Technical Indicators - Fibonacci Time Extensions

Fibonacci Time Extensions are used to predict periods of price change (i.e. lows or highs). For example, after a downtrend, a reversal would be expected at a significant Fibonacci Time Extension line. Similarly, after an uptrend, a reversal warning could occur if a Fibonacci Time Extension was soon approaching.
The Fibonacci Time Extension tool is created by locating a significant high (low) and finding a significant retracement or extension low (high). The major Fibonacci ratios are then calculated and plotted by charting software.
