The Cardano DEX market over a timeframe, per day (per week over a year, per month beyond two years): volume in ADA, settled swaps, makers (distinct trading wallets per day) and trading fees (volume times pool fee), for all DEXes together or one DEX. Returns the totals of the full UTC days of the range, their change against the equally long period before (null when that period is not stored), each period, and the DEXes of the range by volume with their share. The running day and the day our history starts on are marked partial and left out of totals; coverage says which days are counted and where history starts. Use it for "how much traded on Cardano last month", "is volume growing", "market share of Minswap over 90 days".
