I'm trying to convert .csv data to .t6 and then compare what I get while Test is running. .t6 format was obtained by slight modification of CSVtoT6.c script. For sanity check .t6 file was converted back to .csv using CSVfromT6.c script. The results look like that:

original .csv:
2011-07-01 07:16:00,90.5008,90.5485,90.5370,90.5008

2011-07-01 07:25:00,90.4557,90.4567,90.4590,90.4557

.csv->.t6->.csv:
01/07/11 07:16, 90.50080, 90.54850, 90.53700, 90.50080
01/07/11 07:17, 90.50980, 90.46890, 90.47080, 90.50980
01/07/11 07:18, 90.41970, 90.45030, 90.44630, 90.41970
01/07/11 07:19, 90.37470, 90.40560, 90.40380, 90.37470
01/07/11 07:20, 90.39270, 90.42290, 90.41690, 90.39270
01/07/11 07:21, 90.33870, 90.36490, 90.37720, 90.33870
01/07/11 07:22, 90.35670, 90.35680, 90.35350, 90.35670
01/07/11 07:23, 90.37470, 90.38390, 90.38460, 90.37470
01/07/11 07:24, 90.37470, 90.36920, 90.38120, 90.37470
01/07/11 07:25, 90.45570, 90.45670, 90.45900, 90.45570

So looks quite consistent. However when I'm loading the data by the following script:

void run()
{
StartDate = 20110701;
EndDate = 2011;
LookBack = 0;
BarPeriod = 1;
string asset_y = "RUBRUBSBER";
asset(asset_y);

double dates = wdate(0);
double *open = series(priceOpen());
double *high = series(priceHigh());
double *low = series(priceLow());
double *close = series(priceClose());
char line[100];

sprintf(line,"%f,%f,%f,%f,%fn",dates,open[0],high[0],low[0] ,close[0]);
if(is(INITRUN))
file_delete("Historyexport_data.csv");
else
file_append("Historyexport_data.csv",line);
}

the prices are modified and instead of 10 datapoints I get only 8 (first two are absent).

2011-07-01 07:25:00 90.457851 90.456703 90.459 90.457851

Any ideas of what I'm doing wrong?

Thank you in advance.
