Hello all,
after Dusktrader's excellent trading script, I wa eager to create some other strategy's. Come to find out, I don't have access to the history that I need from my trading account with Finfx. I don't have a fxcm account so I went to histdata and downloaded a sample of their data.
the data is formatted as follows:
Row Fields:
DateTime Stamp,Bid Quote,Ask Quote,Volume
DateTime Stamp Format:
YYYYMMDD HHMMSSNNN
Legend:
YYYY – Year
MM – Month (01 to 12)
DD – Day of the Month
HH – Hour of the day (in 24h format)
MM – Minute
SS – Second
I've attached my script which doesn't seem to be able to move the open,close,high and low to the TICK structure and doesn't seem to create the .bar file. It also aborts after the third time thru.
I'm out of ideas. Would appreciate any help any one can bring.
Thanks

//convert History downloaded from
www.histdata.com//download each year, change in excel to use a comma delimited file, if not already
//sorted so the latest entry in first as required by zorro.
//This script will read the file defined in the script, convert the records to Zorro's
//format and then write them to a binary file name export.bar to be used by Zorro.
//youo can then rename the file to the Zorro .bar format.
//the format of the histdata.com file is DateTime,Open,High,Low,Close,Volume
//the format for zorron is the tick stru included in include\trading.h
//including OLE Date.counting days since midnight 30 December 1899
//typedef struct TICK{ float fOpen, fClose; float fHigh, fLow; DATE time; // time of the tick in UTC time, OLE date/time format} TICK;
//
//the timezone for the histdata.com files is EST without daylight savings time
//so the conversion must take that into account
