The chart
Each point would be one date and one price per troy ounce, returned as a list by the price service. The buttons choose the range. The page draws only what that list contains.
Loading price history.
Ranges
The labels are 1M, 3M, 1Y, 5Y, 10Y and Max. The request uses 1m, 3m, 1y, 5y, 10y and max. One month means the range code 1m. It does not mean this website stored a month of prices itself.
| Button | Range code |
|---|---|
| 1M | 1m |
| 3M | 3m |
| 1Y | 1y |
| 5Y | 5y |
| 10Y | 10y |
| Max | max |
When history is missing
If the price service is not configured, the request fails, or the answer is an empty list, the chart area says history is not available right now. There is no sample line, no saved backup series, and no number typed into this page to stand in for a missing year.
A live spot price on the calculators is a different request. Those pages can show a sample price when the spot feed is down, and they label it Sample. This history page does not do that. An empty history stays empty.
History and melt value
A past price per troy ounce is not the melt value of a ring. Melt value still needs the weight and the karat, as the scrap value guide explains. A higher year on the chart does not mean a buyer will pay that figure for jewelry today. Use the scrap gold calculator for an estimate, and treat it as an estimate.
Questions
Where do the history numbers come from?
From the price service, at the history address, for the range you select. This page does not keep its own list of past prices.
What do the range buttons mean?
1M, 3M, 1Y, 5Y, 10Y and Max ask the service for 1m, 3m, 1y, 5y, 10y and max. The service decides which dates fall in that range.
Why does the page say history is not available?
The request failed, the address is not configured, or the service returned no prices. The page does not fill the gap with a sample series.
Is a point on the chart today’s melt value?
No. A point is a past price per troy ounce from the service. Melt value still depends on weight and karat. Use the scrap gold calculator for that estimate.
Can I use this chart as a forecast?
No. It shows prices the service returned for past dates. It is not a prediction and not a promise of what a buyer will pay.
This is a melt-value estimate, not an appraisal or an offer.
