One thing I noticed is that if you use a custom chart bar function loaded on a chart, then the extracted datetime follows the time zone of the chart, but when you do a direct extract from the scid file, then the time is gmt/utc. The C++ commands to use in a {SCCustomChartBarInterfaceRef ChartBarInterface} function could be these: SCDateTime tTime=ChartBarInterface.NewFileRecord.DateTime; long long tickTime=reinterpret_cast<long long&>(tTime); tickTime/=1000; // to get rid of microseconds, which are trade numbers tTime can be used to get all sorts of data out of the SCDateTime constant reference, e.g.: double xlTime=tTime.GetAsDouble(); And this is all easily done in ahk as well, with commands like this: hdr:=56,numBytes:=40 scDateTimePosition:=0 scPricePosition:=12 ; scDateTime position (int64) - 0 bytes in fo.Pos := hdr+(A_Index-1)*numBytes+scDateTimePosition scDateTime := fo.ReadInt64()//1000 ; get rid of trade number dtetme := 18991230000000 dtetme += scDateTime//1000,seconds dte := SubStr(dtetme,1,8) ; scPrice position (float) - 12 bytes in fo.Pos := hdr+(A_Index-1)*numBytes+scPricePosition floatPrice := fo.ReadFloat() |
