Gold Technical Indicators Explained: RSI, Moving Averages and More

On our home page you will find a box headed “Daily gold & oil technical signals”. It gives a one-word verdict (Bullish, Bearish or Neutral) with four numbers beneath it: RSI (14), 5-day momentum, support and resistance. The terms sound like trader jargon, but the ideas are simple, and knowing them stops you reading more into the box than it can tell you.
This guide explains what each indicator measures, exactly how our site calculates it, how the indicators combine into one signal, and where their usefulness ends. Neither the box nor this article is investment advice.
Where the numbers come from
The indicators use gold’s daily closing prices, in US dollars per ounce, over roughly the last three months, with the live price standing in for today’s close. They refresh about every ten minutes and need at least 22 days of data; otherwise the box shows “Not enough data yet”.
They are called technical because they look only at the price itself, unlike fundamental analysis, which weighs interest rates, the dollar and demand. The Brent oil card next to the gold card uses exactly the same method.
Relative Strength Index: RSI (14)
RSI compares the size of recent gains with the size of recent losses over the last 14 days, on a scale from 0 to 100. It was introduced by the American analyst J. Welles Wilder in 1978 and is one of the best-known technical indicators.
We add up the daily rises over the last 14 changes and divide by 14, do the same for the falls, then divide the average gain by the average loss to get the relative strength (RS). Then RSI = 100 − 100 ÷ (1 + RS). For example, if the up days total 120 dollars and the down days 60 dollars, the average gain is 120 ÷ 14 ≈ 8.57, the average loss 60 ÷ 14 ≈ 4.29, RS is 2, and RSI = 100 − 100 ÷ 3 ≈ 66.7.
- Above 70: “overbought”, meaning the price has risen quickly compared with its recent past.
- Below 30: “oversold”, meaning it has fallen quickly.
- Around 50: gains and losses are roughly in balance.
RSI can stay above 70 or below 30 for weeks in a strong trend, so “overbought” is no reliable sign that a reversal is near. Platforms that use Wilder’s original smoothing instead of a simple average may show a slightly different value.
The 5-day and 20-day moving averages
A simple moving average is the average of a set number of recent closes. It moves because each day the newest price comes in and the oldest drops out. Five days is roughly a trading week, and twenty days roughly a trading month.
What matters is the comparison. When the 5-day average is above the 20-day, recent prices are higher than the month’s average, a short-term upward tilt; the reverse is a downward tilt. For example, closes of 4,050, 4,070, 4,060, 4,090 and 4,080 dollars give a 5-day average of 4,070, so with a 20-day average of 4,010 the short average is on top.
The box does not display the averages, but they feed into the signal, as our pricing methodology notes. Their main weakness is lag: the order only changes once a move is already under way.
5-day momentum
Momentum is the percentage change between the current price and the close five trading sessions earlier, about a week ago. If gold is at 4,040 dollars and was at 4,000 five sessions back, momentum is +1%. To filter out tiny wobbles, it counts as positive only above +0.15% and negative only below −0.15%; anything in between is treated as flat.
Support and resistance
In our box, support is the lowest daily close of the last 20 trading days and resistance is the highest, both in dollars per ounce. Together they mark the band in which gold has closed over roughly a month. Compare them with the current price, now 4,072.10 dollars an ounce, to see whether gold is near the top or the bottom of that range.
Because both use closing prices, the price may briefly have traded beyond them within a session, and a break through either level does not guarantee the move will continue. They are shown for context only and do not count towards the signal.
How the signal is scored
Each of the other three indicators contributes at most one point, positive or negative:
- Moving averages: +1 if the 5-day average is above the 20-day; otherwise −1.
- Momentum: +1 above +0.15%, −1 below −0.15%, 0 in between.
- RSI: +1 below 30, −1 above 70, 0 in between.
The total ranges from −3 to +3. A score of +2 or more shows Bullish, −2 or less shows Bearish, and anything in between shows Neutral. Note that RSI works against the other two: an overbought reading takes a point away, so a very strong rally can appear as Neutral.
| Hypothetical case | Averages | Momentum | RSI | Score | Signal |
|---|---|---|---|---|---|
| 1 | Short above (+1) | +0.8% (+1) | 58 (0) | +2 | Bullish |
| 2 | Short above (+1) | +1.6% (+1) | 76 (−1) | +1 | Neutral |
| 3 | Short below (−1) | −0.6% (−1) | 41 (0) | −2 | Bearish |
| 4 | Short below (−1) | −2.1% (−1) | 26 (+1) | −1 | Neutral |
Limitations, and how to use the box sensibly
- It only looks backwards. It knows nothing about next week’s interest-rate decision or a sudden geopolitical event.
- The window is short. The longest measure is 20 days, so it says nothing about the trend over years.
- It lags and it flips. Averages catch up after a move, and in a sideways market the signal can change often without any real trend.
- The thresholds are conventions. 30, 70 and 0.15% are common choices, not laws of nature.
The re-basing of older futures data to the spot price, described in how to read a gold price chart, does not distort the readings: every price is multiplied by the same number, so RSI, momentum and the order of the averages stay the same.
Treat the box as a thermometer for the market’s mood over recent weeks, not a compass for when to buy. A Bearish signal is no reason to postpone buying a wedding set, and a Bullish one is no reason to rush. As the note under the box says, it is an indicative outlook based on past prices, not investment advice.
Frequently asked questions
Why is your RSI different from the one on a trading platform?
Usually because of the calculation (a simple average here, Wilder’s smoothing on many platforms), the data (futures or spot) or the time the day is deemed to close. The differences are normally small and rarely change the overall picture.
Does Bullish mean the price will rise tomorrow?
No. The signal sums up what the price has done over recent days and weeks. It does not forecast, and it can flip in a single session if the news changes.
If RSI drops below 30, is that a good time to buy?
Not necessarily. Oversold means the price has fallen fast, and it can keep falling. Your needs and budget come first; these indicators are general information, not a recommendation.
Knowing what sits behind that single word lets you use the box for what it is: a quick snapshot of the last few weeks. For other terms you meet on the site, see our gold market glossary.
