The Vortex Indicator (VI) is composed of 2 lines that show both positive (VI +) and negative (VI -) trend movement. It was inspired by certain motions found in water and was developed by Etienne Botes and Douglas Siepman. The Vortex Indicator has a relatively straight forward application: it is used by traders to identify the start of a trend. The VI + line crossing the VI - line (or a key level) could be seen as a bullish signal. The VI - line crossing the VI + line (or a key level) could be seen as a bearish signal. These are key trend change points. The indicator is often used in combination with other signals.
A problem I noticed with the built in Vortex indicator was that it didn't include any defined thresholds that are important to understanding how to read the vortex indicator. So I modified the vortex indicator in order to have the thresholds built in so you don't have to draw horizontal lines on your chart.
Scripted longs and shorts to the vortex indicator. It doesn't work like Vortex due to the two plots never crossing to congest.
Blue line: longs
Red line: shorts
Histogram: net volume, ohlc4 of both. Green if previous candle close had lower net volume, black if the previous candle close had more.
Deviance from the histogram: increased volume for the long or short ...
