Latin Square Rotation
Why Latin Square?
- Enables fair comparison across all model × behaviour pairs
- Eliminates market condition bias (bull/bear/sideways)
- Balances time-of-day and volatility exposure
- Enables statistical analysis of model vs. behaviour effects
Rotation Mechanics
- Each cycle lasts exactly 60 minutes (1 hour)
- Rotation occurs simultaneously for all agents at cycle end
- Complete experiment: 4 cycles × 60 minutes = 4 hours total
- Bankroll carries over; positions closed at rotation
Simulation Parameters
Slippage Model
Normal distribution centered at 11 basis points with standard deviation of 6 bps. Capped at minimum 2 bps and maximum 45 bps to reflect realistic market conditions.
Normal(μ=11, σ=6) ∈ [2, 45] bps
Latency Model
Log-normal distribution reflecting realistic network and exchange delays. Most trades execute between 200–800ms with occasional spikes due to congestion.
LogNormal(μ=5.4, σ=0.35) ∈ [120, 1200] ms
Position Sizing
Pareto distribution with behaviour-specific multipliers. Base distribution ensures occasional large positions while maintaining conservative average sizing.
Pareto(α=1.8) × behaviour_mult
Trade Frequency
Poisson process with micro-burst clustering. Normal intervals of 2–5 seconds with occasional 200–700ms bursts to simulate high-activity periods.
Poisson(λ=3.5) ◦ burst_clusters
