## Order Book Depth Erosion

Order book depth refers to the total volume of buy and sell orders at various price levels. Erosion occurs when these orders are removed from the market, leaving a gap between the best bid and the best ask.

This happens when market participants become fearful or when algorithmic trading bots stop providing quotes. Shallow order books make an asset extremely susceptible to price manipulation.

Even small trades can cause massive fluctuations, which further scares away participants. This creates a negative feedback loop that can destroy an asset's market utility.

For institutional traders, low depth makes it impossible to enter or exit positions without moving the market. It is a key indicator of market health and systemic stability.

Maintaining deep order books is essential for the long-term viability of any financial instrument.
