I'm trying to import from "SieraCharts" 1minute bars (DAX-future) into Zorro,
for that I adapted Convert.c and created DAX_2017_06_1m.bar which worked well;

at least it seems so because ZHistoryEditor has no problem to show this file
then I inserted the file in AssetsCur.csv and tried to run this little script:

function run()
{
set(LOGFILE);

BarPeriod = 1;

StartDate = 20170511;
MaxBars = 12000;

vars Open = series( priceOpen( ) );
//vars EMA_30 = series( EMA( Open, 30 ) );
//vars EMA_300 = series( EMA( Open, 300 ) );

printf( "nBar %i of %i", Bar, NumBars );

//TakeProfit = 10;

/*if ( crossOver( EMA_30, EMA_300 ) )
enterLong( );
if ( crossUnder( EMA_30, EMA_300) )
enterShort( );*/
}

I get these error codes:

Bar 0 of 0
V 1.580 on Mon 17-06-12 16:27:54
Error 055: DAX_2017_06_1m 2017 price history missing
Error 055: no DAX_2017_06_1m 2017..2017 prices
Error 055: No DAX_2017_06_1m prices

any ideas?
