/**
* Represents a IgxDataChartComponent Slow Stochastic Oscillator indicator series.
* Default required members: High, Low, Close
*
* `SlowStochasticOscillatorIndicator` (SSO) displays the closing price relative to the high-low range over a given period of time. There are three types of Stochastic Oscillators: Fast, Slow, and Full. The Stochastic Oscillator is a momentum indicator that shows the relation of the current close price relative to the high/low range over a given time period using a scale of 0 to 100. It is based on the premise that prices will close near 100 in a rising market and closer to 0 in a declining market.
*
* The Fast Stochastic Oscillator Indicator is used to identify buying or selling divergences. The Slow Stochastic Oscillator uses a 3-day SMA and the Full Stochastic Oscillator is the Slow Stochastic Oscillator with time period.
*
* Using this indicator requires setting both the `HighMemberPath`, `LowMemberPath` and `VolumeMemberPath`.
