Candlestick and price patterns: what they're really worth

Patterns are the recurring "words" of the chart: configurations of candles or price that repeat and that traders have learned to recognise. They're useful, but must be handled honestly: a pattern on its own is not a signal. It becomes interesting when it appears in the right place and in the right context. Let's see the most important ones and, above all, how to use them without illusions.

The principle: context before pattern

If you draw a pin bar in the middle of nowhere, it's just a candle with a long wick. If it appears on an important support, in an uptrend, after a pullback, it means something different. Remember this formula:

Pattern + level + trend/context = an idea; the pattern alone = noise.

Candlestick patterns

Pin bar (hammer / shooting star)

A candle with a small body and a long wick (at least two or three times the body) on one side. The hammer has the wick below: price fell and rejected the lows. The shooting star has the wick above: price rose and rejected the highs. It tells of a price rejection.

Engulfing

A candle whose body entirely engulfs that of the previous one, of the opposite colour. A bullish engulfing (after a decline) says buyers took control with force; a bearish one the opposite. It's more significant at an important level.

Doji

Open and close almost equal: a tiny body. It means indecision. After a strong move it can signal a pause; on its own it doesn't tell direction.

Inside bar

A candle entirely contained within the range of the previous: compression. It often precedes an expansion; you can trade the break of the mother candle's high or low.

Price patterns (chart formations)

Double top / double bottom

Price touches the same level twice and is rejected: it forms an "M" (double top) or a "W" (double bottom). The formation is confirmed when price breaks the "neckline" (the middle low of the M or the middle high of the W). The theoretical target equals the height of the formation projected from the breakout.

Head and shoulders

Three highs, with the middle one (the head) higher than the two on the sides (the shoulders). It's confirmed by the break of the neckline, which joins the two lows. It signals a possible exhaustion of a rally. There is also the inverse version, which signals a possible low.

Triangles

• Symmetrical: lower highs and higher lows, price compresses. It usually continues in the direction of the previous trend, but can also break the other way.
• Ascending: equal highs (horizontal resistance) and rising lows. A tendency to break up.
• Descending: equal lows and falling highs. A tendency to break down.

Flags

After a strong move (the pole) price consolidates in a small channel sloping against the trend (the flag), then resumes in the direction of the pole. It's a continuation pattern.

How reliable are they

The honest truth: no pattern always works, and the success rates circulating online are often inflated by selection (the nice cases are remembered, the others forgotten). Some academic studies on technical analysis give mixed results. So:

• Don't enter only because "there's the pattern".
• Always ask: is there an important level? is it consistent with the trend? can I place a short, sensible stop?
• Test the pattern on lots of historical cases (we'll see how in module 4) before trusting it.

A full example with numbers

Look for patterns on a real chart

Look at GBP/USD on H4: scroll back and look for pin bars and engulfings. For each, check the lesson's three questions: is there an important level? is it consistent with the trend? could I have placed a short stop? Mark how many really worked.

How to study them well

1. Pick two or three patterns and ignore the rest. Better to know a few in depth.
2. Collect at least 30 historical examples of each and mark how many worked.
3. Record where they appeared (level, trend, timeframe) to understand in which conditions they work best.
4. Only then try on demo.

In short

• A pattern is information, not a signal: context (level, trend) matters.
• Pin bar, engulfing, doji and inside bar describe rejection, strength, indecision and compression.
• Double tops/bottoms, head and shoulders, triangles and flags are reversal or continuation formations.
• No pattern is always reliable: define the rules beforehand and test them.
• The value lies in the risk/reward ratio and the short stop.

Practical exercise

1. On the EUR/USD H4 chart find 10 pin bars and 10 engulfings. For each note whether it was at a level and what happened next.
2. Calculate in how many cases price went at least equal to the stop in the expected direction before touching it.
3. Write your written rules for recognising a valid pin bar (proportions, position).
