@rayo - I have submitted this to engineering for correction. Thank you.
A fix has been put in place and the data for TPR should be updated by tomorrow morning.
The data copy from COH to TPR was not done correctly. I see 66 trading days where the O(pen) and L(ow) prices are way off (too low). Not sure how that could happen since it's just a simple copy. It just seems like the OL prices were just randomly filled in on those dates.
This seems to be a symptom of a larger problem. I pasted screenshots of 5-Sep-2017 data to show the problem data between old COH and new TPR. However, when I display only the date of 5-Sep-2017 for TPR it shows the correct data and it also downloads correctly. However, when displaying/downloading a range that includes that date it is incorrect. I can't explain it.
I compared the original COH price data in YF with TPR in Google Finance and it is very close on a large majority of trading days. If you can just get the YF COH data copied over to TPR correctly this issue could be closed.
Thanks for the screenshots. I don't have an update right now, but I passed the info along to our engineers.
This is a comparison between what the chart should look like for TPR using the original COH data and the corrupted data currently under TPR.
I passed this along. Our engineers are aware and still looking into this. Thanks.
