A chart is a picture of price over time. The word comes from the Latin carta, meaning paper. On a trading platform, the chart is drawn with time along the bottom and price up the side. Each point on the line is the price at that moment. A timeframe is the amount of time each point or candle covers. A one-minute chart shows one point per minute. A daily chart shows one point per day.

The same market looks different on each timeframe. On a one-minute chart, the line jumps up and down many times in an hour. On a daily chart, that same hour is a tiny mark. Neither chart is more true. They simply answer different questions. A short timeframe answers what is happening right now. A long timeframe answers what has been happening for weeks or months.

Beginners often switch between timeframes without a reason. They see a fall on the five-minute chart and panic, then look at the daily chart and feel calm again. The chart did not change. Only the view changed. Pick one timeframe for your decisions and use a second only to check the first. Write both down before you look at any chart.

An indicator is a calculation drawn from past prices. The word comes from the Latin indicare, to point out. On a platform, an indicator appears as a line or a set of lines below or over the price chart. A moving average (MA) is the average price over a chosen number of candles. If you set it to 20, it adds the last 20 closing prices and divides by 20. The line moves as new candles form.

The Relative Strength Index (RSI) runs from 0 to 100. It compares the size of recent gains with recent losses. A reading above 70 is often called overbought, and below 30 oversold. These words describe the calculation, not a command to buy or sell. The MACD uses two moving averages and a histogram to show when they pull apart or come together. Bollinger Bands place a line above and below a moving average, widening when price moves more and narrowing when it moves less.

Each indicator is a different way of smoothing the same price data. None of them knows the future. They can help you see a trend or a pause, but they can also give a signal that fails. The usual mistake is to stack five indicators that all say the same thing and treat that as certainty. It is not. Use one or two, and learn what they look like when they are wrong.

A currency pair such as AUD/USD is an exchange rate. It tells you how many US dollars one Australian dollar buys. Around 0.6640, one Australian dollar buys about 66 US cents. Gold (XAU/USD) is quoted in US dollars per troy ounce. It moves with different forces: central bank buying, inflation expectations and the US dollar itself. Its daily range is often larger than a currency pair's, so the same position size carries more risk.

Crypto CFDs and index CFDs are contracts for difference. You never own the bitcoin or the shares. You agree to exchange the difference in price when the contract closes. That means you can go short as easily as long, but you also pay financing if you hold overnight. Index CFDs track a basket of shares, such as the ASX 200. They move with company earnings and interest rates, not with two countries' trade flows.

Each instrument has its own trading hours, its own typical spread and its own margin requirement. Gold and crypto CFDs often trade nearly around the clock. Index CFDs follow the exchange hours. A strategy that works on AUD/USD may fail on bitcoin because the volatility and the costs are different. Before you trade any of them, check the contract specifications on your platform. The numbers vary between brokers.

A chart is a record of prices that were matched. It is not a record of intent. Every candle on AUD/USD near 0.6640 marks a trade that happened, and nothing about the reasons behind it survives on the screen. Two identical candles can sit in the same place on two different days and mean opposite things, because the buyers and sellers who made them are not visible.

The same limit applies to indicators. A moving average, RSI or MACD is arithmetic done on past prices, so it describes what has already occurred. It does not know about an order sitting in a bank's system, a central bank comment, or a position being closed for reasons unrelated to the chart. When a level holds, the chart shows that it held, not why.

This is the point in the course where expectations are usually corrected. A reader who expects a tool to say what happens next will keep adding tools, and the screen will keep getting busier without getting clearer. The honest use of a chart is narrower: it shows where price has been, how fast it moved, and where it paused. Everything built in the rest of this level rests on that narrower claim.

The practical consequence is that a chart is used to plan, not to predict. Levels, sessions and costs are chosen in advance, and the chart is then read against them. A plan that needs the chart to be right is not a plan.
