// The indicator evaluates the "efficiency" of price movement relative to the volume expended.
// It helps identify hidden unloading opportunities for major players and trend exhaustion points.
//
// Logic: Measures the ratio of the squared true range (ATR)
//
// Signals:
// KSI spikes upward: Price is soaring on low volume (market emptiness, reversal is imminent).
// KSI drops to zero: Huge volume is not moving the price (order density, trapped flat).
