ZCL Bot
Self-hosted TypeScript bot for Polymarket's 5-minute crypto Up or Down markets on Bitcoin, Ethereum and Solana, sold on Gumroad as full source for $99 once. It watches Binance's 5-minute candles and, after a run of same-direction candles, buys the opposite side of the next window. A losing bet is followed by a bigger one on a martingale ladder until a set number of losses stops the chain, with a price cap for each step, cancelling of unfilled orders near the close and automatic redemption of winnings. Backtest, paper and live modes are built in, and live orders need two separate switches turned on. The name, 斩长龙, is Chinese for “slaying the long dragon”: betting against a streak.

How ZCL Bot works
- There is no record to check. The seller, “kai xie” on Gumroad, has no other products, no reviews, no stated sales count, no website and no Polymarket account or wallet linked to the bot, so the strategy has to be judged on its own. In the category where live results are the easiest to show, that is a gap.
- The signal is thin. We pulled 90 days of Binance 5-minute candles, Aug 14 to Nov 12, 2026, and counted how often the next candle reversed a run. After three to five candles the same way it reversed 51–56% of the time across the three coins: a slight lean toward reversal, not a strong one, and it did not grow steadily with longer runs. Polymarket's crypto taker fee at 50¢ is 3.5% of the money spent, so a buy at 50¢ needs a 51.75% hit rate to break even before the spread. The edge, if there is one, is about the size of the fee. Polymarket also settles these markets on Chainlink's price, not Binance's candle, so the two do not always agree.
- The martingale does not change that arithmetic; it changes the shape of the losses. Doubling from a $1 stake, a chain stopped after six losses costs $63 plus fees to win back $1, and long runs come in clusters on 5-minute candles. The seller says this plainly: the page gives the maximum loss of a chain as base stake × (factor^n − 1)/(factor − 1) plus fees, calls these markets close to coin flips and promises no return. Use the backtest and paper modes with Polymarket's current fee before funding a wallet, and size the base stake from the chain's maximum loss, not from the hoped-for win.
- As software it is cheap and complete on paper: $99 for full source with three modes and a two-key live switch is less than the $399–$499 short-window bots in this catalog, which come with public accounts. We read the Gumroad page and the seller's storefront and ran our own candle count; we did not buy the bot, so the code, the backtest and the documentation are untested by us.
