Why do these 2 calls produce different results of SPY when I use the same History call?
AddSecurity seems to be returning incorrect data.
AddSecurity(SecurityType.Equity, "SPY", resolution: Resolution.Daily, dataNormalizationMode: DataNormalizationMode.SplitAdjusted);
var spyPrices = History<TradeBar>("SPY", 2, Resolution.Daily).ToList(); AddEquity("SPY", Resolution.Daily, dataNormalizationMode: DataNormalizationMode.SplitAdjusted);
var spyPrices = History<TradeBar>("SPY", 2, Resolution.Daily).ToList();

Hi John Gillespie ,
Thank you for the report!
I have created a GitHub issue to address the problem:
