Non-nullable property 'Activity' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the property as nullable.

Non-nullable property 'Symbol' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the property as nullable.

Non-nullable property 'symbolName' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the property as nullable.

Test methods should not call ConfigureAwait(false), as it may bypass parallelization limits. Omit ConfigureAwait, or use ConfigureAwait(true) to avoid CA2007. (https://xunit.net/xunit.analyzers/rules/xUnit1030)
