5-Minute Crypto Trend Following on Polymarket

How It Works Polymarket lists binary markets on whether BTC, ETH, or other crypto assets will be above or below a price level at a specific short-term expiry (e.g., 5 minutes). This strategy monitors the underlying spot or perpetual futures price of the asset for directional momentum signals and trades the corresponding Polymarket binary in the direction of the trend, exploiting any lag between the underlying market move and Polymarket price updates.

Entry/Exit Conditions A momentum signal (e.g., price crossing a moving average, RSI threshold, or rate-of-change trigger) on the underlying asset triggers a Polymarket trade in the corresponding binary contract. Given the 5-minute resolution, positions are typically held to expiry rather than exited early. Signal generation must be fast enough to capture the mispricing window before the Polymarket order book reprices.

Verified Results A dedicated dashboard repository exists (rexlau-prog/pm-crypto-trend-dashboard) for monitoring the bot's performance, suggesting the system is actively deployed and generating data. However, no P&L figures or win rates are disclosed in the available metadata.

Implementation Notes The dashboard architecture suggests a separation between the trading bot and reporting layer, which is good engineering practice. Real-time price feeds from a crypto exchange (likely via WebSocket) feed the signal generator. The bot must manage multiple concurrent 5-minute markets as new contracts open every 5 minutes. Position sizing must account for the high frequency of trades and cumulative fee drag.

Risks At 5-minute resolution, transaction costs (Polymarket fees plus gas) are a significant fraction of potential profit and can easily eliminate edge. Momentum signals in crypto are well-known and heavily traded by sophisticated participants, making the Polymarket binary likely efficient for obvious signals. Slippage in thin Polymarket order books can erode the edge identified in the underlying market. The strategy requires continuous uptime with no tolerance for downtime during active market windows.
