The Core Strategy: Asynchronous Volatility Harvesting

Trader aswfadq1555 trades Polymarket's 15-minute Bitcoin and Ethereum Up/Down markets using a hybrid of two-sided market making, volatility harvesting, and asynchronous complete-set accumulation.

Principle 1: Building Positions where Up + Down < $1.00

The algorithm constantly keeps small maker bids on both sides of the market and accumulates them during different phases of intra-candle movement:

• Buys Up at 42¢ during a sharp dip
• Later buys Down at 53¢ during the rebound
• Complete set cost = 95¢ → 5¢ gross edge at resolution ($Payout = $1.00)

Principle 2: Directional Residual on Top of Paired Inventory

Instead of holding a purely symmetric inventory, the algorithm maintains a deliberate directional residual:

Example Execution:
• Accumulates 100 Up + 150 Down shares
• 100 Up + 100 Down form locked complete sets
• The remaining 50 Down shares maintain directional momentum exposure

Around 86% of all purchased shares form part of the risk-free paired position, while the remaining 14% acts as the directional alpha layer of the strategy.

Why High Frequency Micro-Trading Wins

With an average trade ticket of just $10.51 executed 324 times per hour, the bot avoids moving orderbook depth and incurs virtually zero slippage. Because all orders are passive maker bids, it pays 0% exchange fees.
