What a chart pattern is

A chart pattern is a shape that price has made before and that traders have given a name. The shape appears on a chart when price moves in a way that can be seen again and again. Traders draw lines on charts to mark the edges of these shapes, so they can talk about them and watch for them in the future. A pattern describes what price has already done. It does not predict what price will do next.

A shape price has made before

A chart pattern is not a rule. It is a shape that price has made before, and traders have given the shape a name. The name makes it easy to talk about: instead of describing a long decline followed by a bounce and another decline, a trader can say a falling wedge. The name does not make the shape any more likely to appear again, and it does not make the shape a promise.

Patterns can be drawn on any time frame, from a few minutes to many years; this site uses daily bars only. The same shape can appear on a chart of Brent crude, of gold or of any other market. The shape is the thing, not the instrument. A pattern on one instrument does not mean the same pattern will appear on another at the same time.

Why traders draw lines on charts

Traders draw lines on charts to mark the edges of a pattern. A line across the highs of a range marks the top of the range. A line across the lows marks the bottom. These lines are not part of the price; they are drawn by the trader to make the shape easier to see. The lines are a way of talking about the pattern, not a way of changing it.

Lines can be drawn in many ways, and different traders draw different lines for the same price history. That is why a pattern is not a single, agreed shape. It is a shape that many traders recognise, but each trader may draw the lines slightly differently. The lines are a tool for description, not a rule for trading.

Candle patterns and chart figures

A candle pattern is made of a few candles, often two or three. It is a small shape that appears over a short time, such as a day or an hour. A piercing line is a candle pattern made of two candles. A dark cloud cover is another. These patterns are read as signs of a possible turn in the short term.

A chart figure is made of many candles over a longer time, often weeks or months. A triple top is a chart figure. A rising wedge is another. These figures are read as signs of a possible turn over a longer time. The difference is the number of candles and the time they cover, not the idea behind them.

Why most patterns are only clear after the fact

Most patterns are only clear after the fact. A triple top is not a triple top until the third peak has formed and price has broken below the level between the peaks. Before that, it is just a series of highs. A rising wedge is not a rising wedge until the two trend lines have been drawn and price has broken out of them. Before that, it is just a series of higher highs and higher lows.

This is why patterns describe what price has already done. They are not predictions of what price will do next. A pattern can be seen in the price history, but that does not mean it will be seen in the future. The shape is a record, not a forecast.

A pattern is not a promise

Traders often say a break above resistance means price will keep rising. That is not what a chart pattern does. A pattern is a description of what price has already done, not a contract for what it must do next. When a trader buys after a breakout, they are betting that other traders see the same shape and act the same way. If those other traders hesitate, the pattern fails.

The failure is not rare. It happens often enough that experienced traders look for it. They know that a clear pattern attracts attention, and attention can bring early buyers and sellers who then take profit quickly. That profit-taking can push price back the other way, breaking the pattern just when it looked most reliable. The pattern did not lie; it simply described one moment.

A chart figure is drawn neatly, arrows are added, and a target is given. What is left out is the number of times the same figure appeared and nothing followed. A pattern is a way to organise what price did. It is not a promise about what price will do.

What the chart under the heading shows

The chart under the heading is a double top on Brent crude futures. The first high, 57.43 dollars a barrel, came on 2 February 2017 and the second, 56.63, on 12 April; the trough between them was 49.64 on 22 March, a depth of 6.99. The figure counted as formed on 4 May 2017, when a session closed at 48.38, below the trough.

It is the cleaner of the two double tops that rule DT-1 found in ten years across Brent and gold, one on each. It is on the page to show what a pattern looks like on a real chart, with its imperfections: the two highs are not level, and the trough line slopes in the eye of anyone who draws it by hand. The rule measures it and the chart marks what the rule used.

How many were found

Over ten years of daily bars on Brent crude and gold futures the rule found two double tops. That is the whole count. A figure that textbooks draw on every second chart is, under a rule with a 5 ATR trough depth, a rare event: it takes a rise before it, two highs within 0.15 of the trough's depth, a trough at least 5 ATR deep and a closing break below the trough, with the highs 10 to 80 sessions apart.

This page does not rank the double top among the other figures of the site. It says only that written down exactly, it occurred twice on these two series.

The line is only as good as the points it touches

When a trader draws a line across highs or lows, that line matters only if price touched it enough times. One touch is a dot. Two touches make a possible level. Three or more touches make traders take it seriously. The more points that line connects, the more traders will watch it. But each touch also makes the level more obvious, and obvious levels can become crowded.

A crowded level is a place where many stop orders sit. If price approaches and then reverses, those stops are not triggered. If price breaks through, a rush of stops can push it further. The line itself did nothing. It was only a marker. The reaction came from the orders placed around it. A beginner should always ask: how many times did price actually touch this line?

Sometimes a line is drawn through two points that are far apart in time. That line looks clean on a chart, but it may not mean much. Price in between ignored it completely. A good line connects points that price respected repeatedly. A bad line connects whatever the trader wants to see. The difference is visible only when you look at the whole history, not a selected part.

Drawing the pattern too early is the common mistake

A trader sees a few touches and begins to draw a channel or a wedge. They are excited because the shape looks familiar. But a pattern is not confirmed until enough touches happen. If you draw a trendline after two lows, you are guessing. Price may not come back to that line again. The pattern you saw was only a possibility, not a fact.

The temptation to draw early is strong because everyone wants to be ahead of the crowd. But being early on a pattern often means being wrong. Price has no obligation to complete the shape. It can drift sideways, break the line, or reverse entirely. The trader who drew early is then left with a line that no longer fits, and they may redraw it to force a match.

A better order of operations is to wait. Let price touch the line at least three times before drawing it. Then watch what happens at the next touch. If price respects the line, the pattern is still alive. If it breaks through, the pattern is dead. Drawing early does not make the pattern appear sooner; it only makes your analysis less reliable.

A chart figure is bigger than a candle pattern

A candle pattern is made of one, two, or three candles. A piercing line is two candles. A dark cloud cover is two candles. They tell you about a short burst of buying or selling. A chart figure, like a triple top or a wedge, takes many candles to form. It can span weeks or months. The time difference matters because a candle pattern can be over before you finish reading it.

A chart figure describes a longer struggle between buyers and sellers. It shows repeated tests of a level, or a narrowing range, or a slope that is losing steam. That struggle is visible only when you step back. A single candle cannot show you a triple top. It cannot show you a channel. Those shapes need distance to appear.

Beginners often confuse the two. They see a strong candle and call it a pattern. But a candle is a building block. A chart figure is the wall. The wall tells you more about the structure of the market. The candle tells you about one push. Both are useful, but they answer different questions. One is a moment. The other is a movement.

Most patterns are drawn after the move is already underway

Look at any chart and you will see patterns that seem obvious. A triple top stands out clearly because you can see the whole shape. But at the time it was forming, each high was just one high. No one knew if a fourth high would come. The pattern was only clear in hindsight. That is why so many patterns look perfect in old charts and messy in live ones.

A trader who draws a pattern after the fact is not predicting anything. They are describing history. That is useful for learning, but it is not the same as trading. In live markets, the right edge of the chart is always blank. The pattern is incomplete. You are forced to draw lines into the unknown, and those lines may be wrong.

This is the honest part that many signal groups leave out. They show a completed pattern and imply it was obvious at the time. It was not. The trader who actually traded it had to make a decision before the shape was finished. That decision involved risk. A pattern is not a map of the future. It is a sketch of the past.

A pattern on a chart is someone's story, not a law of price

That does not make patterns useless. It makes them tools for describing what has happened, not rules for what must happen next. A pattern can help a trader organise the mess of price history into something that can be discussed. But it is always a simplification, and the chart will not respect it. Price will do what it does, with or without the neat lines someone has drawn.
