Learn hubBlogLearn COIN B&A DIFF: the difference between bids and asks as one line per depth.
The difference between bids and asks at each depth. Formula: bid − ask, in millions of dollars.
It's COIN B&A collapsed into one line per depth.
The same order book skew, but as one number. You can put a threshold on a number instead of watching two lines.
For example.
| Field | Options | Default | What it changes |
|---|---|---|---|
| Market | SPOT Futures | SPOT | Whose order book to count: the spot or the futures market. SPOT or FUTURES in the pane legend. - Want orders from people buying the coin itself — SPOT. - Want orders from people trading with leverage — FUTURES. On Coinbase, Hyperliquid and Deribit the switch does nothing: Coinbase is spot only, Hyperliquid and Deribit are futures only, the value is set by the exchange itself. |
| BTC pairs | ALL USDT only | ALL | Works only on Binance and only for BTC. ALL or USDT ONLY in the legend. ALL — the sum of three pairs: BTCUSDT + BTCUSDC + BTCFDUSD. USDT only — only the BTCUSDT pair. For other Binance coins, data is always for the USDT pair; the input changes nothing. Does nothing on Coinbase and Hyperliquid: Bitcoin has one pair there. On Deribit too: the two BTC contracts are not added together. - Want all of Binance's Bitcoin — ALL. - Want to compare with a source that counts only BTCUSDT — USDT ONLY. |
| Exchange | Chart Binance Coinbase Hyperliquid Deribit | Chart | Which exchange to take data from: Chart — the same one as the chart. Binance — spot and futures, USDT pairs. Coinbase — spot only, USD pairs. Hyperliquid and Deribit — perpetual futures only, USDC pairs. The list holds only exchanges where the coin trades. Without a subscription there is no field. - Want to compare one coin across exchanges — add the indicator several times and pick a different exchange in each. |
By default one depth is visible — 3%. Turn on the other depths in the Styletab: tick the line you need.
Metric COIN B&A DIFF. Condition fields:
“BTC pairs” appears only when the coin is BTC.
TOTAL B&A DIFF — the same summed over the whole market. The “Total Type” field is added.
B&A DIFF = bid − ask at each depth. Above zero — more bids, below — more asks. Color follows the sign. It's COIN B&A collapsed into one line. Depths are turned on in the “Style” tab the same way.
COIN B&A DIFF = −4 at 3% depth means…
Correct answer: Within 3% there are $4M more asks than bids
DIFF at 1.5% = +20, DIFF at 8% = −60. What does it mean?
Correct answer: More bids near the price, more asks further out
