I need help to write a Realcode rule to find a two day low reversal. Criteria 1) price just did a two day low on the daily chart. 2) On the hourly chart in realtime, price moving up making a new high, taking out the last completed hourly-high candle.

I'm not sure I'm correctly interpreting your intended meanings for "just did a two day low on the daily chart" and "taking out the last completed hourly-high candle", but you may want to try the following RealCode Rule on a 1-Hour Chart. We can help you modify it with additional clarification from you if it does not meet your needs.
Static DayLow(1) As Single
Static TwoDayLow As Boolean
Static DayCount As Integer
If isFirstBar Then
DayLow(1) = Single.NaN
DayLow(0) = Single.NaN
TwoDayLow = False
DayCount = 0
Else If Price.DateValue.DayOfYear <> Price.DateValue(1).DayOfYear Then
DayLow(1) = System.Math.Min(Price.Low, DayLow(0))
DayLow(0) = Price.Low
DayCount += 1
End If
DayLow(1) = System.Math.Min(Price.Low, DayLow(1))
DayLow(0) = System.Math.Min(Price.Low, DayLow(0))
If DayCount >= 2 Then
If TwoDayLow = True AndAlso _
Price.High > Price.High(1) Then
Pass
End If
Else
SetIndexInvalid
End If
If DayLow(1) = Price.Low Then
TwoDayLow = True
Else
TwoDayLow = False
End If

Bruce, I want todays candle to have made a new low, then the hourly candle to make a new high in real-time. If you look at the symbol KG, it made a new two day low today. On the hourly chart I want the Realcode to trigger when price moved up making a new 2 bar (hourly) high in realtime. On the symbol KG it would have triggered at 11.43.

So you need the Rule to be for a 1-Minute Chart instead of a 1-Hour Chart? A RealCode Rule that just returns True whenever it is a 2-Day Low and a 2-Hour High would return True for KG before 11:43 AM ET on December 9, 2009 (and wouldn't actually be True at that point in the day).
Static DayLow(1) As Single
Static HourHigh(1) As Single
Static TwoDayLow As Boolean
Static TwoHourHigh As Boolean
Static DayCount As Integer
If isFirstBar Then
DayLow(1) = Single.NaN
DayLow(0) = Single.NaN
HourHigh(1) = Single.NaN
HourHigh(0) = Single.NaN
TwoDayLow = False
TwoHourHigh = False
DayCount = 0
Else If Price.DateValue.DayOfYear <> Price.DateValue(1).DayOfYear Then
DayLow(1) = DayLow(0)
DayLow(0) = Price.Low
HourHigh(1) = System.Math.Max(Price.High, HourHigh(0))
HourHigh(0) = Price.High
TwoDayLow = False
TwoHourHigh = False
DayCount += 1
Else If Price.DateValue.Hour <> Price.DateValue(1).Hour Then
HourHigh(1) = HourHigh(0)
HourHigh(0) = Price.High
TwoHourHigh = False
End If
DayLow(0) = System.Math.Min(Price.Low, DayLow(0))
If Price.Low < DayLow(1) Then
DayLow(1) = Price.Low
TwoDayLow = True
End If
HourHigh(0) = System.Math.Max(Price.High, HourHigh(0))
If Price.High > HourHigh(1) Then
HourHigh(1) = Price.High
TwoHourHigh = True
End If
If DayCount >= 2 Then
If TwoDayLow = True AndAlso _
TwoHourHigh = True Then
Pass
End If
Else
SetIndexInvalid
End If

Bruce,Firstly, thanks for your help. The first Realcode rule is almost perfect. The only change I would ask you to make is for todays low to be lower (a must) than yesterdays low. I'm using this on the 1- hour chart.

Please see if this works better for you:
Static DayLow(1) As Single
Static TwoDayLow As Boolean
Static DayCount As Integer
If isFirstBar Then
DayLow(1) = Single.NaN
DayLow(0) = Single.NaN
TwoDayLow = False
DayCount = 0
Else If Price.DateValue.DayOfYear <> Price.DateValue(1).DayOfYear Then
DayLow(1) = DayLow(0)
DayLow(0) = Price.Low
TwoDayLow = False
DayCount += 1
End If
If DayCount >= 2 Then
If TwoDayLow = True AndAlso _
Price.High > Price.High(1) Then
Pass
End If
Else
SetIndexInvalid
End If
DayLow(0) = System.Math.Min(Price.Low, DayLow(0))
If Price.Low < DayLow(1) Then
DayLow(1) = Price.Low
TwoDayLow = True
Else
TwoDayLow = False
End If

Bruce, that last Realcode works perfect, thanks.Would it be possible to modify that last Realcode to trigger when price has crossed up through the hourly 8exp moving average. Example 1The stock ICA, made a new low (lower than the day before daily candle), then when price crossed up through the 8exp on the 1-hour chart to trigger. ICA should have triggered on the second last hour of the day. Example 2On SFL it made a new lower low (lower than the day before daily candle), it wasn't till the last hour when it would have triggered as it crossed up through the 8 exp on the 1 - hour chart.

If you Drag and Drop the Moving Average into the Code tab of the RealCode Editor, it should create something similar to the first line of the following RealCode Rule:
'# MA = indicator.MovingAverage
Static DayLow(1) As Single
Static TwoDayLow As Boolean
Static DayCount As Integer
If isFirstBar Then
DayLow(1) = Single.NaN
DayLow(0) = Single.NaN
TwoDayLow = False
DayCount = 0
Else If Price.DateValue.DayOfYear <> Price.DateValue(1).DayOfYear Then
DayLow(1) = DayLow(0)
DayLow(0) = Price.Low
TwoDayLow = False
DayCount += 1
End If
If DayCount >= 2 Then
If TwoDayLow = True AndAlso _
Price.Last > MA.Value AndAlso _
Price.Last(1) <= MA.Value(1) Then
Pass
End If
Else
SetIndexInvalid
End If
DayLow(0) = System.Math.Min(Price.Low, DayLow(0))
If Price.Low < DayLow(1) Then
DayLow(1) = Price.Low
TwoDayLow = True
End If
