Polymarket Arbitrage Bot 如何運作 — 從掃描到執行

逐步說明 Polymarket Arbitrage Bot 如何識別低於 $1 的 binary YES/NO 總和、組合多結果定價失衡與末端收益，然後分配腿位並同時觸發 gasless FAK 訂單。

Step 1
Scan
PolyArb subscribes to the Polymarket Market Channel WebSocket and pulls best-bid / best-ask updates for every active market. Whenever the sum of best-ask prices on a binary or multi-outcome market drops below $1.00, a candidate fires.
Step 2
Size
A candidate is sized against book depth, the live taker fee for that category, and your configured maximum capital per trade. If the post-fee EV is positive, the candidate becomes an order plan.
Step 3
Fire
PolyArb fires every leg as a Fill-And-Kill order through the Polymarket Relayer in the same batch. If any leg fails, the others are cancelled — leg risk is bounded by the slippage protection built into FAK orders.
Step 4
Settle
Tokens stay in your wallet until resolution. After UMA reports the outcome, you redeem winning tokens for $1.00 each through the standard CTF redeem flow.
