Bid-Ask Spread Percent
Spread, one of the most common measures of liquidity and transaction costs, is the difference between the price that buyers are bidding at and the price that sellers are asking for. A large spread indicates disagreement between market participants on price and lends to inefficiencies in the market.

Spread is normally calculated using the prices listed at the top of the book— that is, comparing the highest bidding price and the lowest asking price. There are many variations on spread in the literature, such as an effective spread that only uses market candle data and taking into account a degree of orderbook depth. However, here we stick to the classical formulation of spread.
Spread, the difference between the quote asset’s ask and bid price, can be presented raw or as a percentage of a reference price. Typically this reference price is the midpoint between the bid and asking price. Here we represent it as a percentage of the mid price.
We offer the bid-ask spread over 1m, 1h, and 1d intervals. Each of these metrics represents the average bid-ask spread over the interval of time.
