The Book Pressure Gauge tracks the real-time flow rate ratio of new bid orders versus new ask orders in the order book. When bid orders significantly outnumber ask orders, the gauge marker rises above its midpoint, indicating higher buying pressure. Conversely, greater ask orders push the marker below the midpoint, signaling higher selling pressure.

Key Points:

Extreme Conditions: If the bid-to-ask ratio becomes highly skewed, the gauge marker may exceed the red (selling pressure) or blue (buying pressure) lines, suggesting peak pressure conditions.

Trading Signals: Similar to other gauges, when the Book Pressure Gauge marker is above the red line, it may be a signal to consider selling, pending confirmation from other indicators. Conversely, below the blue line suggests a potential buying opportunity.
