Candlestick charts are the standard way to display price in crypto and most other markets. They pack a lot of information into a small space, which makes them intimidating at first. The good news is that you need only a handful of ideas to read them usefully, and those same ideas sit behind every technical trade signal, including the ones SignalEye sends.
Anatomy of a single candle
Each candle summarises trading during one period: one minute, one hour, four hours, one day and so on. It shows four prices:
- Open: the first traded price of the period.
- Close: the last traded price of the period.
- High: the highest price reached.
- Low: the lowest price reached.
The thick part, the body, spans from open to close. If the close is above the open, price rose during the period and the candle is usually drawn green (sometimes hollow or white). If the close is below the open, price fell and the candle is usually red (or filled). The thin lines above and below the body are the wicks (or shadows); their tips mark the high and the low.
| Candle shape | What happened in the period |
|---|---|
| Large green body, small wicks | Buyers in control from open to close |
| Large red body, small wicks | Sellers in control from open to close |
| Long lower wick, small body near the top | Price was pushed down, then bought back up: rejection of lower prices |
| Long upper wick, small body near the bottom | Price was pushed up, then sold back down: rejection of higher prices |
| Tiny body, wicks on both sides | Indecision: neither side won the period |
A single candle tells you about one period's tug-of-war. It becomes meaningful only in context: where it formed and what came before it.
Timeframes change the picture
The same market looks completely different on different timeframes. A sharp drop on the 5-minute chart may be a barely visible wick on the daily chart. As a rule of thumb:
- Lower timeframes (1m to 15m) show more detail and more noise. Setups form and fail quickly.
- Middle timeframes (1h to 4h) balance detail and reliability and are popular for swing trades lasting hours to days.
- Higher timeframes (daily, weekly) show the dominant trend and the most important levels.
A common habit is to check one timeframe higher than the one you trade, to make sure you're not buying straight into a major level. Every SignalEye signal states its timeframe, for example "4h", so you know which chart it comes from.
Reading trend with highs and lows
The simplest definition of trend uses swing points, the local peaks and troughs where price changed direction:
- Uptrend: higher highs and higher lows. Each pullback stops above the previous one.
- Downtrend: lower highs and lower lows.
- Range: highs and lows roughly level, price moving sideways between two zones.
When an uptrend makes a lower low for the first time, that's called a break of structure. It doesn't guarantee a reversal, but it tells you the pattern that defined the trend has failed. Many traders also use a moving average as a quick trend filter: price above a rising average suggests an uptrend. Our RSI and EMA guide covers that in detail.
Support and resistance
Support is a price zone where falling price has repeatedly stopped and turned up. Resistance is a zone where rising price has repeatedly stalled and turned down. They exist because traders remember prices: people who missed a move place orders near where it started, and people stuck in losing trades sell when price returns to their entry.
Practical tips for drawing them:
- Think in zones, not exact lines. Wicks often poke slightly through a level.
- Levels with several clear reactions matter more than ones touched once.
- Levels from higher timeframes matter more than ones from lower timeframes.
- After a clean break, roles often flip: old resistance becomes new support, and vice versa. A "retest" of a broken level is a classic entry location.
Candles at key levels
Candle patterns are most informative when they appear at a level you already care about. A few that are worth knowing:
Rejection wicks (pin bars)
A candle with a long wick into a level and a close well away from it shows that the market tested the level and refused it. A long lower wick at support suggests buyers are defending it.
Engulfing candles
A body that completely covers the previous candle's body in the opposite direction, for example a large green candle after a small red one at support, shows a decisive shift in control for that period.
Breakout candles
A strong, full-bodied candle closing beyond resistance, ideally on higher volume, suggests real demand. A breakout that immediately falls back inside the range, a "failed breakout", often leads to a sharp move the other way.
Don't memorise dozens of named patterns. Ask the same question each time: who won this period, at this level, and by how much?
Volume
Volume bars under the chart show how much traded in each period. Moves on rising volume have more participation behind them than moves on fading volume. Volume figures vary between exchanges, so treat them as a relative guide on the exchange whose chart you're reading.
Putting it together: a reading routine
- Zoom out. On a higher timeframe, what's the trend and where are the big levels?
- Mark the levels. Draw the nearest support and resistance zones on your trading timeframe.
- Read structure. Higher highs and lows, lower highs and lows, or a range?
- Watch the level reactions. What do the candles do when price reaches a zone?
- Check indicators as confirmation, not as the main reason.
- Plan before entering: where you enter, where the idea is wrong (stop loss) and where you take profit. See entry, stop loss and take profit explained.
Common beginner mistakes
- Reading one candle in isolation. Context beats any single pattern.
- Drawing too many lines. If everything is a level, nothing is.
- Switching timeframes to find a reason to trade. Pick your timeframe first.
- Ignoring the close. Intraperiod moves can reverse; the close is what the period "decided".
- Trading without a stop. Charts give probabilities, never certainties.
How this connects to signals
When SignalEye's AI reads a chart, it does essentially what's described above: it judges trend and structure, finds support and resistance, looks at how candles behave there and checks RSI and EMA. Learning to read the chart yourself lets you check each signal's reasoning against the chart instead of trusting it blindly, which is exactly how signals should be used.
