Fibonacci Time Extension Lines Drawing Object

Fibonacci Time Extension Lines are analytical drawing tools used to monitor support and resistance levels as well as breakout price activity. Support indicates a low or series of troughs where price activity has not penetrated. Resistance indicates a high or series of peaks where price activity has not penetrated. Identifying and monitoring these two levels can assist in determining whether a market will stay on course or reverse its course. Penetration through a support line or resistance line may indicate a market reversal. Support and resistance lines can also be used in conjunction with Percent Retracement analysis to identify past trend correction patterns. These patterns can then assist in predicting future patterns.


You can also use the shortcut menu for a selected object component (identified with small squares) to change the drawing properties such as Color, Style, Weight, and any object specific settings.

Formatting a Fibonacci Time Extension Lines Settings

The format settings for Price and Time Extension lines are similar except that Price Extension Lines are horizontal while Time Extension Lines are vertical.  Both types of lines are based on price or time extensions of an underlying trend line and relative levels of support/resistance for Price Lines and time/date for Time Lines. The Settings tab is used to modify settings for the extension lines by specifying their percentage as well as other properties.
