Trendlines can be drawn in the chart area to help identify a trend in price movements. There are three icons found in the top-right area above the chart to control the trendlines. Chose from Horizontal, Vertical or more sophisticated trendlines.

With a compass-like movement, three curved lines are drawn at 38.2%, 50% and 61.8%, from the desired point. These lines anticipate the support and resistance levels as well as possible ranges.

Fibonacci fans are diagonal lines which indicate areas of support and resistance. After the high and low of the chart is located, an invisible vertical line is drawn through the rightmost point. This invisible line is then divided into 38.2%, 50% and 61.8%, and lines are drawn from the origin through each of these points.

Fibonacci retracements are horizontal lines indicating areas of support or resistance. They are calculated by first locating the high and low of the chart, then drawing six lines: at 0% (the low on the chart), 23.6%, 38.2%, 50%, 61.8%, and 100% (the high on the chart). Fibonacci extensions are also drawn at 161.8%, 261.8%, 423.6%.

After a significant price movement up or down, the new support and resistance levels may settle at or near these lines.

Note: Fibonacci retracements work best in trending markets with clearly defined swings where (in an uptrend) the highs get consistently higher along with the retrenchment lows (and vice versa for a downtrend).

Fibonacci time zones are a series of vertical lines spaced in increments that conform to the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, etc.). These lines indicate areas in which major price movement may be expected.

Pivot points are calculated from previous-period prices, and are used to determine resistance and support levels that may signal an entry/exit point.

marketindex plots five pivot trendlines: the pivot, two resistance and two support levels. These lines are calculated from the previous time frame (for example, for the previous 5 seconds on the 5-second chart, or for the previous day on the 1-day chart).

To view a pivot point overlay, select Pivot Points from the Add Study menu, then click the + sign. For details, see Overlays.

Speed resistance lines are used in marketindex to create a fan similar to the Fibonacci fan. However, rather than using Fibonacci numbers, the fan uses calculations by thirds. Many investors watch for a move below the two-thirds level as a signal of continued retracement toward the one-third level.

Click the minimum and maximum points of an identifiable trend to create the reference line. Two other lines are drawn fanning out from this line at angles of 33.33% and 66.66%. These lines represent the possible price support on retracement. They may give insight to both the degree and rate of retracement (hence the term "speed lines").
