//------------------------------------------------------------------------------
//
//  This looks at four different cyclic indicators together at one time. When
//  three oscillators synchronize, this signals a strong buy or sell.
//
//  The white dotted line is the Volume Flow Indicator, or VFI. If the VFI is
//  above the zero line, look for synchronized oscillators rising out of an
//  oversold condition -- this is a good buy signal. If VFI is below zero, look
//  for overbought conditions and short, instead.
//
//  The REI is Tom DeMark's Range Expansion Index. This is the most leading
//  indicator included here. The DSS is a double-smoothed stochastic, good for
//  timing and exact buy or sell point. And the IFT is the Inverse Fisher
//  Transform function.
//
//  This indicator works well for any time frame. All it takes is a little
//  getting used to before you become intuitive with it.
//
//  I named it the MultiCycle for lack of a better name.
