Description

Bid-Ask Spread measures the difference between the best bid and best ask prices for a particular instrument. It returns both:

• The absolute spread (in quote currency)
• The spread as a percentage of the mid-price

This dual representation allows for cross-instrument and cross-exchange comparison of liquidity conditions.

Details

This metric provides a view of market tightness and liquidity fragmentation. By analyzing how wide or narrow the spread is, traders can quickly identify:

• The most liquid exchange for a given asset
• Which instruments offer the best execution conditions

The percentage spread is especially useful when comparing instruments with different quote currencies (e.g., BTC-USDT vs. BTC-USD vs. BTC-EUR), as it normalizes price scale effects.

Frequently Asked Questions

How is the absolute spread calculated?

• spread = bestAskPrice − bestBidPrice
• This is returned in the quote currency of the instrument.

What does spreadPercent represent?

• It’s the absolute spread divided by the mid-price:
• spreadPercent = (spread / midPrice) × 100
• This normalizes spread data across different pairs.
