How the ratio is calculated.
A plain-language walk-through of what BitClock's ratio measures and where it comes from. This page describes the metric and how it is measured — it is not trading guidance, and it does not tell you what to do at any given reading.
In plain English: a live order book holds resting sell orders (asks) stacked above the current price and resting buy orders (bids) below it. BitClock measures the size on each side in a band around the live price and divides ask depth by bid depth — one number for how the book is stacked right now. A reading of 1.0 means the two sides inside the band are equal; above 1.0 the ask side is bigger, and below 1.0 the bid side is bigger. Everything below is simply how that one number gets measured.
Real resting orders, not trade history
BitClock reads live resting limit orders straight from the exchange's public order-book feed — actual bids and asks sitting on the book, not a log of trades that already happened.
Ask depth over bid depth
Resting ask depth above the current price is measured against resting bid depth below it, within a band around the live price. The result is a single ratio: how the book is stacked at this moment.
One number, continuously updated
At 1.0 the two sides are equal; above 1.0 the ask side is bigger, below 1.0 the bid side is bigger. BitClock shows you the number — what you do with it is yours to decide.
