The red dashed line is the Price to Beat — it stays flat for the entire 5 minutes. Exchange prices move around it. If they're above at the end, "Up" wins.

Positive = exchanges say BTC is higher than what Polymarket set. Negative = lower. A consistent gap means there's a systematic difference between Polymarket's reference and the live market.

Green = "Up" share price, Red = "Down" share price. Each ranges from $0.00 to $1.00 and they roughly mirror each other. Watch the final 30 seconds — sudden crossovers or spikes may indicate manipulation or last-second large trades.
