How to read stock charts: a beginner's guide

A stock chart shows what buyers and sellers have actually done. Once you know the handful of things traders look at, any chart from any broker becomes readable in a minute or two.

What a stock chart shows

Every price chart plots time along the bottom and price up the side. The timeframe decides what each bar represents: on a daily chart one bar is one trading day, on a 15-minute chart one bar is fifteen minutes. Day traders mostly watch intraday charts, swing traders the daily chart, and long-term investors weekly or monthly charts.

Below the price you will usually see volume bars, and sometimes indicator panels such as RSI or MACD. Everything on a chart comes from four prices per bar (open, high, low, close) plus volume.

How to read candlesticks

Most traders use candlestick charts because each candle packs those four prices into one shape.

• The body runs from the open to the close. A green (or hollow) body means the price closed higher than it opened; a red (or filled) body means it closed lower.
• The wicks (or shadows) are the thin lines above and below the body. The top of the upper wick is the high of the period and the bottom of the lower wick is the low.
• Long bodies show one side clearly in control. Long wicks show a price that was reached and then rejected.

Three candlestick patterns worth knowing

• Doji: the open and close are almost the same, giving a tiny body. Buyers and sellers ended the period in balance, which can signal indecision after a strong move.
• Hammer: a small body near the top with a long lower wick, appearing after a decline. Sellers pushed the price down but buyers drove it back up before the close.
• Engulfing: a candle whose body completely covers the previous candle's body in the opposite colour. A bullish engulfing after a drop, or a bearish engulfing after a rise, can mark a shift in control.

A single candle is weak evidence on its own. Patterns matter most when they appear at a support or resistance level and are confirmed by the next candle or by volume.

Spotting the trend

The trend is the first thing to identify, because most setups work best in the direction of the trend.

• Uptrend: a series of higher highs and higher lows.
• Downtrend: a series of lower highs and lower lows.
• Sideways (range): price bounces between a roughly flat ceiling and floor.

Check the trend on a higher timeframe too. A pullback on the hourly chart may just be a pause inside a strong daily uptrend.

Support and resistance

Support is a price area where falling prices have repeatedly stopped and bounced, because buyers step in there. Resistance is an area where rising prices have repeatedly stalled, because sellers step in. The more times a level has held, the more traders watch it.

When a level finally breaks, it often switches roles: old resistance becomes new support, and old support becomes new resistance. Support and resistance are also where traders place entries, targets and stop-losses, which is why they matter so much for planning a trade.

Moving averages

A moving average smooths out daily noise by averaging the closing price over a set number of bars. A simple moving average (SMA) weights every bar equally; an exponential moving average (EMA) gives more weight to recent bars, so it reacts faster.

• The 20-day average tracks the short-term trend, the 50-day the medium-term trend and the 200-day the long-term trend.
• Price holding above a rising average is a sign of strength; price below a falling average is a sign of weakness.
• In trends, moving averages often act as moving support or resistance, which is where pullback entries come from.

Volume

Volume is the number of shares traded in each period. It tells you how much conviction is behind a move. A breakout on volume well above the recent average is more convincing than one on light volume. A pullback on falling volume suggests sellers are not very committed. Comparing today's volume with the 20-day average is a simple way to judge it.

RSI (Relative Strength Index)

RSI measures the speed of recent price changes on a scale from 0 to 100, usually over 14 periods.

• Above 70 is commonly read as overbought and below 30 as oversold. In a strong trend RSI can stay overbought or oversold for a long time, so these levels are warnings, not sell or buy signals by themselves.
• A divergence, where price makes a new high but RSI makes a lower high (or the reverse), suggests the move is losing momentum.

MACD

MACD (Moving Average Convergence Divergence) is a momentum indicator built from two EMAs. With the standard settings, the MACD line is the 12-period EMA minus the 26-period EMA, the signal line is a 9-period EMA of the MACD line, and the histogram shows the gap between them.

• The MACD line crossing above the signal line is read as bullish momentum; crossing below is bearish.
• A histogram that grows shows momentum building; one that shrinks shows it fading.

A 6-step checklist for any chart

1. Trend: is it making higher highs and lows, lower ones, or moving sideways? Check one timeframe higher too.
2. Levels: mark the nearest support below the price and resistance above it.
3. Moving averages: is price above or below the 20, 50 and 200-day averages, and are they rising or falling?
4. Momentum: what do RSI and MACD say, and is there a divergence?
5. Volume: does volume confirm the latest move?
6. Plan: decide the entry, the target (often the next level) and the stop-loss (the price that proves you wrong) before you trade. Compare the distance to the target with the distance to the stop: that's your risk-to-reward ratio.
