Executive Abstract

While institutional capital focuses on Premier League football and Thoroughbred racing, a structural anomaly exists in global betting markets: Greyhound Racing.

This audit postulates that Greyhounds represent the ideal "High-Frequency Trading" (HFT) environment. Unlike the low-velocity nature of horse racing, Greyhounds offer deterministic field sizes, embedded geometric biases (the "Coffin Trap"), and a 24-hour liquidity cycle that permits "Velocity of Capital" strategies unattainable elsewhere.

The Core Thesis

High Frequency + Deterministic Physics = Superior Risk-Adjusted Returns.

1. The Velocity of Capital

In systematic betting, Volume drives absolute ROI. Traditional horse racing models suffer from event scarcity. This simulator demonstrates the mathematical advantage of high-frequency greyhound turnover.

*Horse racing assumes fixed 5 opportunities/day. Greyhounds scale with input.

2. Structural Inefficiency: The Physics

Greyhound racing is a physics problem defined by rigid constraints. Unlike horse racing (variable fields), greyhounds run in fixed 6-dog fields, creating a closed-loop probability matrix.

3. Liquidity & 24/7 Operations

Low liquidity is the edge. By acting as Market Makers, we capture the spread before "Late Money" arrives. The strategy operates on a global axis.

4. Risk Management

Scaling stake size in thin markets requires specific protocols to avoid price destruction.

The "Drifter" Protocol

If the market moves against our position by >15%, the model assumes "Smart Money" knows something (injury/illness) not in the data.

ACTION: AUTO-LIQUIDATE (STOP LOSS)

Slippage Control

We never exceed 2% of the total matched pool on a single tick. For larger capacity, we utilize algorithmic BSP injection.
