With prompt "Retrieve Prices for 34 of 460 symbols" then just the 34 symbols were put in the idc symbol file(symidc.prn).The prices for the other securities may have been retrieved and remembered from an earlier time.
Prices only need to be retrieved once for that date for all entities.
Let's try to isolate the problem.
1) Look in the lastest price file(apr2.prn) and see what symbols were retrieved. In Navigator Access, select View |Price file. If this contain just the 34 symbols then only the prices for the 34 symbols were retrieved.
2) Or look in log file (wdci.log), select View | IDC Log File. This is a log of the communication. It will list the packet sent and retrieved for each symbol.
Also the location of the IDC price file(idc.prn) and IDC symbol file(symidc.prn) will be shown. If the path is incorrect then this could be the problem. If FN or Navigator Access has been installed in a different folder then the path needs to be corrected. Either reinstall Navigator Access in the FN folder. Or correct the path in the WDCI.ini file. Go into test mode of Navigator(Help |About NA & press letter "t"). Now on the View menu select WDCI Ini File. In the WDCI.ini file correct:
default_dir=C:\FN\
home_dir=C:\FN\
to be the path to the FN program folder.
Verify the input file and output files are:
inputfile=symidc.prn
outputfile=idc.prn
Note: these names may be incorrect if another version was installed directly from IDC.
Let me know if this does not solve your problem.
