Hi John,

Thanks for the speedy response. I have followed the instructions, see attached images presenting identical data:

Live Data:

Delete and Redownload:

A few observations:
- The data or calculation method that Sierra collects / uses when it is connected to live data is different from the data collected from the server when the indicator is not attached.
- To put he idea into practice, I have chosen a day were the indicator was not connected to the chart and subsequently gone through the same process outlined in your prior message. Notice that the data remains unchanged similar to the above screenshots.

Downloaded data (indicator not attached to chart on the day)

- I also found the area where I logged off yesterday and noticed the data change again. Having deleted and redownloaded the data, I was again left with the contrast in data between live and downloaded. I take taken two screenshots as it is challenging to show both with the same detail given the difference in scaling / size.
