Dear Raymond,
Thank you for sending us your message. We adjust our historical price data to remove the effects of fund distributions, dividends and stock splits from our charts. I suspect that is the reason for the data differences that you noticed.
Splits, distributions and dividends are "artificial" changes in the price of a ticker symbol that create gaps on technical charts causing misleading signals from technical indicators. To eliminate those gaps, we decrease our historical prices (and increase our historical volume data) in a way that removes these misleading signals.
For more information about our data adjustment policy, please see this article:
support.stockcharts.com
In addition, we now offer special unadjusted ticker symbols for most stocks and ETFs. To see a chart of unadjusted data, just add an underscore character to the front of the stock's normal symbol. |
