  2. Flag: There is a rectangular or channel-shaped consolidation area in which the price moves in a narrow range known as the flag. This phase signifies a temporary pause in the market's bullish activity
  3. Declining Support Level: This is a downtrending support level that connects the swing lows together. This line is where a trader places a stop-loss when trading the bull flag pattern
  4. Declining Resistance Level: This is a downtrend resistance level of the bull flag that connects the swing highs together. A price break above this level is where a trader places a buy order. This is a parallel trendline to the support trendline

Bull flag components

What Is The Formation Process Of a Bull Flag Pattern?

The bull flag pattern formation process involves firstly financial market prices rising in a bull trend with the formation of higher swing high prices and higher swing low prices on a price chart. This is the flagpole component and the first part of the formation process of bull flag chart patterns.

The second part of the bull flag pattern formation process involves a price pause after a bull trend with the market consolidating and moving within a sideways price range with two or more swing high prices forming and two or more swing low prices forming. This price range sees the flag component formation.

The third part of the bull flag formation process involves price surging out of the consolidation range and moving higher in a rising trend. This sees the completion of the bull flag formation.

What Happens After a Bull Flag Pattern Forms?

After a bull flag pattern forms, the asset price rises above the pattern resistance point and continues higher in a bullish breakout direction making higher swing lows and higher swing highs.

How To Identify a Bull Flag Pattern

To identify a bull flag pattern, traders begin be observing a prevailing bullish uptrend in the market price action. This price surge is the identification of the flagpole. The next part of the bull flag pattern identification is the appearance of the consolidation phase where asset prices move within parallel downtrending trendlines where the support and resistance levels of the pattern are identified. During this price consolidation period, traders look for lower trading volume.

Thirdly, draw a lower boundary parallel downward sloping trend line from left to right that connects the swing low points together. This marks the pattern's support area component and the bull flag drawing completion.
