What Is A Bull Flag Pattern?

A bull flag, also known as a "bullish flag", is a technical analysis bullish continuation chart pattern that signals a continuation in the price of an existing uptrend. A bull flag leads to a further increase in the price of a market.

A bull flag forms when there is a steep increase in the price of a market, followed by a period of rangebound and consolidation price action.

A bull flag resembles the shape of a "flag".

Bull Flag Components

bull flag components

In order to identify a bull flag chart pattern, there needs to be certain components displayed on the price chart of a market.

The components of a bull flag are:

  • A rising flagpole: This is an uptrend line that illustrates the strong bullish direction of the price of the market. It is called the "flagpole" of the bull flag.
  • A declining support level: This is a short downtrending support level that connects the swing lows together. It is usually where a trader will place a stop-loss when trading the bull flag pattern.
  • A parallel declining resistance level: This is a short downtrend resistance level of the bull flag. It connects the swing highs together and it is usually the area where traders buy the breakout of a bull flag pattern.
