I'd like to be able to specify a condition where the weekly close is higher than X percent of the previous 52 week closes.

For instance, I'd like to identify if the weekly close is higher than 65% of the previous 52 closes.

Is that possible?

Please try using the following RealCode Condition with a Weekly Bar Interval:

'|*****************************************************************|
'|*** StockFinder RealCode Condition - Version 5.0 www.worden.com 
'|*** Copy and paste this header and code into StockFinder *********
'|*** Condition:Close Above
'|******************************************************************
'# Period = UserInput.Integer = 52
'# Percent = UserInput.Single = 65
Dim Count As Integer = 0
Dim Threshold As Single = Period * Percent / 100
If CurrentIndex >= Period Then
	For i As Integer = 1 To Period
		If Price.Last > Price.Last(i) Then
			Count += 1
			If Count >= Threshold Then
				Pass
				Exit For
			End If
		End If
	Next
Else
	SetIndexInvalid
End If

As always Bruce, thanks.  That is perfect.

You're welcome.
