How to read platinum and palladium charts
Last updated
Searches for a platinum chart, a palladium price history, PL=F or PA=F often treat Taiwan’s spoken “白金” as these two lines, or treat the dollar closes as a recycle board. The charts sit under Global metals on the homepage quotes tab, after the silver line, and again on the international page after the gold and silver charts. The titles are Platinum (PL=F) history and Palladium (PA=F) history. On a wide screen they sit side by side; below 800px they stack. They plot futures closes in USD per troy ounce. The three buttons are three ways of reading closes, not three boards. This page explains windows, the source and gaps. It does not copy or invent any dollar or TWD print.
Two charts, three buttons, all closes
The buttons read 30D, 90D and 1Y. 30D requests period=1M: Yahoo Finance with interval=1d and range=1mo, daily closes. 90D is period=3M, interval=1d, range=3mo, still daily closes. 1Y is period=1Y, interval=1wk, range=1y, so the points are sparser. It is not every trading day of the year. These windows are not clipped again to exactly 30, 90 or 365 calendar days; the window is that Yahoo range. The weekly 1Y line is Yahoo’s interval=1wk. It is not the gold/silver ratio’s later downsample of paired daily closes on 3Y and 5Y. The homepage and the international page share this chart component. Platinum calls /api/platinum-history. Palladium calls /api/palladium-history. The first load on both is 1M. Each chart loads on its own: one can show Insufficient data while the other still draws.
Each point is that bar’s close, not the open, high or low, and not a candlestick. The readout is the close under the pointer. Times use Taipei. These three windows show the date; 1Y also shows a two-digit year. If the last close is greater than or equal to the first, the line uses the up color. Neither chart has the homepage History tab’s open, high, low or period-change panel, and neither has a 14-row table. The history payload does include stats: open is the first close in the window, and high and low are the highest and lowest of those closes, not the session open, high and low. The chart does not draw that panel. Open, high and low on the metals table are the live row. Do not subtract them from the line.
The symbols are PL=F and PA=F, and gaps stay empty
Platinum is PL=F and palladium is PA=F, from the Yahoo Finance chart API. The history source string is the exchange name plus “PL futures via Yahoo Finance,” or “PA futures via Yahoo Finance.” If Yahoo sends exchangeName, that name is used. If it omits the exchange, the fallback word for these two symbols is NYMEX, and the currency is USD. That source string is not printed under the chart. The accessible name is fixed as NYMEX platinum futures and NYMEX palladium futures; it does not rewrite itself from Yahoo’s exchange field. The note under platinum says it is a PL futures reference (Yahoo ticker PL=F) in USD per troy ounce, and that missing sessions are omitted, never filled in. The palladium note says PA futures reference, same unit, same gap rule. The title already shows PA=F. A missing or invalid close is dropped. Nothing is interpolated. When the period changes, only finite closes greater than zero are kept. Fewer than two points shows Insufficient data. While the next window loads, the panel says it is loading historical data. If the source fails, that panel stays on insufficient data. No second line is invented.
A request that is not 1M, 3M or 1Y — for example 1D, 1W, 3Y or 5Y — falls back to 1M. There is no 5-minute or 30-minute platinum or palladium chart. The buttons call /api/platinum-history and /api/palladium-history only, so the symbols stay PL=F and PA=F. A separate /api/metals-history treats PT=F as an alias and then requests PL=F, because Yahoo does not list PT=F. XPT=F is not an accepted history symbol. If the live card switches to a public spot print because its source is limited, platinum becomes XPT/USD named Platinum spot reference, and palladium becomes XPD/USD named Palladium spot reference. The venue reads OTC SPOT, and open, high, low and the change stay blank. The history lines stay on PL=F and PA=F. They are not redrawn as spot lines, and the spot print is not written into a missing futures point. On a futures row, the live venue is Yahoo’s exchangeName. If that field is empty, the live fallback word for every metal is COMEX. That is a different fallback from the history source, which uses NYMEX when the exchange name is missing. How the two prints differ is in Gold spot vs futures.
Spoken “白金” is not these two lines
In Taiwan, “白金” can mean platinum (stamps such as PT, Pt950, Pt900, Pt999), white gold (still a gold alloy, often K, 750, 585), or be confused with silver. These two charts plot only PL=F and PA=F futures closes in USD per troy ounce. White gold is not priced from this line, and palladium is not another name for platinum. How to separate the names is in Platinum, white gold, and silver. Jewelry and recycle estimates handle gold purities only. Do not drop PL=F or PA=F into the gold-qian formula.
The silver chart is SI=F, with the same 30D, 90D and 1Y buttons, from /api/silver-history, and its note says COMEX silver. How to read it is in How to read the silver price chart. The homepage History tab’s 1D, 1W, 1M, 3M and 1Y, plus the range stats and the 14-row table, are GC=F only. 1D is 5-minute closes and 1W is 30-minute closes. Platinum and palladium have neither button. Gold on the international page also offers only 30D, 90D and 1Y, but that line is GC=F. How to read it is in How to read the gold price chart. The gold/silver ratio is a gold close divided by a silver close, not platinum divided by palladium. The jewelry page’s theoretical buy is TWD per qian, gold only, and it also has 3Y and 5Y. These two charts are not a shop, bank, recycler or ETF board. If the source is unavailable, no price is invented. The two lines are two metals. Do not subtract them into a spread.
HOW TO
Read platinum and palladium history on this site
Confirm PL=F and PA=F dollar closes, then pick 30D, 90D or 1Y. No prices in these steps.
- Find the pair, not the gold History tabThe charts sit on the homepage quotes tab, under Global metals and the silver line, and on the international page under the gold and silver charts. The titles are Platinum (PL=F) history and Palladium (PA=F) history. The History tab is gold GC=F.
- Keep the two symbols apartOne chart is PL=F and the other is PA=F. The note says a futures reference in USD per troy ounce. It is not TWD per qian and not a spoken “白金” recycle board.
- Pick a window on each chart30D and 90D are daily closes (1d, ranges 1mo and 3mo). 1Y is a weekly close (1wk, range 1y). There is no 1D or 1W. Each chart switches on its own.
- The readout is a closeThe line and the readout are closes. Open, high and low on the metals table are a separate live row. These charts have no open or range-stat panel.
- Leave gaps emptyMissing closes stay missing. If a live card switches to XPT/USD or XPD/USD, the charts stay on PL=F and PA=F. Do not subtract silver SI=F, gold GC=F, the ratio, or the jewelry TWD theoretical buy.

Platinum and palladium chart FAQ
What do these charts show?
One close line each. Platinum is PL=F and palladium is PA=F, both in USD per troy ounce. The readout is the close under the pointer. They are not candlesticks, and they have no open, range high, range low, or 14-row table.
Which contract and source?
Yahoo Finance chart series for platinum futures PL=F and palladium futures PA=F. If Yahoo omits the exchange name, the history source falls back to NYMEX. That string is not printed under the chart; the accessible name always says NYMEX. A live row that switches to XPT/USD or XPD/USD does not switch the history line. The on-page charts do not request PT=F. A separate endpoint treats PT=F as an alias for PL=F.
What do 30D, 90D and 1Y mean?
30D is the 1M daily close (interval 1d, range 1mo). 90D is the 3M daily close (range 3mo). 1Y is the 1Y weekly close (interval 1wk, range 1y). There is no 1D or 1W. Any other period falls back to 1M.
Is this a white-gold recycle, shop or bank board?
No. Spoken “白金” can mean platinum, white gold, or be confused with silver. These charts are also not silver SI=F, not gold GC=F, not the gold/silver ratio, and not the jewelry page’s TWD-per-qian theoretical buy. Missing points stay empty. An unavailable source does not get an invented price.
