there used to be a way to force a chart refresh using sc.InternalFR = -17;
this is no longer compiles. is there an alternative way to force a charge reload/recalc from ACSIL?

It looks like this does a "Recalculate" (Cntrl+Insert) - right?
If so, is there a way to "Reload and Recalculate" (Insert)?

Right.

A full reload of the chart data from the chart data file is not supported with a flag variable.

following this answer - when connected to a live feed, does SC continuously update the scid files for a chart as new data comes in? can I rely on it being up to date at any given moment?

Yes.

Actually, there is caching which is being used. The cache is flushed to the operating system when the chart updates.

Do you happen to have example code to start reading these files?

if anyone needs code that reads the scid file, see below...
the header and record structure defs are here: http://www.sierrachart.com/index.php?page=doc/doc_IntradayDataFileFormat.html

(there is a small typo in the header struct)


// get the file name from the symbol
  SCString filename;
  filename.Format("%s.scid", sc.Symbol.GetChars());

  FILE * fp;

  fp = fopen(filename.GetChars(), "rb");

  s_IntradayHeader header;

  if (fp == NULL)
  {

    return;
  }

  fread(&header, sizeof(struct s_IntradayHeader), 1, fp);

// we have the header, now read the records

  s_IntradayRecord rec;
  while (fread(&rec, sizeof(struct s_IntradayRecord), 1, fp))
  {
   // do something with the record
  }

  fclose(fp);

You can get the path and filename for the intraday data file with:
sc.DataFile

the dates in the scid file are with MS timestamps?

There is a millisecond component to them, yes.

when you write/update scid files in real time, do lock the file? do you lock the whole file or only the region that you are writing to?
