Methodology

These pages say where a number on Terminal comes from. Each figure is read from the code that checks alerts and records prices.

• Where prices come from

  Spot prices come from Coinbase public market data, with Kraken when Coinbase is quiet. Candles are 1 minute long. A missing price stays unavailable.

• How often alerts are checked

  Each plan is checked on a schedule read from that plan. A check uses a fresh price. An older price is skipped, and the alert does not fire.

• How an unusual move is measured

  An unusual-move alert compares the price with that coin's own recent moves. The bar is wider for a coin that already swings, and narrower for a quiet coin.

• How alert receipts are recorded

  After an alert, Terminal records the price again at fixed later times. The median is the middle of those recorded changes. A gap stays missing.

• How a why-note is written

  A why-note is a short note on an alert. Code writes every number from stored facts. The words describe what the price did.
