Great idea, but Omega should provide some reasonable recovery path
when the data is rendered useless by a (very) bad initial tick.

I don't remember questioning the correctness of any of your
many previous posts. I think you are wrong this ONE time.
If you've got the magic trick, please, let's hear it. Post it
to the list. All stock traders will love you for it (figuratively
speaking) :-)
I assure you changing the initial tick fixes only a few following
ticks. I did not count them, but the number Igor posted was 60.
Stopping and restarting a chart, all of TS, and/or the server
will not propagate the correction through the data for the day.

I happen to still have the "bad" INTC data for 1/5/98 saved in a
*.omz file. I will forward it to you (not the list, due to its
file size) momentarily. I eagerly await a second copy of the
corrected data and/or an explanation of how you fixed it. While
you're at it, please report how long it took to correct nearly
17,000 ticks. For the only way I know to correct it, you have to
edit something between 250 and 300 ticks, figuring out exactly
what value to use for each of them. Not hard, just tedious
and boring.
Of course you are welcome to ignore the data in the following
private message. But if you indeed have a quick scheme for
fixing the data, please do post it.
