Need code to round double value to integer value

[Tagliareni]

I want to create a MACD in which the only user input is the slow EMA and the fast EMA is automatically calculated as 90% of the slow. For example, if the user sets the slow EMA at 200, the fast will automatically be calculated as 180.

Can anyone share any code that will help? Maybe something that will round decimals to integers or convert double values to int values.

I apologize if I'm not using the correct terminology. Thanks for the help.

Hello Tagliareni,

Thank you for the post.

You could do this by replacing the existing Fast property to multiply times 0.9. You would also need to remove the line in State.SetDefaults which sets the Fast to have a default value. Your properties would end up looking like the following:

[Display(ResourceType = typeof(Custom.Resource), Name = "Fast", GroupName = "NinjaScriptParameters", Order = 0)]
public int Fast
{ get { return (int)(Slow * 0.9); } }

[Range(1, int.MaxValue), NinjaScriptProperty, RefreshProperties(RefreshProperties.All)]
[Display(ResourceType = typeof(Custom.Resource), Name = "Slow", GroupName = "NinjaScriptParameters", Order = 1)]
public int Slow
{ get; set; }

I look forward to being of further assistance.
