Olympus preview

Olympus

Copy Trading

Polymarket web terminal built around copy trading that keeps running on Olympus's servers after you close the tab. Every followed wallet gets its own ratio, trade and market caps, odds, liquidity and volume filters, a price-deviation guard and a limit mode that buys at the leader's own fill price, with stop-loss, take-profit, counter-trading and combo copying; a backtest replays the leader's history through those exact settings first, and separate trading wallets keep strategies apart. Around the copier: a manual terminal with a sports hub, crypto price windows, combos and TP/SL on any position; Bonds, which ranks every outcome priced 97¢ or more by what it pays after fees, and Autobond, which buys them inside a budget and a loss limit; an LP Rewards desk that places maker orders on Polymarket's reward markets; Polymarket Perps to 20x and Dimes Multiply positions to 10x; and a REST trading API with wallet-scoped keys. The base fee is 0.75% per executed trade, sliding toward zero at extreme prices. Built by the team behind SOL Decoder and Valhalla.

PolyTraderBot

Copy Trading

Six self-hosted Polymarket bots from one developer, sold separately at $10 a month each and delivered as full source with a browser dashboard, tests and a Docker setup for your own PC or VPS. CopyBot follows wallets you choose, or candidates it ranks from Polymarket's public leaderboard, with fixed, proportional or Kelly-fraction sizing, ten-plus individually switchable guards and exits that follow the leader out. Crypto5min and Crypto15min trade the 5- and 15-minute up/down windows on BTC, ETH, SOL, XRP, DOGE, BNB and HYPE from tree-based models retrained every 60 or 90 minutes. ARB scans the order books for binary YES and NO asks that sum to less than $1 after fees. WeatherBot prices temperature buckets from a weighted blend of Open-Meteo models, NWS, NOAA and Met.no forecasts and compares the result with the live asks. PolyLiq rests two-sided quotes in the markets that pay Polymarket's liquidity rewards, or takes over the resting orders you placed yourself. Every bot starts with real orders switched off, keeps the wallet key in a local env file and, from the current releases, updates itself from its own dashboard. The vendor advertises no returns; a free Polymarket terminal from the same developer is in beta on the same domain.
