polymarket-copy-trader

This repo from the same author as polymarket-weather-edge takes a research-first approach to copy-trading. Rather than promising profits, it explicitly measures the real-world friction that makes copy-trading difficult: the delay between a smart-money wallet's trade and your bot detecting it, the resulting slippage from trading after the signal, and the PnL impact over time. The description says 'measure what a copier actually gets' — a refreshingly honest framing. The implementation appears to track a predefined set of 'high-conviction' wallets (likely identified by win rate, trade frequency, or total volume) and paper-trades their moves, recording timestamps, fill prices relative to original trade, and running PnL. This is valuable research infrastructure: anyone considering copy-trading on Polymarket can use this to determine whether the strategy has any edge after accounting for detection delay and slippage. The 71KB size suggests focused, minimal implementation. For traders exploring copy-trading strategies, this provides the measurement framework needed to make informed decisions. The author's previous work (weather-edge) suggests technical competence. Clone this before any copy-trading bot to understand the realistic friction you'll face.
