Calculate a deviation only against a valid reference
For USD-pegged assets, the displayed calculation is provider dollar price minus one, multiplied by 100. A hypothetical price of $0.985 gives a negative 1.5% deviation; $1.008 gives positive 0.8%. The absolute-deviation control can surface either direction. A euro-pegged token priced at $1.10 cannot be assessed against a $1 target, so this page leaves its peg deviation unavailable instead of inventing a foreign-exchange reference.
Counts and supply answer different questions
The peg chart counts asset records after your search filter and before the peg or deviation filters. Ten assets targeting one currency and two targeting another say nothing about their relative total value. Their native supply units are not added together. Use the USD supply momentum or explicitly USD-valued chain screen when you need a compatible supply comparison rather than a count of target labels.
Treat an unusual quote as a lead to investigate
An indicative provider price is not an executable redemption offer. A deviation can differ across venues and trade sizes, and a missing quote means the provider did not supply a usable value. Inspect market liquidity, the issuer’s redemption arrangements and the source receipt before assigning meaning to an outlier. The provider’s backing classification is shown for context, but the observatory does not independently verify reserves or legal claims.
