Lines 

Helps to draw trendlines in the chart(s). In order to perform this action you have to follow the steps:
1. Select the line type from the "Lines" menu.
2. Chose an extreme datapoint in the chart and place the mouse cursor to this first point you wish the line to be drawn from.
3. Press LEFT mouse button and move the mouse cursor to the second extreme datapoint of the chart (with mouse button held).
4. Release LEFT mouse button.
5. Click the RIGHT mouse button in the Chart Area to exit the "trendline" mode.

You can here select which type of Line you wish to draw from a given
datapoint (to be subsequently determined). The types of Lines which can be
drawn on a chart depend on the chart type. You can choose to draw a Line:
"Close"
A line drawn from the “Close” price of the first data point chosen through the
“Close” price of the second datapoint chosen.
"High/Low"
A Line drawn from either the “High” of the first datapoint through the “Low”
of the second datapoint, or from the “Low” of the first datapoint through
the “Low” of the second datapoint. At the first datapoint the High as well
as the Low is displayed, and it is the choice made between the High and the
Low on the first datapoint, which determines which of these the Line will go
through on subsequently chosen data points.
"FreeHand"
Where you can choose to draw a Line anywhere in the chart area to anywhere
else, regardless of the data points of the actual chart(s).
"Horizontal Close"
An automatic horizontal line is drawn through the Close value of the selected
bar.
"Horizontal High/Low"
An automatic horizontal line is drawn through the High or Low value of the
selected bar.
"Horizontal Freehand"
Where an automatic horizontal line is drawn from the datapoint chosen.
Fibonacci numbers, known under many names as the “golden ratio”, the “divine
proportion”, “Phi” (1.618) etc., was discovered by Leonardo Fibonacci.
In technical analysis the Fibonacci sequence translates into three
percentages: –38.2%, 50% and 61.8%.
The Fibonacci Fans function enables 3 diagonal trendlines to be drawn
automatically from any given datapoint. Chose an extreme datapoint (an
extreme Close or an extreme High or Low value) in the chart.
From the chosen data point, you draw a vertical line to another extreme in the
chart. This line will remain invisible, but the values of the Fibonacci Fans
will be calculated from the line drawn.
From the (invisible) line, 3 trendlines will be drawn (visible) representing
respectively 38.2%, 50% and 61.8% of the datapoints which make up the
invisible line. Fibonacci chartists use these 3 trendlines as indications for
where the market has areas of support and resistance.

Retracements
Also known as “Fibonacci Retracements” is a tool used by some traders,
particularly in the FX market, to calculate the scope of a retracement, i.e..:
temporary price reversals, which does not indicate a reversal in the market
trend as such. A “retracement” should therefore be distinguished from a
“reversal”.
A trendline is drawn from the top to the bottom of the latest “impulse wave”
(a strong move in price coinciding with the main direction of the markets
trend). When a trendline is thus drawn between extreme data points (either
extreme Close data or extreme High/Low data), three horizontal lines are
created: the first at 61.8% of the highest point in the trendline, the second
at 50%, the third at 38.2%. Many traders use these levels to monitor
support/resistance levels of the underlying trend.
After a significant price movement up or down, the new /resistance levels are often at or near the Fibonacci levels. Please note that once the Fibonacci lines are drawn, the initial trendline no longer is visible on the chart, enabling the user to focus on the three Fibonacci lines.
It is used for predicting resistance levels as well as key support. It is
created by first drawing a trend line between two extreme points, usually
high and low (from high to low). Fibonacci arcs are the three curves that
intersect the trend line at the retracement levels. The retracement levels
can be configured within "Fibonacci Arcs" window that is displayed after
drawing the trend line. The chosen values can be saved ("Save to General
Settings" button) so next time Fibonacci Arcs are drawn, the saved values
will be used as default. The arcs are estimations for support.
It is an indicator used to identify the periods when the price of an asset
will experience a significant amount of movement. Fibonacci Time Zones are a
series of vertical lines spaced at the Fibonacci intervals of 1, 2, 3, 5, 8,
13, 21, 34, etc. Each successive number is the sum of the two previous
numbers. The interpretation of Fibonacci Time Zones involves looking for
significant changes in price near the vertical lines.
