About

Vortex Oscillator plots +VI and -VI — sums of upward vs downward range moves normalised by true range. When +VI crosses -VI up, the trend is bullish; the opposite for bearish.

Crossover of the two VIs is the entry signal.
Raise Length for steadier trend calls.
Pair with an ADX filter to confirm trend strength.
