Vortex
Identifies positive and negative directional movement via VI+ and VI-. The Vortex Indicator (VI) plots two lines: VI+ (upward movement) and VI- (downward movement) based on true ranges. VI+ > VI- — an uptrend, VI- > VI+ — a downtrend. The crossover of the lines is used as a trend-change signal.
Formula:
+VM = |High - Low_prev|-VM = |Low - High_prev|+TR = SUM(TR, n)VI+ = SUM(+VM, n) / +TRVI- = SUM(-VM, n) / -TRTriggers
Section titled “Triggers”| Trigger | Direction | Condition | Description |
|---|---|---|---|
| Signal line cross up | 🟢 Buy | The main line crossed the signal line from below to above — a buy signal. | VI+ crosses VI− from below to above — a bullish signal: upward directional movement begins. |
| Signal line cross down | 🔴 Sell | The main line crossed the signal line from above to below — a sell signal. | VI+ crosses VI− from above to below — a bearish signal: downward directional movement begins. |
| Slope turns positive | 🟢 Buy | The indicator’s slope turned positive — an upward reversal. | The VI+ line changes its slope from descending to ascending — the indicator stopped falling and started rising. |
| Slope turns negative | 🔴 Sell | The indicator’s slope turned negative — a downward reversal. | The VI+ line changes its slope from ascending to descending — the indicator stopped rising and started falling. |
| Line diverges from signal | ↕️ Both | The distance between the main line and the signal line increased by the specified amount. | VI+ and VI− diverge — directional movement is strengthening. |
| Line converges to signal | ↕️ Both | The distance between the main line and the signal line decreased by the specified amount. | VI+ and VI− converge — directional movement is weakening, a trend change is possible. |
| Enter uptrend | 🟢 Buy | The indicator entered an uptrend. | Fires when a trend indicator (ADX/DMI, Ichimoku, Supertrend, etc.) signals the start of an uptrend. |
| Enter downtrend | 🔴 Sell | The indicator entered a downtrend. | Fires when a trend indicator (ADX/DMI, Ichimoku, Supertrend, etc.) signals the start of a downtrend. The specific condition depends on the indicator. |
