📖 How It Works
1. Your bias indicator flips (BULL↔BEAR) → signal arrives here
2. Engine starts a buffer timer — waits to confirm bias holds (not just noise)
3. If bias holds through buffer → checks runway (enough time left in 5-min window?)
4. Both pass → ENTER trade (buy Up or Down token on Polymarket)
5. Window expires → if correct, token pays $1.00. If wrong, lose bet.
Buffer + Runway = total time needed. Example: 60s buffer + 120s runway = flip must happen within first 2 min of a 5-min window.
