GoodFallen

Overview

Self-hosted Python bot for Polymarket's 5- and 15-minute crypto Up or Down windows, sold as full source for $399 once and backed by the public Polymarket account its seller runs it on, @GoodFallen. It does not call direction: through each window it buys both Up and Down in small pieces, some at the ask and some as resting bids, never sells, and redeems the winning side after settlement. Taker fees eat most of the trading result, and Polymarket's daily rebates, which grow with volume, make up half of what the account keeps. Paper mode, a daily loss limit, an exposure cap, a stop file and Telegram reports are built in.

How it works

• The account checks out. On Oct 20, 2026 Polymarket's APIs showed @GoodFallen opened on Jul 16, 2026, $10.8 million traded across 23,276 markets, a profile profit of $192,667 before fees and 13th place on the month's Crypto leaderboard by profit. Its last 500 actions were 486 buys and 14 redemptions, with no sells.
• The site does the fee arithmetic itself, and the numbers hold. Polymarket's P&L feed puts the trading result at +$192,667 and taker fees at $126,223; the account's activity feed lists $60,015 in taker rebates over 93 daily payouts and $6,950 more for its resting orders. That leaves about $133,400 net, the figure the site prints, and half of it is rebates. Polymarket's all-time leaderboard, which counts fees but not rebates, credits the account with $66,252. Rebuilt from the same data, the daily log matches the site's: 80 of 95 days in profit, the worst −$1,658 on Sep 15.
• Two things the page does not stress. The account trades almost only Bitcoin's 5-minute windows: in samples spread over three months we found Ethereum once and no Solana or 15-minute fills, so the other markets the bot supports have no public record here. And both sides does not mean balanced: in a typical window the smaller side was about two-thirds of the larger, and the window the site charted when we read it held 155 Up shares against 378 Down, so each window still leans one way.
• The result leans on size. At $2.3 million of weighted taker volume over 30 days the account sits in Polymarket's top rebate tier and gets half its taker fees back; a new account starts with nothing back, and the lowest tier returns 3%. The site says so too: you will probably not make the same profit, and at small size the fees can outweigh the edge. Run paper mode at your own tier before funding a wallet.
