TerminalGremlin: daily summaries

One file a UTC day (YYYY-MM-DD.csv), one row a coin; all.csv holds every day kept. Format 1.

Columns
  date                The day, in UTC: midnight to midnight.
  coin                The coin, as the site names it.
  group               Why it is on the site: original (the first list), meme, commodity, stock (an index fund or a company's shares, from 21 Oct 2026), or added (the next largest coins).
  hours_recorded      Hours of the day with an order-book reading, 0 to 24. Under 24: the record began or stopped during the day, so every figure covers only part of it.
  open                The first price of the day: the average mid price of Coinbase's spot and OKX's perpetual order books.
  high                The highest of the day's five-minute prices.
  low                 The lowest of the day's five-minute prices.
  close               The last price of the day.
  change_pct          Close against open, in percent.
  volume_usd          US dollars traded on Binance's and OKX's perpetuals: every trade, buys and sells.
  taker_buy_pct       Of that, the share where the buyer was the eager side (a market buy). Above 50: buyers pushed harder.
  oi_close_usd        Open interest at the day's end: US dollars in open futures positions, across the exchanges read then.
  oi_change_pct       Open interest at the end against the start, in percent, over the exchanges read at both.
  funding_annual_pct  The day's average funding as a yearly rate, the exchanges weighted by their open interest. Positive: longs paid shorts.
  liq_long_usd        US dollars of long positions closed by force (forced sells), on OKX, Bybit, Binance and Gate.
  liq_short_usd       US dollars of short positions closed by force (forced buys).
  liq_count           How many liquidations.
  market_cap_usd      Market cap at the day's end, from CoinGecko. Empty for silver and oil, and before 14 Oct 2026.

Good to know
  - Summaries only: one row a coin a day, from public market data recorded by this site.
  - Binance reports at most one liquidation a second for each coin, so liquidation totals are the least that happened.
  - The record has gaps (a collector restarting, an exchange not answering). hours_recorded shows a short day; a gap inside a day is not marked.
  - An exchange or a coin added during a day counts from when it was added.
  - Market caps: CoinGecko.
  - Files are written once, after the day ends, and kept 90 days.
