Ticks + Volume

[Kim Horn <kim@xxxxxxxxxx>]

I need to historically test a tick based system. I
have the data in the following format:

"Date", "Time",  "C", "V"
09/15/97,08:30,93.64,20
09/15/97,08:30,93.64,15
09/15/97,08:30,93.64,10
09/15/97,08:30,93.64,20
.......etc....

I need the volume and price information. 
I have tried importing into Tradestation but I 
only get the Price; no Volume. Should
I be able to read in the volumes too ?

Any suggestions

Thanks
Kim Horn
