Predicted Lineup Volatility Index

Overview

Analyzes a manager's rotation habits, player fatigue, and squad depth to forecast the stability of a team's starting lineup. This is crucial for identifying value in markets sensitive to surprise player selections.

What It Does

This pillar calculates a volatility score from 0 to 100 by tracking historical lineup changes for a specific manager and team. It synthesizes data on player minutes across all competitions, injury reports, and the importance of the upcoming match. A high score signals a high probability of significant lineup rotation.

Why It Matters

Unexpected lineups can completely invalidate a trading thesis, especially for player props and match outcomes. By quantifying this uncertainty beforehand, you gain a significant edge and can better price the risk associated with key players starting or being rested.

How It Works

First, the model analyzes the last 15 starting lineups to establish a manager's baseline rotation frequency. It then incorporates player load by tracking minutes played over the past 21 days. Finally, it adjusts the score based on the competition's priority, like a domestic cup vs. a key league match, to generate a final volatility index.

Methodology

The index is a weighted average: 50% Manager Rotation History (using a Jaccard index to compare consecutive starting lineups), 30% Player Fatigue (minutes played in the last 21 days vs. seasonal average), and 20% Competition Factor (a predefined weight for league, cup, and international fixtures).

Edge & Advantage

The market typically reacts to confirmed team news; this pillar predicts the likelihood of that news, giving you an edge hours or days in advance.
