The main oscillator (orange/blue) histogram is the RCV-MACRS (Relative Candle Volatility driven MACD modulated RSI) -- basically a sensitive indicator of volatility trends.
The yellow/lavender colored oscillator is a proprietary asymmetric differential oscillator (ADO) which is modulated by the main oscillator. When this (thinner line) secondary oscillator is > 0, it is yellow; and when it is < 0, it is lavender. The user can select the order of the differential (i.e. Order 1 = Momentum, Order 2 = Acceleration, Order 3 = Jerk, Order 4 = Snap, Order 5 = Crackle, Order 6 = Pop). This oscillator provides details of the more subtle underlying/hidden trends that is emerging or brewing, and may hint of an incoming move ahead of time. Divergence in the sign and slope of this secondary oscillator with respect to the main oscillator may provide a useful edge for trade setup.
A (thick transparent maroon) volume-momentum oscillator is also provided (which can be switch to the volume oscillator in the settings).
A cluster of circle markers may indicate a significant price swing incoming. The red background-highlights indicate periods of low volume and volatility.
