About the Stocks financial data sources

Once upon a time Robbie posted a comment about the quaility of historic price data from providers varies including error.

After using this Data Provider I now understand better and have more respect for anyone attempting to make it work.
Also understand why different database lookback testing results will not likely exactly match.

Fundamental company data, historical data, real-time and delayed prices, fund summary and performance data are provided by LSEG Data & Analytics.
Use of LSEG Data & Analytics data must be in accordance with the Microsoft Service Agreement.

I used just Excel to match market-days and Days without coding. And it requires adjustments for holidays and data type.
