Metric pair and limit alerts

Goal

Cover two special types: the “Metric pair” alert metric and a limit alert on a specific large order.

1Metric pair

The “Metric pair” alert metric: each metric is built as in the builder — source, field, symbol, market, depth; below are operation, normalization, window, indicator

The Metric pair alert metric joins any two sources into one value right inside the alert condition. Fields in order:

Timeframe — one for both metrics. Exchange — each metric has its own: the “A: Exchange” and “B: Exchange” fields.
Metric A and Metric B — each as in the Metrics Builder: source, field, Symbol (empty — the coin from the condition), Market Type (Spot / Futures), Depth %, BTC pairs. The sources are named as in the builder: “Open Interest (Coin)”, “Open Interest (Total)”, “Options”.
Operation — the same as in the Metrics Builder: Divergence (A − B), Divergence Abs, Composite (A + B), Alignment (A × B), Ratio (A / B), Relative Divergence, Divergence Momentum (ΔA − ΔB), Correlation (ΔA ~ ΔB). Spearman IC and Tail Edge aren't available in alerts.
Normalization — no normalization, Z-Score or Percentile; Normalization window — 100 bars by default; for Correlation — Correlation period.
Indicator — a classic indicator on top of the result, Raw by default.

Then a regular comparison: an operator and the right-hand metric. For Z-Score and Percentile the form shows a hint on what the result means.

The second leg. “Metric pair” does not have it. To compare a coin with the same asset on another exchange — the “Composite metric” indicator with a source that has the “Second leg” field: depth index, aggregated order book, aggregated trades. Options: Same Exchange, Binance spot, Binance futures, Coinbase spot, Hyperliquid futures, Deribit futures. In the alert text it shows as “vs BINANCE_FUTURES”. If the asset does not exist on the second exchange, it will not let you save.

2Limit alert

The “Add Limit Order Notification” form: name, market type, coin, order book side, percentage from price, units, minimum order size and duration

The second alert type. It watches not an indicator value but the appearance of a specific large limit order in the order book. It opens with its own button in the right rail — Limit alerts: the panel lists these alerts, and the green plus opens the form. It isn't in the regular alert list.

Field	What it means
Exchange	Binance, Coinbase (spot only) or Deribit (futures only). No Hyperliquid: limit orders are not collected for it.
Market Type	SPOT or FUTURES.
Coin	From the list.
Ask/Bid Type	Which side to watch: BID — large buy orders below the price. ASK — sell orders above the price.
Percentage from current price	How close to the price the order must sit.
Value Output Type	Coins or USDT.
Minimum order quantity	Order size threshold in the selected units, Coins or USDT. That's how the field is labeled in the form; it means the size of a single order.
Minimum order duration in minutes	How long the order must stand before you get notified.
Name, delay, channel	Same as in a regular alert.

Plan: on the free plan limit alerts are closed entirely — neither assembled nor saved. The same thing is visible by eye with the “Limit orders” layer.

Try it yourself

In the editor pick “Metric pair” as the metric: A — Order Book Bids ($) 1.5%, B — Order Book Asks ($) 8%, operation Ratio.
Look at the “What will happen” line and close without saving.

What you should get. You've built in an alert the same thing as COIN B&A DIFF SMART on the chart, but with your own operation.

Takeaway

“Metric pair” joins two indicators into one value right in the condition, like the comparison mode in the Metrics Builder. Each metric has its own exchange and its own market type. The limit alert is a separate rail button. It watches not a value but the appearance of an order of a given size, closeness to the price and duration, on Binance, Coinbase or Deribit. On the free plan it is closed entirely.

Quick check

How is a limit alert different from an alert on COIN B&A?

It watches one specific large order, not the sum of orders at a depth
It isn't
It's faster

Correct answer: It watches one specific large order, not the sum of orders at a depth
