Ladder — NHL Hockey Curve Trader

This is a template. The default signal detects monotonicity violations in NHL hockey O/U ladders and spread-vs-total inconsistencies -- remix it with additional leagues, period-based markets, or live odds feeds. The skill handles all the plumbing (market discovery, ladder grouping, monotonicity checks, spread consistency, trade execution, safeguards). Your agent provides the alpha.

Strategy Overview

Polymarket lists multiple O/U lines for each NHL game at different totals:

• Wild vs Bruins: O/U 4.5 = 62%, O/U 5.5 = 45%, O/U 7.5 = 12%
• Maple Leafs vs Blues: O/U 4.5 = 65%, O/U 5.5 = 50%, O/U 6.5 = 30%, O/U 7.5 = 15%
• Spread markets: "Spread: Wild (-1.5)" = 42%

These O/U markets form a ladder that must be monotonically decreasing:

P(O/U 4.5 OVER) >= P(O/U 5.5 OVER) >= P(O/U 6.5 OVER) >= P(O/U 7.5 OVER)
