บทที่ 8 Fibonacci extension
Fibonacci extension levels are not used as much as retracements, but they are still worth examining. As opposed to Fibonacci retracement levels, which are spread between the swing low and swing high, Fibonacci extension levels reach past the swing high or swing low.
They are used to identify potential resistance levels exceeding the swing high or to identify support levels below the swing low. They are, however, much more speculative than the Fibonacci retracement levels. The most commonly used Fibonacci extension levels are 1.236, 1.382, 1.5, 1.618 and 2.618.
Fibonacci levels are a fairly useful trading tool with various usages. They can be used to identify support and resistance levels and also potential targets past new highs or lows. As is the case with other indicators, the use of Fibonacci retracement is highly subjective.
That being said, many traders use Fibonacci retracement in combination with other indicators and technical signals, demonstrating its effectiveness when used correctly.
