Common chart patterns
Chart patterns organise price movements into recognisable shapes that traders use to describe possible continuation or reversal scenarios. Building on the previous lesson about RSI and MACD, this lesson explains common patterns, their limitations and how to interpret them without treating any formation as a reliable prediction.
Reading patterns in context
A chart pattern is a structure formed by successive highs, lows and periods of consolidation. Support describes an area where falling prices have previously attracted buying interest; resistance describes an area where rising prices have previously met selling interest. These are usually zones rather than exact boundaries. Patterns help organise these observations, but their identification can be subjective.
Context matters as much as shape. The same formation may have different implications after a sustained trend than within a sideways market. Timeframe also matters: a pattern on a five-minute chart may sit inside a larger daily consolidation. On MT5, charts across different timeframes can help show this relationship. No pattern guarantees a particular direction or the size of a move.
Common reversal patterns
A double top consists of two peaks near a similar resistance area, separated by a decline. Traders generally regard it as a potential bearish reversal only after price breaks below the intervening low. A double bottom is the reverse: two troughs around support, separated by a rise, with a break above the intervening high used as a confirmation condition. Before that break, either formation may remain a range.
A head-and-shoulders pattern has three peaks: a higher middle peak, called the head, between two lower shoulders. A neckline connects the lows between them. A break below that neckline is commonly interpreted as evidence of a possible reversal from an upward trend. An inverse head-and-shoulders has three troughs and reverses the structure. These formations rarely look perfectly symmetrical, and apparent confirmation can still fail.
Continuation and consolidation
Flags and pennants are short consolidations that follow a relatively sharp price move, often called the flagpole. A flag usually forms a small channel, while a pennant has converging boundaries. Traders commonly interpret a breakout in the direction of the preceding move as a possible continuation signal. However, a consolidation can last longer than expected or resolve in the opposite direction, so the label is not a forecast.
Triangles form as price swings become narrower. An ascending triangle has broadly level resistance and rising lows; a descending triangle has broadly level support and falling highs. A symmetrical triangle has falling highs and rising lows. Rectangles, by comparison, have broadly horizontal upper and lower boundaries. Although some shapes have conventional directional interpretations, price can break either boundary. The eventual direction cannot be known from the shape alone.
Worked example: a double top
Consider a hypothetical EURUSD chart with two peaks near 1.1050 and an intervening low at 1.1000. The pattern height is 0.0050, or 50 pips, because one EURUSD pip is 0.0001. If price breaks below 1.1000, a conventional measured-move projection subtracts that height from the breakout level: 1.1000 − 0.0050 = 1.0950. This is a chart-based reference, not a prediction, guaranteed destination or trade recommendation.
To illustrate exposure, a hypothetical short CFD position of 0.10 standard lot represents 10,000 EUR. Since one EURUSD pip is worth USD 10 per standard lot, it is worth USD 1 at this size. A 50-pip decline would therefore produce a USD 50 gross gain; a 50-pip rise would produce a USD 50 gross loss. These figures exclude spreads, commissions, financing and execution effects. Leverage reduces required margin, not the loss generated by a given price move.
Confirmation and pattern failure
A breakout occurs when price moves beyond a pattern boundary, but a brief crossing may reverse quickly. Some traders distinguish an intrabar break from a candle close beyond the boundary; others observe whether price returns to test the broken area. Neither approach removes uncertainty. A retest may never happen, and waiting for additional evidence can mean observing a substantially different price by the time confirmation appears.
RSI and MACD can add information about momentum, but they also derive from price and do not provide independent proof that a pattern will succeed. Economic announcements can abruptly change market conditions, which connects this topic to the next lesson on fundamental analysis and the economic calendar. CFDs are leveraged products and carry a high risk of loss. Pattern recognition cannot replace an understanding of exposure, trading costs and execution risk.
- Chart patterns describe possible scenarios, not certain outcomes.
- Trend, timeframe and support or resistance provide essential context.
- Breakouts and measured-move projections can fail.
- Leverage magnifies exposure relative to margin; CFD losses can be substantial.
