Your own expression built from the two sides of the order book. You put it together from three parts:
Compare demand and supply at different distances from price. B&A and DIFF can't do this: there both sides are taken at the same depth.
For example.
The default setup is BID 1.5% − ASK 1.5%. Both sides at the same depth, which is the same as COIN B&A DIFF at 1.5%. A division example: BID 3% ÷ ASK 8% = 0.6 — near bids are 60% of far asks. With division the line is always positive.
| 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. |
| Ask Bid Type (left) | ASK BID DIFF | BID | What to take on the left: asks, bids or their difference. - Want to compare the skew of one depth with the skew of another — DIFF on both sides. |
| Percentage (left) | 1.5 · 3 · 5 · 8 · 15 · 30 · 60% | 1.5% | Depth for the left side. Near depths (1.5–5%) — orders right at price, they get filled first. Far depths (15–60%) — how much money is waiting in the whole band. |
| Operation | − / | − | Subtract the right part from the left, or divide. With division the result is an absolute value — always positive. - Want to know how many dollars bigger one side is — “−”. - Want how many times, regardless of coin size — “/”. |
| Ask Bid Type (right) | ASK BID DIFF | ASK | What to take on the right: asks, bids or their difference. |
| Percentage (right) | 1.5 · 3 · 5 · 8 · 15 · 30 · 60% | 1.5% | Depth for the right side. |
| 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 the data is always for the USDT pair; the parameter 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. |
Metric COIN B&A DIFF SMART. Condition fields:
The same six settings as on the chart. “BTC pairs” appears only when the coin is BTC.
TOTAL B&A DIFF SMART — the same summed over the whole market. The “Total Type” field is added.
DIFF SMART compares the two sides of the order book at different depths. You choose what to take on the left and right (ASK, BID or DIFF), at what depth, and the operation: subtract or divide. Demand at price bigger than supply far above it is an anomaly: the same money moves price up more than down. The alert has the same six fields.
Setup BID 3% ÷ ASK 8% gives…
Correct answer: Bids within 3% divided by asks within 8%
