Vortex Indicator — what it is and how to use it in trading
Definition
The Vortex Indicator is a pair of trend-strength lines (+VI and -VI) comparing how far each bar's high and low move away from the previous bar's opposite extreme, oscillating around a shared reference near 1 rather than around zero.
How it works in the builder
The vortex_pos and vortex_neg operands take a period parameter (default 14). +VI measures upward movement — a +VI crossover above -VI reads as a bullish signal; -VI is the mirrored measure for downward movement.
What it looks like on the chart
Both lines are drawn crossing repeatedly around a shared mid reference, not zero — real Vortex genuinely oscillates around a value of 1. The selected line ("+VI" or "-VI") is highlighted bold and labelled, the other as a thin, muted dashed line.
Typical use
The classic signal is the crossover itself: vortex_pos crossed_above vortex_neg for a bullish trend shift, often paired with a trend-strength filter like ADX to avoid trading crossovers in a flat range.
Common pitfalls
+VI and -VI are built directly from bar-to-bar high/low movement rather than a smoothed trend estimate, so crossovers can happen fairly often even in a moderate range on noisy instruments — the indicator is usually paired with a separate trend-strength filter rather than traded on crossovers alone.
