Prevents Polytraders from trading against itself.

What it does

Prevents Polytraders from trading against itself. If an outgoing OrderIntent would cross with one of our own resting orders on the same market and outcome, SelfTradeWashGuard rejects it (full overlap) or downsizes it (partial overlap). This protects against wash-trade exposure and inadvertent self-fills.

Pipeline placement

runs after: exec.order_lifecycle_manager → SelfTradeWashGuard → runs before: exec.smart_router

Applies to: Per OrderIntent

Why it matters

If this fails	Consequence
Wash-trade liability	Crossing your own orders is treated as wash trading by most regulators and by Polymarket's own terms; even unintentional self-trades are a compliance risk.
Inventory churn	Self-fills move money from one account to another (or from one strategy book to another) while paying maker+taker fees both sides — pure deadweight loss.
Strategy interference	Two Polytraders strategies disagreeing on direction should not silently fund each other's positions through self-fills.
