A practical research sequence
Start with the question you need to answer: available liquidity, total cost, collateral sensitivity, protocol activity or portfolio exposure. Choose a tool whose input units and data source match that question. Capture the observation time and compare a baseline before changing assumptions.
Each working view links to its methodology and related tools. The public market pages load named providers automatically; local scenario and CSV tools calculate in the browser. Pausing public feeds freezes observations in the current tab, so recheck timestamps before using a retained result.
Interpretation and boundaries
Choose a provider and compare compatible instruments. Read provider coverage, observation times and error states before using a cross-venue result.
The catalogue includes distinct calculations and data views rather than a claim that every measurement is a trading signal. A computed ratio can be numerically correct while its assumptions no longer match the market. Use the source references, check missing fields and retain enough context to reproduce the result.
