To avoid casting to and from the dynamic type, you can use the Get<T> method to access the dynamic member and return the object with its type.
// Get the SPY Equity object from Securities to get the EMA indicator and its current value
+var ema = Securities["SPY"].Get<ExponentialMovingAverage>("ema"); // The type of ema is ExponentialMovingAverage
+var emaValue = ema.Current.Value; // The type of emaValue is decimal
+If the type or the member name is incorrect, the Get<T> method causes a runtime error.
