*Net edge = $1.00 − combined ask − official crypto taker fees (0.07 × p × (1−p) per side). The bot only paper-buys when this is at least +0.5¢/share with real depth on both sides. Most of the time the combined ask sits at 1.01 — that 1¢ is the market makers' spread.

How it works

Every 30 seconds the bot reads Polymarket's public order books for the current BTC, ETH and SOL 5-minute and 15-minute Up/Down markets. One Up share + one Down share always pays exactly $1 at settlement, so if both can be bought for less than $1 after fees, that's a locked-in paper profit. It records every snapshot for later strategy backtests (including Heikin Ashi, tested honestly on real recorded data). Full research: this strategy loses money for roughly two-thirds of bots that run it live — which is exactly why this one is paper only.
