Trade Polymarket BTC/ETH/SOL 5/15-minute fast markets with momentum and order book filters.
[!TIP] This is a template. The default signal is a Mean Reversion strategy using Binance momentum exhaustion and L2 order book imbalance. Remix it with alternative signals like trend-following momentum, social sentiment feeds, or cross-venue arbitrage models. The skill handles all the plumbing (market discovery, fee-accurate EV math, position tracking). Your agent provides the alpha.

"Momentum below threshold" — Asset move is too small. Lower min_momentum_pct if needed.
"Order book imbalance: neutral" — Market is balanced, signal skipped when require_orderbook=true.
"Time filter: low liquidity window" — Current hour is 02–06 UTC. Set time_filter=false to override.
