PolyTraderBot

PolyTraderBot sells six self-hosted Polymarket trading bots: CopyBot (copy chosen wallets with your own sizing, filters and exits), Crypto5min and Crypto15min (5- and 15-minute crypto up/down markets), ARB (complement and negative-risk basket price gaps after costs), WeatherBot (temperature markets: forecast models against the price ladder) and PolyLiq (two-sided quotes in liquidity-reward markets). Each bot runs in Docker on your own PC or VPS, ships as full readable source (not compiled), starts in paper mode and keeps your private key on your own machine: no hosted signer and no custody. Updates install from the dashboard with a published changelog. $10/month per bot, source and updates included. No profit claims: trading prediction markets can lose money.
