Price/Volume Data Accuracy

Description of work

Describe the work to be completed:
The time series charts on the Stock & Fund page need to be examined for accuracy across the different data provides, which at the time of writing this include: AlphaVantage, FMP, and Yahoo Finance (community version). Although the data mostly appears correct, there seem to be issues with some of the time series charts. For example, the AlphaVantage data for the 5Y interval is showing strange numbers for some companies with extremely high prices that were never reached in reality, followed by sharp drop offs back to the true values. The Yahoo Finance seems to have issues with the intraday data as well (i.e., 1D interval).
