I'm experiencing a weird Volume problem with a few tickers.
As an example, consider the London FTSE 100 (yahoo symbol ^FTSE). For the last 10 daily periods, the volume on yahoo and in my AB database is as follows:
1,194,962,560 (Oct 24)
1,366,228,608
1,560,269,184
1,479,919,232
1,454,649,984 (Oct 28)
2,127,466,624 (Oct 31)
1,946,993,152
2,140,920,192
2,145,722,240
1,964,006,656 (Nov 4)
And these volumes plot fine on the daily volume chart. However, when I switch to weeky view, the volume plot is now plotting *negative* volumes. If I check this in AB explorer, the weekly values I see plotted which correspond to the above are:
-1,533,905,024
1,735,174,272
neither of which I can explain. As far as I can see, the values should be the sum of the relevant 5 periods:
7,056,029,568
10,325,108,864
Can anyone suggest what problem is going on here? I'm using AB 4.61 EOD and have reinstalled but the problem remains. All apart from a few tickers seem to be OK.
Thanks
