Declaration of Generic Indicator

[ivb73077]

Hello,

I am developing a strategy where the user may elect EMA/HMA/SMA as their moving average type.

I would like to declare a variable that is then assigned to the moving average type selected by the user. For example:

XXXX myMA; (where XXXX is the variable type)

If the user selects EMA, myMA is converted from a generic indicator type to EMA. If SMA is selected, myMA becomes a variable of type SMA.

Is there a generic indicator class to which I can assign myMA before it gets assigned to the user-selected MA type?

Thank you.

Hello ivb73077,

There is not a generic indicator type you could cast this to. You would need to cast this as the indicator type it is.

SMA mySMA = (SMA) SMA(14);

EMA myEMA = (EMA) EMA(14);

You can always use a base class as a generic declaration for an inherited class. So, it is not a NinjaTrader supported method, (caveat emptor), but you can declare XXX as IndicatorBase.

This is exactly what I was looking for.

I was not clear what type to declare the generic case because I did not know about the IndicatorBase class. Thank you.
