Hallo,
better ask the fellow users before I do some serious damage.
I have a db set to 1-min frequency
latest year data ('05) is loaded as 1-min data
year before latest is loaded as 10-min data
year before is 1-hour data
and so on...
This is because I thought I would have had difficulty
loading/backtesting more frequent data from the past, moreover I
didn't have that data at that time
now: I found 1-min data for '04, and I also saw that performance is
not that much of a problem...
1. what happens if I just import again '04 in the db at 1-min level?
2. will it overwrite previous 10-min data or will the system keep both?
3.In the last case, is there a way to batch-delete quotations?
Kthx,
neuro
