Trend Line

TradingKeyTradingKeyTue, Apr 15

A trend line is a graphical representation on a chart that consists of a sequence of highs or lows forming a straight line. It is created by connecting two or more price points with a straight line.

The main purpose of a trend line is to highlight the historical trend of price movements and to indicate levels of support and resistance. In technical analysis, trend lines are fundamental components of various chart patterns, including trend channels, wedges, flags, and triangles.

Trend lines serve several functions:

  • To identify and confirm trends
  • To forecast levels of support and resistance

Trend lines can be drawn from highs (indicating resistance) or lows (indicating support). To create a trend line, simply connect either the high prices or low prices on a price chart. The resulting line represents the trend line.

Typically, the trend line is extended into the future to identify sloped areas of support and resistance. They visually represent support and resistance levels. While only two points are needed to draw a trend line, using more points strengthens the trend line's validity.

There are two main types of trend lines: ascending and descending.

Ascending Trend Line

An ascending trend line, or uptrend line, is created by connecting the lows, where the most recent low price is higher than the previous low price. This line extends into the future and can be viewed as a level of support. Lines with a positive slope that support price action indicate increasing demand (more buyers than sellers). As long as the price remains above this line, a bullish trend is in place.

Descending Trend Line

A descending trend line, or downtrend line, is the opposite of an ascending trend line. It is formed by connecting the highs, where the most recent high is lower than the previous high. This line also extends into the future and serves as a level of resistance. Lines with a negative slope that resist price action indicate increasing supply (more sellers than buyers). As long as the price stays below this line, a bearish trend is present.

The common trading strategy regarding trend lines is that if the price bounces upward from a trend line's support or downward from a trend line's resistance, it indicates the trend's strength. Prices often retest a sloped trend line multiple times before breaking it.

When a trend line is broken, especially with high trading volume, the momentum can push the price significantly above or below the broken trend line, signaling a potential trend reversal.

Traders may have varying opinions on how far apart the connected price points should be and whether the trend line should connect to a candlestick's wick or body. Regardless of the method used to construct trend lines, it is important to remember that all trend lines will eventually break.

Tariff

A tariff is a tax levied by a government on goods and services brought in from other nations. Tariffs have several functions, such as generating government revenue, shielding domestic industries from foreign competition, and shaping trade policies. In addition to being a revenue source for the government, tariffs can regulate foreign trade and impose taxes on foreign products to promote or protect domestic industries. Tariffs are among the most commonly used tools of protectionism, alongside import quotas, export quotas, and other non-tariff trade barriers. The term "tariff" comes from the French word tarif, meaning 'set price', which is derived from the Italian tariffa, meaning 'mandated price; schedule of taxes and customs'. Ultimately, this term traces back to the Arabic word taʿrīf, meaning 'notification'.
