Chart pattern analysis does not always clearly indicate future price trajectory, especially in the case of bilateral patterns. When traders identify a familiar chart formation, they often try to predict where the price will go next. However, some patterns only signal the potential for a strong price move. The direction becomes clear only after the price breaks out of the pattern.
This article focuses on bilateral trading patterns. Since these patterns reflect market uncertainty, traders usually wait for a breakout before entering a trade. We will examine the main types of bilateral patterns, their key differences, and practical trading strategies.
The article covers the following subjects:
Major Takeaways
- Bilateral patterns are chart patterns that do not reveal the price direction in advance. They occur during periods of uncertainty, when buyers and sellers are evenly matched, and the price often moves within a narrowing range. Traders wait for an upward or downward breakout before opening positions.
- Reversal patterns signal a possible trend change, while continuation patterns suggest that the current trend may resume after a pause. Bilateral patterns do not indicate a specific direction: the price can break out either way. However, some patterns may still suggest a possible price direction.
- A Symmetrical Triangle pattern consists of two converging trend lines, and the price can break out in either direction. An Ascending Triangle has a horizontal upper boundary and a rising lower boundary, making an upward breakout more likely, though not guaranteed. A Descending Triangle has a horizontal lower boundary and a declining upper boundary, so a downward breakout is generally more likely, but an upward breakout is also possible.
- Open a trade only after a confirmed breakout. Wait for a candlestick to close beyond the pattern’s boundary, using increased volume as additional confirmation. Enter in the breakout direction and place a stop-loss order beyond the opposite boundary or at the nearest extreme. The target is often based on the pattern’s height, measured from the breakout point. To reduce the risk of a false breakout, wait for a retest of the boundary. Set the risk per trade according to your strategy and acceptable loss.
What Are Bilateral Chart Patterns?
Bilateral patterns are chart formations that appear during periods of market uncertainty, when neither buyers nor sellers have a clear advantage. The price often moves within a contracting Triangle or Wedge, reflecting the battle between bulls and bears. Such patterns can lead to a reversal or a continuation of the current trend. The outcome depends on which direction the price breaks out. Therefore, they can act as reversal or continuation patterns.
Sometimes, a pattern forms after a sharp price movement, as the trading range narrows and volume declines. While the price remains within the pattern, the direction of the next move is uncertain, so traders wait for a breakout. An upside breakout may signal stronger buying pressure and the start of a bullish trend, while a downside breakout may indicate increasing selling pressure. Thus, bilateral chart patterns mainly reflect market uncertainty and the potential for a move in either direction.
Bilateral vs Reversal vs Continuation Patterns
Reversal patterns, such as the Head and Shoulders and Double Top, indicate a possible trend reversal. For example, following an uptrend, they may signal a shift to a downtrend. Inverse Head and Shoulders and Double Bottom patterns, conversely, indicate a possible increase after a decline. Continuation patterns like Flags and Pennants suggest a revival of the prevailing trend and typically occur after a pause or correction.
Bilateral chart patterns are characterized by the possibility of a breakout in either direction. The same pattern can signal either a trend reversal or a continuation, depending on the breakout direction and broader market context.
For example, a Symmetrical Triangle can break out in either direction, although it is often expected to continue the existing trend. When trading these patterns, traders therefore wait for a confirmed breakout instead of trying to predict the direction in advance.
Types of Bilateral Chart Patterns
The most common bilateral chart patterns include the Symmetrical Triangle, the Ascending Triangle, and the Descending Triangle. These patterns are characterized by a narrowing trading range, which is often accompanied by decreasing trading volume. Each pattern has its own structure and distinctive formation characteristics.
Symmetrical Triangle
A Symmetrical Triangle is a chart pattern formed by two converging trend lines. The upper line connects a series of lower highs, while the lower line connects a series of higher lows. The price moves between them, and the range of price fluctuations gradually narrows.
Typically, this pattern forms as trading volume declines, reflecting a decrease in market activity. A breakout can occur in either direction. If the price breaks through the upper boundary, especially amid rising volume, this may serve as a buy signal. A breakout below the lower boundary may indicate a selling opportunity.
The potential price target is often estimated by measuring the pattern’s height and projecting it from the breakout point. To reduce the risk of a false breakout, traders typically wait for a candlestick to close outside the pattern rather than reacting to a brief move beyond its boundaries.
Ascending Triangle
An Ascending Triangle is a chart pattern with a bullish bias. Its upper boundary is formed by a horizontal resistance level, while the lower trend line slopes upward and connects a series of higher lows. The pattern suggests that buyers are becoming more active: they buy on dips, gradually pushing the price toward the resistance level.
This pattern is more likely to result in an upward breakout than a Symmetrical Triangle, but the move is not confirmed until the price breaks above the resistance level. If selling pressure increases at resistance, the price may reverse and move lower. Trading volume often declines as the pattern forms but can rise sharply after a confirmed breakout.
Descending Triangle
A Descending Triangle is the opposite of an Ascending Triangle. Its lower boundary is defined by a horizontal support level, while its upper line slopes downward and connects a series of progressively lower highs.
As the pattern develops, each rebound from support falls short of the previous high, suggesting growing selling pressure. This gives the Descending Triangle a bearish bias.
At the same time, a Descending Triangle can break out in either direction. If support holds or a downside breakout quickly fails and the price returns to the pattern, an upward move may follow. However, a downside breakout is generally considered more likely. Breakouts from a narrowing range are often accompanied by a significant increase in volume.
A Descending Triangle can emerge in both an uptrend and a downtrend. In a bull market, it may signal a potential reversal, while in a bear market, it may indicate that the decline is likely to continue. Candlestick patterns near the Triangle’s boundaries can provide additional confirmation. For example, a long lower wick near support suggests that selling pressure has weakened, potentially reducing the likelihood of a downward breakout.
How to Trade Bilateral Chart Patterns
Trading these patterns requires an understanding of the basics, clear rules, and consideration of fundamental factors that may affect market volatility. Each pattern has its own characteristics:
- For a Symmetrical Triangle, a signal occurs when the price breaks through one of the boundaries, and the candlestick closes beyond it. A stop-loss order can be placed beyond the opposite boundary or at the nearest swing high or low. Set the target based on the pattern’s height, measured from the breakout point. Higher trading volume can provide additional confirmation. After a retest of the broken boundary, consider entering or adding to a position in the breakout direction.
- Ascending Triangle: Consider entering a long position after the price breaks above resistance. Place the stop-loss below the latest low within the pattern and set a take-profit order at a distance equal to the Triangle’s height. Higher trading volume strengthens the signal. You can also enter after a retest of the broken level. If the breakout turns false, it is best to refrain from trading.
- For a Descending Triangle, consider opening a short position after the price breaks below support and the move is confirmed. Place the stop-loss above the most recent swing high and set the take-profit below the breakout point at a distance equal to the pattern’s height. Higher trading volume may confirm the breakout. If the price briefly breaks through the boundary and then reverses, the breakout may be false, so it is best not to enter the trade.
In all cases, do not open a position until the breakout from the pattern is confirmed. Use a stop-loss order to limit losses and set a take-profit order in advance. Candlestick patterns can provide additional signals, but the breakout of a level remains the primary indicator. In a sideways market, it is especially important to wait for confirmation.
Before placing a trade, assess the risk-to-reward ratio. For example, a trader may aim for a ratio of 1:2 or higher, depending on their strategy. Also consider the trend on the higher time frame. If a bilateral pattern forms during an uptrend, an upward breakout and trend continuation may be more likely. In a downtrend, a downward breakout may be more probable. However, neither scenario is guaranteed.
If the price is trading sideways, you can skip the trade or reduce your position size. It is useful to test your strategy on a demo account and evaluate its results before trading with real money.
Conclusion
Bilateral chart patterns are technical analysis patterns that help traders respond to a confirmed signal rather than trying to predict the price direction in advance. After a breakout, you can determine an entry point and develop a trading plan. It is crucial to set stop-loss and take-profit orders beforehand and take trading volume into account. At the same time, false breakouts remain one of the main challenges, so it is essential to adhere to your risk-reward ratio.
These patterns help traders navigate the uncertainty of sideways markets, but they do not ensure profitable trades. Studying charts and gaining practical experience allow traders to understand bilateral chart patterns better and use them more effectively alongside other technical analysis tools.
