Reading Price
Charts.
Charts are not crystal balls. They show what happened, not what will happen. But learning to read them helps you understand price behaviour, spot trends, and make calmer decisions.

Candlesticks: the building blocks
Most crypto charts use candlesticks. Each candlestick represents a single time period — one hour, one day, one week, depending on your settings. It tells you four things: the opening price, the closing price, the highest price during that period, and the lowest.
The thick body of the candlestick shows the range between open and close. If the price went up during that period, the body is typically green (or hollow). If it went down, the body is red (or filled). The thin lines above and below — called wicks — show the high and low extremes.
A tall green candle means strong upward movement. A tall red candle means strong downward movement. A candle with long wicks and a small body means the price moved around a lot but ended up close to where it started — indecision.
Timeframes
You can view charts at different timeframes. The most common are 1-hour (1H), 1-day (1D), and 1-week (1W). Each candlestick on a 1D chart represents one full day of trading. On a 1H chart, one hour.
Short timeframes (1H, 4H) show fine detail and lots of noise. Prices bounce around constantly. These are used by day traders looking for quick moves. For most people, they create anxiety more than insight.
Longer timeframes (1D, 1W) smooth out the noise. A coin might drop 8% in an hour but finish the week up 3%. If you are buying and holding rather than trading daily, the weekly chart gives you a clearer picture of the actual trend.
A practical rule: use the 1D chart as your default. Zoom out to 1W for the big picture. Ignore 1H and 5-minute charts unless you are actively trading.
Support and resistance
Support is a price level where buying tends to increase. The price drops to a certain point, buyers step in, and it bounces back up. If you see the price hitting roughly the same low three or four times without breaking below it, that level is acting as support.
Resistanceis the opposite. A price level where selling increases. The price rises to a point, sellers take profit, and it falls back. If Bitcoin keeps reaching £52,000 and then pulling back, £52,000 is resistance.
These levels are not magic. They reflect collective human behaviour — people set buy orders at round numbers, at previous lows, at prices where they got burned before. Support and resistance are tendencies, not guarantees. Prices break through them regularly, especially during major news events.
Volume
Volume is the number of units traded during a period, usually shown as bars along the bottom of the chart. High volume means lots of people are trading. Low volume means few are.
Volume matters because it confirms price moves. If Bitcoin jumps 5% on high volume, many participants are driving the move and it is more likely to hold. If it jumps 5% on very low volume, it could just be a few large trades and may reverse quickly.
A sudden spike in volume after a period of quiet often signals the start of a new trend — either up or down. It means something changed and people are reacting.
Moving averages
A moving average is a line on the chart that smooths out price data over a set number of periods. The 50-day moving average, for example, plots the average closing price of the last 50 days. It updates each day as a new data point is added and the oldest is dropped.
The two most commonly referenced are the 50-day and the 200-day moving averages. When the price is above its 200-day moving average, the asset is generally considered to be in an uptrend. Below it, a downtrend.
Moving averages are a way to cut through daily noise and see the direction of travel. They do not predict the future. A coin can be above its 200-day average and still drop 30% next week. But they give you a reference point: “Is the general trend up, down, or sideways?”
What a “dip” actually looks like
People talk about “buying the dip” as if dips are obvious in real time. They are not. What looks like a dip might be the start of a prolonged decline.
On a chart, a dip within an uptrend typically shows as a cluster of red candles followed by a bounce off a support level, with volume increasing on the recovery. The daily chart might show several days of decline, then a green candle with above-average volume, suggesting buyers are stepping back in.
The problem is distinguishing a temporary dip from a trend reversal. A 10% pullback in a bull market is normal. A 10% pullback in a weakening market might lead to another 20% drop. Charts can show you patterns, but they cannot tell you which outcome to expect this time.
A note on limitations
Chart reading is a skill, not a science. It helps you understand market structure and identify trends, but it does not predict the future. Anyone who tells you otherwise is selling something.
Professional traders use charts as one input among many — alongside fundamentals, news, macroeconomic data, and risk management. The chart is context, not a conclusion.
For most UK investors buying and holding, understanding the basics covered here is sufficient. You do not need to learn Fibonacci retracements or Ichimoku clouds to buy your first Bitcoin.
