Re: Final Proposed Data Format

[Howard Jackson <hrjf4@xxxxxxxxx>]

Doing a quick test filling a file with the following
ticks
   19990101,120000,100.125,10000,1
with my notepad.exe I got the following numbers:

# Records      HD space taken by file
10             1KB
100            4KB
1000           36KB
7000           249KB

So if we collect 20 days of 500 symbols that trade
approximately 7000 ticks a day, we would end up with
something like a 2,480,000KB of hard drive
requirements.   Is that 2 thousand gigs of hard drive
space? oh my! am I missing something?

Good luck Mark... and BTW, why the hell are you
posting this here?

Note: I was using Win98 with FAT32 in the computer
which I ran the test.
