In cryptocurrency trading, a “purchase wall” is a large purchase order, or a number of purchase orders, round a selected worth stage. Conversely, a “promote wall” is a major accumulation of promote orders at a given worth stage.
Earlier than understanding how purchase and promote partitions work, it is very important know what an order ebook and its market depth are.

Nonetheless, these orders don’t get executed randomly — quite, the market fulfills them within the order of their sequence.
For instance, two open orders are created when Peter Griffin makes an attempt to promote 1 Bitcoin (BTC) for $25,000 and Cleveland Brown locations an order to purchase 1 BTC at $24,000. Suppose Glenn Quagmire joins in and tries to promote 1 BTC for $26,000. Because of this, there are three unfulfilled, open orders.
However when a brand new purchaser, Joe Swanson, enters the market and tries to purchase 1 BTC for $26,000, he doesn’t get Quagmire’s coin. As an alternative, he receives Griffin’s BTC for $25,000, and the Bitcoin spot price turns into $25,000.
In the meantime, Brown’s and Quagmire’s orders will stay open.
What’s market depth?
The open orders are packed collectively as purchase and promote orders and pitted in opposition to each other on a market depth chart.

The X-axis on the graph represents the bid (purchase orders in inexperienced) and the ask (promote orders in pink) worth, whereas the Y-axis represents the cumulative market quantity.
