AVC — Abnormal Volume Calculator
Event studies on trading volumes. Detect liquidity, attention, and insider-trading patterns around events.
What it does
The Abnormal Volume Calculator (AVC) computes event studies on trading volumes rather than returns. Abnormal volume often precedes return reactions and signals new information entering the market.
Supports the same event-window framework as ARC, applied to volume time-series.
How it integrates
The AVC computation runs on a separate R-backend (open source, peer-reviewed). The Drupal frontend you're reading provides documentation, examples, and access; the calculation API is bridged via Cloudflare Workers and accepts CSV uploads or single-event JSON payloads.
