●●SolidDark Horse

Historical Polymarket data that doesn't exist freely anywhere else.

Strengths
  • •Fills a real gap — Polymarket doesn't provide historical order book access.
  • •Transparent about limitations: 2 months, not granular enough for competitive bots.
  • •26.8 million observations across 7 coins enables meaningful backtesting.
Weaknesses
  • •Only 2 months of data limits long-term strategy validation.
  • •It's a dataset, not a tool — value depends on what you build with it.

A Better Leaderboard for Polymarket

Shows more than raw P&L: six metrics, trader archetypes (DIRECTIONAL, ACCUMULATOR, ALGO_TRADER), persistent grades and filters (active/inactive, search by wallet) make it easy to scan for repeat winners. The UX puts useful columns up front — volume, predictions, win rate and a computed grade — but I want to see the methodology and survivorship controls up front; leaderboard data without clear adjustments can mislead casual users.

Polyoracle – Polymarket signal monitor with KL-divergence scoring

Uses KL divergence to give asymmetric moves the weight they deserve (a 5%→10% jump reads way louder than 50%→55%), then multiplies that by log-volume, historical SNR and trajectory consistency to surface genuinely interesting shifts. Practical engineering choices — persisted snapshots, rolling detection windows, cooldown dedupe and Telegram delivery — make this something you can drop into a trading workflow and actually rely on.
