Ichimoku Cloud Values Issue

protected override void OnStart()
{
 ichi = Indicators.IchimokuKinkoHyo(9, 26, 52);
}

protected override void OnTick()
{
 IndicatorDataSeries senkouSpanA = ichi.SenkouSpanA;
 IndicatorDataSeries senkouSpanB = ichi.SenkouSpanB;
 ChartObjects.DrawHorizontalLine("ichiA", senkouSpanA.LastValue, Colors.Red);
 ChartObjects.DrawHorizontalLine("ichiB", senkouSpanB.LastValue, Colors.Blue);
}

I have made this simple cBot just to demonstrate the issue I am having. The result is shown below:

I was expecting the two lines to be lined up with the top and bottom of the cloud. Does anyone know if I'm doing something wrong or if this particular indicator works a bit differently?

Your assistance is appreciated.
