'SHA256Managed' is obsolete: 'Derived cryptographic types are obsolete. Use the Create method on the base type instead.' (https://aka.ms/dotnet-warnings/SYSLIB0021)

'IndicatorBase' defines operator == or operator != but does not override Object.GetHashCode()

'IndicatorBase' overrides Object.Equals(object o) but does not override Object.GetHashCode()

'AccumulationDistribution.WarmUpPeriod' hides inherited member 'IndicatorBase.WarmUpPeriod'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.

The type name 'kek' only contains lower-cased ascii characters. Such names may become reserved for the language.

Identifier expected. See also error CS1001.
