For example, if you sell through the book down to 50 basis points away from the best-bid/best-ask, LWAP calculates the average execution price for that trade. ## OpenAPI ````yaml get /depth/lwap openapi: 3.1.0 info: title: spot-analytics version: '2' servers: - url: https://api.amberdata.com/markets/spot/analytics security: - sec0: [] paths: /depth/lwap: get: summary: LWAP description: >- Liquidity Weighted Average Price (LWAP) represents the average execution price achieved when trading through all resting orders in the order book (sweeping the book), up to a specified depth.
