I was just downloading daily history last night and came across a problem with 3 stocks: CNBF, C.SGS and CAOP. I was requesting 200 days of daily data for the above mentionned symbols and this is what I received:


1. C.SGS,2005-01-26 03:47:16,0.1000,0.1050,0.1000,0.1050,34000
2. C.SGS,2005-01-26 03:47:16,0.0800,0.0800,0.0800,0.0800,29000
88. C.SGS,2005-01-26 03:47:16,0.0200,0.0200,0.0200,0.0200,40000
89. C.SGS,2005-01-26 03:47:16,0.0000,0.0000,0.0000,0.0000,0

1. CAOP,2005-01-26 04:05:38,4.5000,4.5400,4.3000,4.3000,68370
2. CAOP,2005-01-26 04:05:38,4.5500,4.5500,4.5000,4.5000,3100
156. CAOP,2005-01-26 04:05:38,0.3500,0.3500,0.3500,0.3500,100
157. CAOP,2005-01-26 04:05:38,0.0000,0.0000,0.0000,0.0000,0

1. CNBF,2005-01-26 04:34:36,12.7500,13.0000,12.7500,13.0000,1400
2. CNBF,2005-01-26 04:34:36,12.5000,13.0000,12.5000,13.0000,4655
83. CNBF,2005-01-26 04:34:36,11.7500,11.9500,11.5000,11.9500,3200
84. CNBF,2005-01-26 04:34:36,0.0000,0.0000,0.0000,0.0000,0

The interesting thing is I get the same result if I request a number of days equal or greater than the max numbers above. But if I request 1 day less than this I get what I expected which is 88 days of history for C.SGS, 156d of CAOP and 83 days of CNBF.

Any idea why? Of all the stocks I downloaded last night these were the only 3 with this behavior. Aren't they special!

I am seeing this too. It looks like something of a corrupt datapoint in the chart database. Will get our MDI group to look into it on Friday.
