if (work[index, 1] != 0)
VZO[index] = 100.0 * work[index, 0] / work[index, 1];

// Calculate VZOC color (Volume Zone Oscillator Color Index)
VZOC[index] = (VZO[index] > 0) ? 1 : (VZO[index] < 0) ? 2 : 0;

// Calculate LevUp and LevDn (to draw filling)
LevUp[index] = Math.Max(VZO[index], 0);
LevDn[index] = Math.Min(VZO[index], 0);
}
