Hi all, since I am new here and couldn`t find the answers yet.. I would like to tap your expertise.
What I want to do: I want to run strategy backtests on daily bars (mainly US stocks) with more than 25 years of history.
My question: How good is the built-in data in WL? Which data feed would you recommend if I do not need streaming quotes, just EOD.

Wealth-Data covers only large caps there are or were part of the S&P 500 and Nasdaq 100.

If you need more than that, then don't even think twice and get a paid subscription to Norgate Data for trouble-free, auto-updating and managed data, with historical watchlist backtests for even the Russell indices.

See the Norgate Extension for details.

Why should you use Past & Present symbols for DataSets?

thanks a lot! What is the source of the available data (SPX and N100)? Can I rely on it when I just do backtests with these two sets?

Be more specific.
Excluding the Crypto providers (Kraken, Binance, KuCoin, CryptoCompare), you can use any of these as a source for that data.



If you want to backtest only the S&P 100, S&P 500, and Nasdaq 100 with Daily (end-of-day) data, then our Wealth-Data is the best choice in my opinion.
Why? See the FAQ at https://www.wealth-data.com

Sorry for not being precise enough. I want to make sure that my backtests are reliable so the question is: Do I need an additional service like Norgate if I focus only on SP500 and N100 on a daily time frame? Is the quality of WealthData good enough?
