result

code: 

[Parameter("MaFast",DefaultValue= 2)]

public double maFast {get; set;}

ma=Indicators.SimpleMovingAverage i_ma;

 'ma=maFast.Result.Last(0);'

Error :    'double' does not contain a definition for 'Result' and no accessible extension method 'Result' accepting a first argument of type 'double' could be found (are you missing a using directive or an assembly reference?)   

Not Sure why the error. your help will be appreciated. Thank you
