A worked distinction
If an exchange last trade briefly moves while the oracle remains unchanged, a chart-based collateral value and the protocol’s risk calculation can diverge. The reverse can occur when the reference updates before the chart refreshes.
What to verify in your own analysis
Identify the asset feed, denomination and deployment rules. A calculator with a manually entered price models that input; it does not monitor the actual oracle or execute a protective transaction.
Write down the market or protocol identifier, units, observation window and data source before comparing outputs. Keep unavailable values distinct from zero. Capture a baseline and change one assumption at a time so the resulting difference can be explained.
