It is developed by Thomas DeMark. It is an Oscillator indicator.
It can be used in long term and short term time frames.
This Oscillator fluates between 100 land -100 levels.
If it runs over 60 level means, it shows overbought position.
If it runs down to -60 level means, it shows oversold position.
Better to use it with EMA 50.
