The algorithmic pricing war on Toyota Hilux OEM filters.
Five competing Dhaka distributors. One SKU. Twelve weeks of intraday tier-price observation. The dataset that became the foundation of the JOY arbitrage engine.
For 12 weeks in mid-2025 we instrumented intraday tier-price observation on a single SKU: JA-OF-7821 — the Toyota Hilux N80 OEM oil filter. Five competing Dhaka distributors. 18,000 price points. One conclusion.
The conclusion.
Tier price for this SKU varied by up to 34% within a single trading day. The intraday min-max spread averaged 19%. The median price drifted 8% week-over-week without any underlying landed-cost change. This is the textbook signature of an inefficient market.
The dataset.
We are open-sourcing the cleaned dataset (CSV · 18,000 rows · 12 weeks · 5 distributors) to Series A diligence partners under NDA.
Why this is the foundation of the JOY arbitrage engine.
JOE now runs a continuous intraday observation loop on the top 1,400 SKUs across all 5 hubs. Tier-locked pricing is the most under-engineered surface in the South Asian aftermarket — and we believe it is where the next $1B of margin lives.
