Pressure Index

The Pressure Index is a dynamic, real-time metric that quantifies momentum, territorial control, and the intensity of a team’s physical presence. It serves as a barometer for both offensive dominance and defensive disruption.

Game Flow Index

A composite model for estimating match intensity and tactical dominance, derived from SSTrader's per-team Pressure Index.

Input signals

SSTrader Pressure Index (per team)

Range	Label	Description
`0 – 10`	No pressure	Team is primarily defending, sitting deep
`10 – 30`	Balanced	Evenly contested, neither side dominates
`30 – 50`	Pressing	Team is actively pressing and attacking
`50 – 60`	High pressure	Sustained aggressive pressure on opponent
`60 – 80`	Max attack	Maximum attacking intensity, all-in

Derived calculations

Two-axis framework

Total Sum = Home Index + Away Index — Determines overall match tempo
Delta = |Home Index − Away Index| — Determines tactical dominance

Axis 1 — Tempo

Sum (Home + Away)	Tempo tag	Expected match character
`0 – 20`	Dead Game	Both teams passive, low energy, slow transitions
`20 – 40`	Balanced Tempo	Moderate pace, structured, few open chances
`40 – 70`	Open Game	Good flow, both sides creating, end-product likely
`70 – 100`	High Intensity	Fast, aggressive, chances at both ends
`100 – 140`	All-Out War	Max pressure from both sides, chaotic, high volume

Axis 2 — Control

Delta `\|H − A\|`	Control tag	Interpretation
`0 – 10`	Neutral	No dominant side, genuinely contested
`10 – 25`	Slight edge	One team has a marginal territorial advantage
`25 – 45`	Clear control	Structural superiority for one team
`45+`	Total dominance	One team completely imposing their game

Combined archetypes

Archetype	Condition	Description	Betting signal
Trench War	`Sum < 20`	Both teams defending. Minimal transitions, very few shots.	Goals under, corners under, 0–0 HT
One-Sided Push	`Sum 20–50`, `Delta > 25`	One team attacking relentlessly, the other sitting back and absorbing.	AH favor attacker, corners over, 1X2 lean
Tactical Battle	`Sum 20–50`, `Delta < 15`	Balanced, mid-block chess match. Few clear-cut chances but quality over quantity.	BTTS, 1–1 or 1–0, moderate corners
Open Game	`Sum 50–80`	Both teams pressing and creating. Open spaces, good tempo, multiple chances expected.	Goals over, BTTS yes, corners over
End-to-End	`Sum 80+`	Maximum bilateral pressure. Chaos, high volume, both teams vulnerable defensively.	Goals over, corners over, cards likely

Examples

Teams	Sum · Delta	Archetype
Home 8 · Away 6	Sum 14 · Delta 2	Trench War
Home 45 · Away 5	Sum 50 · Delta 40	One-Sided Push
Home 28 · Away 25	Sum 53 · Delta 3	Open Game
Home 38 · Away 18	Sum 56 · Delta 20	Open Game + Slight edge
Home 62 · Away 55	Sum 117 · Delta 7	End-to-End
Home 22 · Away 20	Sum 42 · Delta 2	Tactical Battle

Practical Application & Use Cases

Live Momentum Tracking: This metric powers real-time "ebb and flow" visualizations, allowing analysts and viewers to identify which team is currently dictating the tempo, even if the scoreline remains level.
Tactical & Physical Monitoring: It helps identify "structural fatigue." A sharp decline in a team’s Pressure Index during the final 20 minutes often signals a physical drop-off, providing critical data for substitutions or live betting adjustments.
