DXY chart: the US dollar index (TVC:DXY) against gold and EURUSD
Open a DXY chart in SuperCharting as TVC:DXY, learn what the dollar index measures and overlay it on XAUUSD or EURUSD with the Compare symbols button.
A DXY chart shows the US dollar index, which measures the dollar against a basket of six major currencies. In SuperCharting you open it as TVC:DXY: press Ctrl + K, type dxy and choose the index. Traders keep it on screen because most of the market's big currency, gold and commodity moves have the dollar on one side of them. This page explains what DXY is made of, how to chart it and how to overlay it on XAUUSD or EURUSD.
What DXY is
DXY is the ICE US Dollar Index. It is a weighted average of the dollar's exchange rate against six currencies, scaled so that it stood at 100 in March 1973. When the index rises, the dollar is gaining on the basket; when it falls, the dollar is weakening.
The standard weights are:
| Currency | Weight |
|---|---|
| Euro (EUR) | 57.6% |
| Japanese yen (JPY) | 13.6% |
| British pound (GBP) | 11.9% |
| Canadian dollar (CAD) | 9.1% |
| Swedish krona (SEK) | 4.2% |
| Swiss franc (CHF) | 3.6% |
Two things follow. First, DXY is mostly a euro index in disguise: with more than half the weight, EURUSD and DXY tend to move in opposite directions. Second, the basket is old and narrow. The Indian rupee, the Chinese yuan and the Mexican peso are not in it, so a rising DXY does not mean the rupee must fall. For that, chart USDINR directly.
Why traders watch it
- Gold. Gold is priced in dollars, so a stronger dollar makes it dearer for holders of other currencies, and gold often (not always) moves the other way. Their link changes over time and breaks down at some turning points.
- Currency pairs. EURUSD, GBPUSD, USDJPY and USDCAD are all part of the basket. DXY gives one line for the dollar's broad direction, so you can tell a EURUSD move caused by the euro from one caused by the dollar.
- Risk and rates. The dollar often firms when investors want safety or when US interest rates rise relative to others. The bond screener compares government yields by country.
- Emerging markets and commodities. A strong dollar tends to weigh on commodities priced in dollars and on emerging-market assets, which is one reason Indian traders follow it.
These are tendencies, not rules. Treat DXY as context for a trade you have already planned on its own chart.
Where the DXY data comes from
TVC:DXY is served from public market data, not from a broker connection. The Data type menu next to the symbol in the chart header shows the exchange and feed serving the chart. This feed gives a few thousand of the newest bars per timeframe, so a daily chart reaches back many years, while a 1-minute chart covers only a few days. Live quotes depend on the feed and the market being open; do not use the chart for execution levels. Gold and currency pairs such as XAUUSD and EURUSD come from broker feeds, described in the forex and gold charts guide.
How to open a DXY chart in SuperCharting
- Press Ctrl + K (or just start typing on the chart) and type
dxy. - Choose TVC:DXY, the US dollar index.
- Pick an interval, for example 1 day.
- Add a trend tool such as two moving averages or Supertrend from Indicators, and mark swing highs and lows with the drawing tools.
- Press Ctrl + S to save the layout.
You can also read a summary without opening the app: the page /symbols/TVC-DXY/ lists the index with its day change, and /symbols/TVC-DXY/technicals/ shows the daily oscillator and moving-average ratings.
How to compare DXY with XAUUSD or EURUSD
SuperCharting has two ways to see two markets together.
Overlay with Compare symbols
- Load XAUUSD on a daily chart.
- Click the Compare symbols button in the top toolbar.
- Type
dxy, choose TVC:DXY. A second line is added on top of the candles. - The price scale changes to percent. The compared line is rebased so both start at the same point at the left edge of what you see, so you compare percentage moves, not prices.
Scroll or zoom and the starting point moves with the left edge. Add more lines by repeating the steps, and press Alt + P to switch the percent scale on or off. The overlay is saved with your layout.
Notice that the compare line is matched to the chart's bars by exact bar time. XAUUSD comes from a broker feed and TVC:DXY from public data, so their daily bars may not carry the same timestamps. If the line looks gappy or broken, switch to another interval or compare with TVC:GOLD, which comes from the same public feed as DXY.
Two charts side by side
Open a two-chart layout. Put XAUUSD in one and TVC:DXY in the other, and under SYNC IN LAYOUT switch Interval and Crosshair on and Symbol off. Move the cursor on one chart and the same moment shows on the other, so you can see where the dollar was when gold turned. See multi-chart layouts. This view keeps DXY's own scale and any indicators you put on it.
A worked example
Take the last 20 trading days, with made-up numbers. DXY falls from 104.0 to 102.0, a change of -1.9%. In the same period EURUSD rises from 1.0800 to 1.1000, +1.9%, and XAUUSD rises from 2,300 to 2,350, +2.2%. On the Compare overlay in percent mode you would see all three lines moving together: the dollar down, EURUSD and gold up. That is the normal pattern. The interesting moments are when it fails, for example gold rising together with the dollar. That says something other than the dollar is driving gold, and it is a reason to look at yields, news or flows rather than to trust the correlation.
Because EURUSD is 57.6% of DXY, a EURUSD chart and a DXY chart are not independent evidence; if the two agree, you have one signal seen twice.
Alerts on the dollar
Right-click a level on the TVC:DXY chart and choose Add alert on DXY at the price. The price alerts guide explains crossing and percent-move conditions. Charts and alerts are for study; past relationships between the dollar and gold do not guarantee future results.
Frequently asked questions
What does DXY stand for?
It is the ticker commonly used for the ICE US Dollar Index. TVC:DXY is the index chart in SuperCharting.
Is DXY the same as USD in my broker?
No. DXY is a calculated index, and you cannot buy it as a spot currency. Brokers offer pairs such as EURUSD, or futures and CFDs linked to the index.
Does DXY include the Indian rupee?
No. The six currencies are EUR, JPY, GBP, CAD, SEK and CHF. Use USDINR for the rupee.
Why does my gold chart show gaps when I compare DXY?
Compare lines are matched by bar time. If the two symbols come from different feeds and their bars start at different times, some points have no match. Try another interval or a symbol from the same feed.
