Several private posts asked HOW to find if you have collected ticks for 12/31/98. My
suggestion is to go to the Server, select File and Portfolio and select an index you
collected in September, for example SPX. Click Edit Tick. If 12/31/98 displays you
have collected Ticks for 12/31/98 - which need to be deleted.
My TIMING numbers are off - apparently the timing is a factor of the number of symbols you
collect, not the size of 40bonn.dat Because I collect futures options and most indices,
I collect around 16,000 daily symbols so my times were longer.
One person asked what would be the implication of NOT deleting the bad ticks for 12/31/98.
I DON'T KNOW, but since Omega recommended deleting the Ticks, I presume it is possible on
12/31/98 there will be a MERGING of Ticks from the bad date in September plus good ticks
for 12/31/98 - which will be meaningless data. Perhaps Omega can answer that question
better.
