library can ship per-event-type overrides (different severity, custom delay minutes, tags). When the applyLibExceptionMappings configuration is enabled, these override the base severity — allowing the data to carry date-specific adjustments.

Special Handling

CME early close days are encoded as a special event type. CheckCmeEarlyClose() returns a halt timestamp so a strategy can truncate the session.

Caching

Evaluation is lazy and memoized by date string — EvaluateForDate() only recomputes when the date changes. The event cache is built once at initialization via a day index for fast date lookups.
