Grok Bot builds a Polymarket quant volume trading system
A video shows a trader using Grok Bot agents to build an OBV-based ETH up-or-down strategy on Polymarket, reportedly netting about $13,937 in 13 days.
This guy used Grok Bot to build a Quant Volume system and it made $1,072 a day on Polymarket The result is already +$13,937 PnL in 13 days with about $144 per market traded, repeating the same setup roughly 42 times every hour across ETH "Up or Down" markets Several AI agents work together as one algorithm: 1. On-Balance Volume tracks whether trading activity supports the current ETH move The bot combines ETH movement with volume: Higher close → OBV = Previous OBV + Volume Lower close → OBV = Previous OBV - Volume Rising OBV means volume is accumulating behind upward movement Falling OBV means downward movement is receiving more confirmation This helps the bot distinguish sustained pressure from isolated moves 2. The OBV Signal Line confirms whether that pressure is continuing The system smooths the indicator: OBV Signal = EMA(OBV, 10) Then: OBV crosses above Signal → stronger Up confirmation OBV crosses below Signal → stronger Down confirmation A single volume spike is not enough. The bot waits for the accumulated flow to move in the same direction as the signal This is the first agent that will create a trading bot strategy for you and then build it:https://join.horizon.trade/Quant This trader’s Polymarket account: ply-pm2 Most profitable trades: $206 → $1,050 (+$844) $37 → $839 (+$802) $116 → $853 (+$737) The system uses OBV to detect volume pressure and its signal line to confirm whether that movement is continuing
