Expanding Triangle Pattern

The Expanding Triangle Pattern is a technical analysis tool used in forex trading to identify potential breakout points in the market. It was first introduced by Robert D. Edwards and John Magee in their book “Technical Analysis of Stock Trends,” published in 1948.

What is the Expanding Triangle Pattern?

The Expanding Triangle Pattern is formed by two converging trendlines, with one being a horizontal resistance level and the other being an upward sloping support level. As the pattern progresses, the distance between the two trendlines expands, creating a triangle shape on a price chart.

The strategy behind the Expanding Triangle Pattern is to identify potential breakout points in the market and trade in the direction of the breakout.

Some key points to support the effectiveness of this strategy include:

  • The pattern is often seen as a continuation of a trend, meaning that it is likely to continue in the same direction as the previous trend.
  • The expansion of the triangle indicates increasing volatility in the market, which can be a sign of a potential breakout.
  • The pattern often leads to a strong move in the direction of the breakout, providing traders with an opportunity to enter the market with a high probability of success.

Expanding Triangle Pattern Strategy

To further illustrate the Expanding Triangle Pattern, let’s consider an example, imagine a trader is analyzing the EUR/USD currency pair and notices an Expanding Triangle Pattern forming on the price chart. The horizontal resistance trendline is set at 1.2100, and the upward sloping support trendline is set at 1.1900.

As the pattern progresses, the price bounces off the support trendline and moves back up towards the resistance trendline. The trader notices that the volume of trades is increasing as the price approaches the resistance trendline, and the relative strength index (RSI) is also rising.

Based on these observations, the trader decides to enter a buy position at 1.2050, just below the resistance trendline. The trader sets a stop loss at 1.2000, just below the support trendline, and a take profit at 1.2150, above the resistance trendline.

As it turns out, the EUR/USD pair does break above the resistance trendline, and the trader’s buy position is successful. The price moves up to 1.2150, and the trader is able to close their position and realize a profit.

In this example, the Expanding Triangle Pattern helped the trader identify a potential breakout point in the market and provided a clear set of rules for entering and exiting a trade. By following these rules, the trader was able to place a trade with confidence and potentially increase their chances of success.

Buy Signal

  • If the price breaks above the resistance trendline, it can be seen as a sign of strength and a potential buy signal.
  • If the price bounces off the support trendline and moves back up towards the resistance trendline, it can be seen as a sign of bullish momentum and a potential buy signal.
  • If the volume of trades increases as the price approaches the resistance trendline, it can be seen as a sign of buying pressure and a potential buy signal.
  • If the relative strength index (RSI) is rising as the price approaches the resistance trendline, it can be seen as a sign of bullish momentum and a potential buy signal.

Sell Signal

  • A break below the support trendline may indicate weakness and be a sell signal.
  • If the price bounces off the resistance trendline and declines towards the support trendline, it may indicate bearish momentum and be a sell signal.
  • Increased trading volume as the price approaches the support trendline may indicate selling pressure and be a sell signal.
  • A falling relative strength index (RSI) as the price approaches the support trendline may indicate bearish momentum and be a sell signal.
