Reading collection / DeFi Field Notes

Trading costs.

A practical collection about the difference between headline numbers and complete economic outcomes. Quotes, fees, compounding, and maintenance can each change the result of a transaction or strategy.

Choose one reference unit and include the entire route: entry, any repeated actions, and exit. Check whether each displayed figure already includes a particular charge before adding or subtracting it. Keep hypothetical inputs separate from actual quotes. The worked examples here are useful for testing a method; they do not establish that the same prices, fees, or returns are available in a live market.

Use the linked guides below for worked explanations, source references, and connected reading. Keep the glossary open when a term needs a definition, and review the limitations of educational material before applying an example to a real position.
