Rules

Conditions worth being told about

Saved against a wallet, because a rule has to belong to somebody — and only that address can read or change it. Nothing here gates a reading.

Once connected, this page holds
conditions drawn from real readings
A news halt, a paused oracle, an oracle over 900s old while the session is open, execution cost above a limit at a given size, or a pool that could not be read. Each names the endpoint it would be evaluated against.
a symbol, or any symbol
Scoped to one of the eight, or left open to all of them.
an action: notify, or log only
There is no Block the trade. Blocking means signing a transaction, nothing here signs one, and an action that claimed to block would be worse than no rule.
not stored: nothing fires yet. This stage stores rules and shows them; no watcher compares a reading against a condition and no notification is sent. Do not stop watching a symbol on the strength of a rule saved here.
one signature, no transaction, no gas
No reading is behind this. The dashboard, stocks, alerts, oracles and pools pages all answer in full with no wallet at all.
