 Posted: Mon Apr 23, 2012 11:09 am Post subject: Let me know how to use the TimeCurrent() function |
 |
|
Hi,
I have to create a indicator by C++ Language.
I have been troubled for execution error occurs when using the TimeCurrent() function.
I was testing with the following sample code.
Result of checking the logs from Print() function, I'm sure that Time() function is executed without any problems.
And Pop-up message is displayed when executed the TimeCurrent() function.
Please check the following sample code and Screen Shot.
Let me know how to use the TimeCurrent() function.
Do I need to obtain the latest version of the "IndicatorInterfaceUnit.h"?
| Code: | EXPORT void __stdcall Calculate(int pIndex) {
char WorkText[100];
if (pIndex == 0) {
sprintf(WorkText, "Time(pIndex)=%f", Time(pIndex));
Print(WorkText);
sprintf(WorkText, "TimeCurrent()=%f", TimeCurrent());
Print(WorkText);
}
} |

Please help me who have programming skills.
Could you show me your sample code.
I think I should move to "Programming lessons Forum" this question.
But, I couldn't find operation for "Forum change".

Hi,
not sure about C++
I use TimeToStr function in Delphi to show time variable value:
| Code: | | Print ('Current Time: '+TimeToStr (TimeCurrent())); |

Hi, Stonev.
Thank you for your reply.
I was able to understand that you can use the TimeCurrent() function in Delphi.
I believe TimeCurrent() function is also available in C++.
I think there is some problem in my environment(Include files).
However, I can create the indicator that don't use the TimeCurrent() function.
Anyone,
Please show me your "Include Files" and "C++ Sample Code".
Atsushi

I don't see any crash problem both release n debug builds in MS VC 2010 express.
Only issue i had is i dont see any Print() out.
Sample Code.
| Code: |
//---------------------------------------------------------------------------
// Forex Tester 2 Inside Bar C++ Example Provided by Wessel
//---------------------------------------------------------------------------
#include <windows.h>
#include "IndicatorInterfaceUnit.h"
#include "TechnicalFunctions.h"
#define EMPTY_VALUE 0
// External variables
int insideBarSymbol = 225,
insideBarX = 0,
insideBarY = -10;
// Buffers
TIndexBuffer insideBarIndex;
//---------------------------------------------------------------------------
// Initialize indicator
//---------------------------------------------------------------------------
EXPORT void __stdcall Init()
{
// define properties
IndicatorShortName("Inside Bar");
SetOutputWindow(ow_ChartWindow);
SetEmptyValue(EMPTY_VALUE);
// register options
AddSeparator("Inside Bar, Coded by WesseldR v1.0 Feb2011");
AddSeparator("Inside Bar Parameters");
RegOption("Inside Bar Symbol", ot_Integer, &insideBarSymbol);
SetOptionRange("Inside Bar Symbol", 1, 256);
RegOption("Inside Bar X-offset", ot_Integer, &insideBarX);
SetOptionRange("Inside Bar X-offset", -MaxInt, MaxInt);
RegOption("Inside Bar Y-offset", ot_Integer, &insideBarY);
SetOptionRange("Inside Bar Y-offset", -MaxInt, MaxInt);
// create buffers
insideBarIndex = CreateIndexBuffer();
IndicatorBuffers(1);
SetIndexBuffer(0, insideBarIndex);
SetIndexStyle(0, ds_Symbol, psSolid, 1, clYellow);
SetIndexSymbol(0, insideBarSymbol,insideBarX,insideBarY);
SetIndexLabel(0, "Inside Bar");
}
EXPORT void __stdcall OnParamsChange()
{
SetIndexSymbol(0,insideBarSymbol,insideBarX,insideBarY);
}
//---------------------------------------------------------------------------
// Calculate requested bar
//---------------------------------------------------------------------------
EXPORT void __stdcall Calculate(int index)
{
char WorkText[100];
//if(index == 0) // We only pick completed bars
{
sprintf(WorkText, "Time(pIndex)=%f", Time(index));
Print(WorkText);
sprintf(WorkText, "TimeCurrent()=%f", TimeCurrent());
Print(WorkText);
//return;
}
double myLow = Low( index );
double myHigh = High( index );
if( Low(index+1) < myLow && High(index+1) > myHigh){
insideBarIndex[ index ] = myLow;
} else {
insideBarIndex[ index ] = EMPTY_VALUE; // We do this in case we want tick by tick indication
}
}

Hi KelvinHand.
Thanks your Sample Code.
And You gave me the big hint about this problem.
I was sure that there is some problem in "IndicatorInterfaceUnit.h".
Because I hear that You were not able to perform the TimeCurrent() & Print().
I found the problem in "IndicatorInterfaceUnit.h".
| Code: |
I was fixing the bug in IndicatorInterfaceUnit.h.
###Before###
//-----Get current time-------------------------------------------------------
TDateTime TimeCurrent()
{
if (IntrfProcsRec.TimeCurrent = NULL) return 0;
return IntrfProcsRec.TimeCurrent(IntrfProcsRec.pTimeCurrent);
}
###After###
//-----Get current time-------------------------------------------------------
TDateTime TimeCurrent()
{
//if (IntrfProcsRec.TimeCurrent = NULL) return 0;
return IntrfProcsRec.TimeCurrent(IntrfProcsRec.pTimeCurrent);
}

Guys,
Thank you for your notes, i think that it should be changed to:
| Code: |
TDateTime TimeCurrent()
{
if (IntrfProcsRec.TimeCurrent == NULL) return 0;
return IntrfProcsRec.TimeCurrent(IntrfProcsRec.pTimeCurrent);
}
|
(i replaced "=" with "==")

This is still not fixed in version 2.9.3. 
These changes needs also to be done in strategyinterfaceunit.h
EXPORT void __stdcall ReplaceStr(PChar& dest, PChar source)
{
free((void *)dest);
dest = (PChar)malloc(strlen((char*)source) + 1);
strcpy(dest, source);
Change to:
strcpy_s(dest, strlen((char*)source) + 1, source);
}
int CreateIndicator(PChar Symbol, int TimeFrame, PChar IndicatorName, PChar parameters)
{
if (IntrfProcsRec.pCreateIndicator == NULL) return 0;
PChar IndicatorNameEx = (PChar)malloc(strlen(IndicatorName) + 4 + 1);
strcpy(IndicatorNameEx, IndicatorName);
strcat(IndicatorNameEx, ".dll");
Change to:
strcpy_s(IndicatorNameEx, strlen(IndicatorName) + 4 + 1, IndicatorName);
strcat_s(IndicatorNameEx, strlen(IndicatorName) + 4 + 1, ".dll");
return rec.CreateIndicator(rec.pCreateIndicator, Symbol, TimeFrame,
IndicatorNameEx, parameters);
free(IndicatorNameEx);
}

If you mean "strcpy", you will get a warning when compiling in Visual Studio.
By changing strcpy to strcpy_s (="safe"), you will suppress warnings.
If you mean "if (IntrfProcsRec.TimeCurrent = NULL) return 0; "
It means that IntrfProcsRec.TimeCurrent is always set to NULL.
By changing to "if (IntrfProcsRec.TimeCurrent == NULL) return 0; "
It means that if IntrfProcsRec.TimeCurrent is NULL then return 0

You should be try it once.
