Worked example — Trading the delay

The Packaging and Packaging Waste Regulation (PPWR)

When the highly contested PPWR was scheduled for a crucial ITRE committee vote, the market braced for strict plastic bans. However, our system caught a sudden procedural delay: a "referral back to committee" motion was filed on a Friday night. Quants long on European paper and packaging stocks traded the delay on Monday morning, weeks before the mainstream financial press reported the stalled regulation.

The Developer Experience

Parliamentary websites use arcane, localized terminology for legislative stages. We map them all to a standardized, English-language taxonomy (e.g. 'draft', 'committee_vote', 'plenary_vote', 'adopted', 'rejected').
