IN PLAIN ENGLISH
The all-time ceiling and floor, with today's price set against them. Far below the record high can mean it has fallen a long way — or that it once spiked and never came back.
FULL DEFINITION
The highest and lowest price something has been recorded at, and how far today's price is from each.
EXAMPLE
A card with a record high of $3,600 and a record low of $1,200, now at $3,000: (3,000 ÷ 3,600 − 1) × 100 = −16.7% from the high and (3,000 ÷ 1,200 − 1) × 100 = +150% above the low. The marker sits (3,000 − 1,200) ÷ (3,600 − 1,200) = 75% of the way along.
HOW IT'S CALCULATED
The records come from the data source — TickerMint's tracked high and low for a card's printing (since it began tracking that card) and CoinGecko's all-time high and low for a coin — shown in your currency at the latest stored daily exchange rate. A metal has no provider record, so its figure is the highest close in the price history we hold, which begins in 2000 (weekly before the last three months). The percentages are worked out by the app as (price now ÷ record − 1) × 100 in US dollars, so the exchange rate cancels out; the marker is (price − low) ÷ (high − low), held between 0% and 100%. Anything the source doesn't send is left out.
