trendlines

The Zig Zag Oscillator indicator provides a way of viewing the Zig Zag Indicator information in a different form, oscillating about 0. The indicator represents the percent change at each bar of the current price from the base price of the current Zig Zag leg. When the Zig Zag is currently in an uptrend state, the Zig Zag Oscillator will be above 0. Similarly, when the Zig Zag is in a downtrend state, the oscillator will be below 0. Optionally, reference lines may be drawn at any percent change level.

The automatic trend line indicator determines the current up trend and down trend line and draws them. Trend lines may also be drawn manually using the drawing tool on the charting toolbar, but this indicator does it automatically. The user specifies the number of periods to "look back" from the present to determine where to place the trend lines. The up trend line connect the lowest low in the user specified period with the next lowest low preceding the highest high for which the trend line is not penetrated.
