What are Candlestick Charts and Precious Metal Markets?

Candlestick charts originated in the 18th-century Japanese rice market. Each candle records four prices: open, close, high, and low. In the precious metals market, candlestick charts provide a visual representation of intraday price fluctuations and the balance of power between buyers and sellers for gold or silver. This tool provides daily, weekly, and monthly candlestick data for major contracts on the Shanghai Gold Exchange (SGE), such as Au99.99 and Ag(T+D), eliminating the need to switch between multiple platforms.

Principles and Formulas: Calculating Rate of Return

By connecting the queried closing prices, you can calculate the total rate of return for any holding period:
Rate of Return = (Ending Price - Beginning Price) / Beginning Price × 100%
For example, if gold rises from 450 RMB/gram to 480 RMB/gram, the rate of return = (480 - 450) / 450 ≈ 6.67%. This formula is the most direct way to measure investment returns. In candlestick analysis, combining the trends formed by multiple candles helps determine whether the market is in the early or late stages of an uptrend, assisting in trading decisions.

How to Use: Checking Candlestick Charts

Open the "China Precious Metals Candlestick Charts" tool above. You will see three main areas: asset selection, time range, and the chart area.
In the "Asset" dropdown, select "Gold (Au99.99)" or "Silver (Ag(T+D))". Example: Select Gold.
In the "Interval" dropdown, select "Daily" or "Weekly". Beginners are advised to start with Daily charts.
Set the start and end dates, for example, 2024-01-01 to 2024-06-30, and click the "Search" button.
The chart area will immediately display the candlestick chart. Hovering over a single candle will show the open, high, low, and close prices, as well as the percentage change for that day.

Complete Example: Calculating a 6-Month Return on Gold

Let's look at a practical example. In the tool:
• Select "Gold (Au99.99)" for the asset, "Daily" for the interval, and set the dates from 2024-01-01 to 2024-06-30. Click Search.
• Hover over the first candle (2024-01-02, excluding the New Year holiday) and note the opening price of 480.00 RMB/gram.
• Hover over the last candle (2024-06-28) and note the closing price of 512.00 RMB/gram.
• In the "Return Calculator" area at the bottom right of the tool (if available), enter these two numbers, and the tool will automatically display a rate of return = 6.67%.
• If the tool does not have a calculation area, you can calculate it manually: (512 - 480) / 480 × 100% = 6.67%.
• Interpretation: A 6.67% half-year return exceeds standard bank term deposits. However, the highest price during this period reached 535 RMB (indicated by a red upper shadow), showing significant volatility. Buying at the peak could result in short-term losses.

More Examples: Comparing Silver's Performance

Keeping the same dates, change the asset to "Silver (Ag(T+D))".
• The beginning price is approximately 6,000 RMB/kg, and the ending price is 7,800 RMB/kg.
• Rate of Return = (7,800 - 6,000) / 6,000 = 30%.
• Compared to gold's 6.67%, silver exhibits higher volatility, offering higher potential returns but also higher risks. When making decisions, you can use this tool to switch between assets and compare the historical performance of different precious metals.

Interpreting Results: Understanding Returns and Candlestick Patterns

Return > 10% (Half-year): A strong signal, but you need to confirm if the price is near a chart top.
Return 0% – 10%: A moderate market. Combine with trading volume to judge trend continuity.
Return < 0%: A loss zone. Check if the chart shows consecutive bearish candles or long lower shadows (indicating potential support).
Long real body: Strong one-sided market momentum; Long upper shadow: Heavy selling pressure above; Long lower shadow: Strong buying support below.

Common Mistakes and Pitfalls

Only looking at closing prices and ignoring intraday volatility: The high and low prices of a candle represent market sentiment; the closing price is just the final result.
Mismatched contracts for beginning and ending prices: For example, using the Au99.99 price for the start and the Au(T+D) price for the end. The price difference between the two will cause calculation errors.
Ignoring transaction costs: Precious metal trading involves commission and storage fees. The actual return should deduct these costs; the tool only shows the raw price difference.
Choosing too short a time span: One or two days of candlestick data contain a lot of noise. Look at trends over at least one month.

Frequently Asked Questions (FAQ)

1. What do the red and green colors (or bullish/bearish candles) in the chart mean?: In the Chinese market, red (bullish) means the closing price is higher than the opening price, indicating a price increase. Green (bearish) means the closing price is lower than the opening price, indicating a price decrease. The solid body represents the trading range between the open and close.
2. How much of a delay is there in the queried market data?: This tool uses end-of-day closing prices from the Shanghai Gold Exchange, delayed by one trading day. It is not a real-time quote and is best suited for historical review and analysis.
3. Are the prices displayed in RMB?: Yes. Gold is priced in RMB/gram, and silver is priced in RMB/kg. Both represent domestic spot contract prices.
4. Can I use this to predict future gold prices?: No. Candlestick charts reflect historical trading and do not predict the future. Investment decisions should incorporate fundamentals, policies, etc. This tool only provides historical data for reference.
5. Why does my candlestick chart look different from other trading software?: This may be due to different price adjustment methods (restoration). This tool uses unadjusted raw prices, which may differ from software that applies forward or backward adjustments.
6. How do I export the candlestick data to Excel?: There is an "Export CSV" button above the chart. Click it to download the price data for your selected time period.
