The original Vortex Indicator consists of two lines:
- VI+ (Positive Vortex Movement): Tracks upward price movement.
- VI- (Negative Vortex Movement): Tracks downward price movement.
In the version it will show as an Histogram moving above and under a zero line.
- Uptrend: When the Vortex crosses above the zero line, it suggests that an upward trend might be starting or continuing.
- Downtrend: When the Vortex line crosses below the zero line, it indicates the possibility of a downward trend.
