Insider Advantage Detector

Overview

This pillar analyzes trading patterns to detect the potential presence of insider information. It helps traders identify and avoid markets where a few participants may have an unfair, unpriced advantage.

What It Does

The Insider Advantage Detector monitors for statistical anomalies in market activity. It specifically tracks sudden, unexplained spikes in trading volume and significant widening of the bid-ask spread. These signals are compared against historical baselines to flag activity that deviates from normal public speculation.

Why It Matters

Information asymmetry is a major risk in prediction markets. This pillar provides a crucial defensive edge, helping you avoid markets that are likely being manipulated or are heavily influenced by non-public knowledge, thus preserving your capital.

How It Works

First, the pillar establishes a baseline of normal trading volume and spread width for a given market category. It then monitors real-time trading data, looking for deviations that exceed statistical thresholds, such as a volume spike three times the recent average. When multiple anomalies are detected simultaneously without a clear public cause, the pillar flags a high probability of insider activity.

Methodology

The analysis calculates a Z-score for trading volume against a 30-day moving average to identify significant spikes. Spread width is measured as (Ask Price - Bid Price) / Mid-Price and monitored for sudden increases greater than two standard deviations from the norm. These events are weighted more heavily if they occur in a low-news environment or in the 24-48 hours preceding a scheduled announcement.

Edge & Advantage

This pillar's edge is risk mitigation. It systematically identifies high-risk markets where the average trader is at a disadvantage, allowing you to focus on fairer opportunities.
