Speed Resistance Lines ("SRL"), sometimes called
1/3-2/3 lines, are a series of trendlines that divide a price move into
three equal sections. They are similar in construction and
interpretation to Fibonacci Fan Lines.
Interpretation
Speed Resistance Lines display three trendlines. The
slope of each line defines a different rate at which pricing
expectations are changing.
Prices should find support above the 2/3 line. When
prices do fall below the 2/3 line, they should quickly drop to the 1/3
line where they should then again find support.
Example
The following charts show McDonald's price and Speed
Resistance Lines.
The initial trendline was drawn from the low point
labeled "A" to the high point labeled "B." You can see that prices found
support each time they fell to the 2/3 line. When prices finally
penetrated the 2/3 line (at point "C") they quickly fell to the 1/3 line
where they again found support.
Calculation
To draw Speed Resistance Lines:
Draw a line from a major low to a major high.
Draw a vertical line on the day the major high
occurred. Divide this vertical line into thirds.
Draw lines from the major low so they intersect
the vertical line at the 1/3 and 2/3 levels.
