Hi, I understand to get non-adjusted price series in conventional QCAlgorithm, I should use:

SetDataNormalizationMode(DataNormalizationMode.Raw);

However, under QCFramework, how should I implement this setting? Example code below, how should I ensure the symbol added is Raw price data?

var symbols = new [] {QuantConnect.Symbol.Create("SPY", SecurityType.Equity, Market.USA)}; SetUniverseSelection(new ManualUniverseSelectionModel(symbols));

Thanks!
