Re: [amibroker] Trendline Data

<? Partial Solution ?>

Suppose the trend line's Study ID is "UP" and Chart ID is 1131:

 

TrendLine = Study("UP",1131);

outfilename = "C:\\Temp\\TrendlineData.csv","w");

headerLine = "Datetime, Trend\n";

 

fileHandle = fopen(outfilename);
if (fileHandle) {

   fputs(headerLine);

   bi = BarIndex();

   selectedIndex = SelectedValue(bi) -  bi[0];    // not going to loop from 0, but for a certain selected bar relevant to the trendline's start

   dt = DateTime(); 

   for (i = selectedIndex; i < BarCount; i++) {

       ds = WriteVal(dt[i], formatDateTime) + ",":  // Write the date time string (x)  

       qs  = StrFormat("%.2f\n", TrendLine[i]);   // Write the trend line's data  (y)

       fputs(ds,fileHandle);

       fputs(qs, fileHandle);

   } 

   fclose(fileHandle);

}

Subject: [amibroker] Trendline Data

Does anyone know if it's possible to export or write trendline data to a text file? Ideally, whenever I draw a trendline on a chart, I would like the data to be written to a text file (or I can batch it EOD) so that I can have another application parse the file to get daily trendline levels for each ticker. Currently, I can run a scan on anything that I tag "RE" or "SU" to get trendline breaks, so that data is stored somewhere, I just don't know if/how I can access it and if there is a way to setup a process that auto writes it to a file. Anyone know how I can set this up? Thanks.
