Hi guys,

I need some help about write a study in Sierra Chart.

I have this code :

#include "sierrachart.h"
SCDLLName("ReadFile_Study")
SCSFExport scsf_ReadFile(SCStudyInterfaceRef sc){
SCString DebugMessage;
SCInputRef FullPath = sc.Input[0];
if (sc.SetDefaults){
sc.GraphName = "ReadFile_Study";
sc.AutoLoop = 0;
FullPath.Name = "Full Path to Text File";
FullPath.SetPathAndFileName("");
return;
}

std::ifstream input(FullPath.GetPathAndFileName());
for( std::string line; getline(input,line); ){
DebugMessage.Format( "line : %s", line.c_str() );
sc.AddMessageToLog( DebugMessage, 0 );
}
}

The first step is done ! Read a csv file.

The second step it's draw a line in SC of this data.

my file is by example

0
0
0
1
0
0
1

etc etc.

Someone can help me to write the second step please ?

You should upload the file you are trying to read and plot. Because it looks like there is no index or time stamp so what will that relate to on the chart?

Hi,

What do you mean by "You should upload the file you are trying to read and plot." ?

I have control over the input file so I can add an index (value or Date)

I just try to plot in subgraph my indicator (0/1)

Ok but how are you going to match it to the bars in the chart?

Each line in my file corresponds to a bar in my graph.

Geez your not giving much detail to make it easy to help. What I'm asking is if you have a file with 100 different values (1s and 0s) and want to apply it to a chart, say for example a 1 min chart, and that chart has 500 bars how are you going to align the data?
