15-Minute BTC Up/Down Arbitrage

This TypeScript bot (Juanp2389/Kalshi-trade-bot) identifies discrepancies between Polymarket and Kalshi BTC 15-minute binary options. It places opposing trades on both platforms when the implied probabilities diverge by more than a configurable threshold, capturing the spread as a risk-free profit. Entry triggers when the bot detects a gap; exit occurs at market resolution or if the gap closes early. The repo targets both platforms simultaneously, using each platform's API. Implementation requires separate accounts and API keys for both Polymarket and Kalshi. Risk is minimal if spreads are captured correctly, but execution latency and platform resolution differences must be managed.
