$x = 3

$CloseCheck1 = _Excel_RangeRead($oWorkbook, Default, "C"&$x+1)
$CloseCheck2 = _Excel_RangeRead($oWorkbook, Default, "C"&$x+2)
$CloseCheck3 = _Excel_RangeRead($oWorkbook, Default, "C"&$x+3)
$CloseCheck4 = _Excel_RangeRead($oWorkbook, Default, "C"&$x+4)
$CloseCheck5 = _Excel_RangeRead($oWorkbook, Default, "C"&$x+5)
$CloseCheck6 = _Excel_RangeRead($oWorkbook, Default, "C"&$x+6)
$CloseCheck7 = _Excel_RangeRead($oWorkbook, Default, "C"&$x+7)
$CloseCheck8 = _Excel_RangeRead($oWorkbook, Default, "C"&$x+8)
$CloseCheck9 = _Excel_RangeRead($oWorkbook, Default, "C"&$x+9)
$CloseCheck10 = _Excel_RangeRead($oWorkbook, Default, "C"&$x+10)

Local $aArray = StringSplit($CloseCheck1&","&$CloseCheck2&","&$CloseCheck3&","&$CloseCheck4&","&$CloseCheck5&","&$CloseCheck6&","&$CloseCheck7&","&$CloseCheck8&","&$CloseCheck9&","&$CloseCheck10,",")
$DMAX = _ArrayMax($aArray, 1, 1)
$DMIN = _ArrayMin($aArray, 1, 1)

$n = 11
While 1
$CloseCheckn = _Excel_RangeRead($oWorkbook, Default, "C"&$x+n)

If $CloseCheckn > $DMAX Then
Global $DMAX = $CloseCheckn
EndIf

If $CloseCheckn < $DMIN Then
Global $MIN = $CloseCheckn
EndIf

If $CloseCheckn = "" Then
   ExitLoop
EndIf

$n = $n + 1
WEnd

_Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $DMAX, "P1")
_Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $DMIN, "P2")

 

 

Thanks

Take the data in an array using 

_Excel_RangeRead

and use 

_ArrayMax

to find the highest value.

Thank Anoop, I try, but it dont work. This is my code : 

Global $oAppl = _Excel_Open()
Global $sWorkbook1 = @ScriptDir & "\Test.xls"
Global $oWorkbook1 = _Excel_BookOpen($oAppl, $sWorkbook1, Default, Default, True)

$aResult = _Excel_RangeRead($oWorkbook1, 2, "F1:F39", 1)
$max = _ArrayMax($aResult, 0, 1)
MsgBox($MB_SYSTEMMODAL, "","$max  is : " & $max)

#include <Excel.au3>
#include <Array.au3>

Global $oAppl = _Excel_Open()
Global $sWorkbook1 = @ScriptDir & "\Test.xls"
Global $oWorkbook1 = _Excel_BookOpen($oAppl, $sWorkbook1, Default, Default, True)

$aResult = _Excel_RangeRead($oWorkbook1)
_ArrayDisplay ($aResult)
$max = _ArrayMax($aResult, 1)
MsgBox($MB_SYSTEMMODAL, "","$max  is : " & $max)

Please try with this. Check if array displayed correctly.

Sorry,... my mistake .   

The code is worked. 

This is my errors :3 

"$aResult = _Excel_RangeRead($oWorkbook1, $oWorkbook1.Activesheet, "F1:F39", 1)|"
 

 

 

Global $oAppl = _Excel_Open()
Global $sWorkbook1 = @ScriptDir & "\Test.xls"
Global $oWorkbook1 = _Excel_BookOpen($oAppl, $sWorkbook1, Default, Default, True)

$aResult = _Excel_RangeRead($oWorkbook1, $oWorkbook1.Activesheet, "F1:F39", 1)
$max = _ArrayMax($aResult, 0, 1)
MsgBox($MB_SYSTEMMODAL, "","$max  is : " & $max)

 

So... Thank so much Anoop

Or you could let Excel calculate the max value:

Global $oAppl = _Excel_Open()
Global $sWorkbook1 = @ScriptDir & "\Test.xls"
Global $oWorkbook1 = _Excel_BookOpen($oAppl, $sWorkbook1, Default, Default, True)
_Excel_RangeWrite($oWorkbook1, $oWorkbook1.Activesheet, "=MAX(F:F)", "A1", False) ; Modify the target "A1" range if needed
$iMax = _Excel_RangeRead($oWorkbook1, $oWorkbook1.Activesheet, "A1", 1) ; Modify the source "A1" range if needed
MsgBox($MB_SYSTEMMODAL, "","$iMax  is : " & $iMax)
_Excel_BookClose($oWorkbook1, False) ; Close book without saving
