I am trying to find stocks that gap up or down by at least a point.
If they gap down then note the low of that day & if they gap up note the High of that day. Then I want to know the next day that low or high that we noted is traded again.
Let me give you an example (I hope this helps):
Stock DKS
On 5/22/08 it had a large gap down; with a low of 21.03
the stock continued to trade but did not touch that low till 6/19/08
I want to run my scan in blocks everyday but on 6/19 I would have wanted to see DKS lite up.
Thanks

I'm not sure if the following RealCode Condition is what you want, but it does trigger for DKS on 6/19/08:
'#Cumulative
Static GapHigh As Single
Static GapLow As Single
If isFirstBar Then
GapHigh = Single.NaN
GapLow = Single.NaN
End If
If Price.High >= GapHigh Or Price.Low <= GapLow Then
Pass
If Price.High >= GapHigh Then GapHigh = Single.NaN
If Price.Low <= GapLow Then GapLow = Single.NaN
End If
If Price.Low >= Price.High(1)+1 Then GapHigh = Price.High
If Price.High <= Price.Low(1)-1 Then GapLow = Price.Low

Thanks!
Now if want to know the next time it actually closes above/below the noted gap price what changes would i need to make to the code?

Could you please clarify your most recent request? It is not detailed enough for me to determine what you want.

Bruce,
you have it set to light up when it trades the low of the gap again, how can i change it to light up when it closes below the low of the gap?
Thanks

I already have it setup so it lights up when the stock trades at or below the Low of the Gap Low Day or at or above the High of the Gap Up Day. If you don't want to include the possibility of equalities, change:
If Price.High >= GapHigh Or Price.Low <= GapLow Then
Pass
If Price.High >= GapHigh Then GapHigh = Single.NaN
If Price.Low <= GapLow Then GapLow = Single.NaN
To:
If Price.High > GapHigh Or Price.Low < GapLow Then
Pass
If Price.High > GapHigh Then GapHigh = Single.NaN
If Price.Low < GapLow Then GapLow = Single.NaN

I know you setup so it lights up when the stock trades at or below the Low of the Gap Low Day or at or above the High of the Gap Up Day
what I want is : light up when the stock closes at or below the Low of the Gap Low Day or at or above the High of the Gap Up Day
thanks

Try changing:
If Price.High >= GapHigh Or Price.Low <= GapLow Then
Pass
If Price.High >= GapHigh Then GapHigh = Single.NaN
If Price.Low <= GapLow Then GapLow = Single.NaN
To:
If Price.Last >= GapHigh Or Price.Last <= GapLow Then
Pass
If Price.Last >= GapHigh Then GapHigh = Single.NaN
If Price.Last <= GapLow Then GapLow = Single.NaN

Thanks thats perfect.
One last thing, can I have a count that I can sort by how many days between Gap and the breaking of the gap?

Do you want it to be a running count that returns the number of days since the Gap while it is happening (and then drops back to zero or, probably better, a count that can't happen like negative one), do you want it to always return the number of days for the last Gap and fill or do you want it to return something else entirely.

I am looking for the number of bars between the GapHigh or GapLow and the day it passes it again which is the day that lights up. so in the DKS example above it would be 6/19/08 minus 5/22/08.
Thank you

Below is a screen image of CMG. It is an interesting case as the gap lated 194 days before another gap occurred on 2/15/207. The condition indicator is a little different that your request. It is true from the first day until the day the price traget is crossed. You can modifiy it for the close. The gap is a userinput and is set to 1.0
The indicator plots the day count and is -1 if no current gap. Following the screen image is the code for the indicator. Note the plot line can be replaced with the commented pass code at the botton to create the condition code.
'# gapSize = userinput.single = 1.00
static LowerLow as single
static HigherHi as single
static daysSinceGap as single
static targetPriceTraded as boolean
Static wasUpGap As Boolean
Dim willPass As Boolean
If isFirstBar Then
daysSinceGap = -1
LowerLow = 0
HigherHi = 10000
targetPriceTraded = False
wasUpGap = false
end if
'
' check for existing gap
'
if daysSinceGap >= 0 then
'
' unresolved gap price target
'
daysSinceGap += 1
If wasupGap Then
'
' was gap up, check for price traded
'
If price.high > higherHi And _
price.Low < higherHi Then
targetPriceTraded = True
daysSinceGap = -1
higherHi = 10000
End If
Else
'
' was gap down, check for price traded
'
If price.low < lowerLow And _
price.High > lowerLow Then
targetPriceTraded = True
daysSinceGap = -1
lowerlow = 0
End If
End If
End If
'
' Note the target price could be traded
' and a new gap could be produced so check for gap
'
'----------
'
' set willPass as targetPricedTraded may get reset
' during gap check
'
willPass = targetPriceTraded
If price.low > price.high(1) + gapsize Then
'
' new gap up
'
wasUpGap = true
HigherHi = price.high
targetPriceTraded = false
daysSinceGap = 0
ElseIf price.high < price.low(1) - gapsize Then
'
' new gap down
'
wasUpGap = false
lowerLow = price.low
targetPriceTraded = false
daysSinceGap = 0
End If
'========================
' plot code
'========================
plot = daysSinceGap
'========================
' condition code, commented
'
' to create a condition indicator
' copy the code and paste into a condition edit window
' and remove the comment quote and the plot line above
'========================
'If willPass = True Then
' targetPriceTraded = False
' pass
'ElseIf daysSinceGap > -1 Then
' pass
'End If
'
