Calculating difference between 2 EMA's

[gcaldridge]

I am writing a strategy that includes checking the distance between 2 EMA's. I am only having one problem: being able to make the actual calculation. Every time I try anything I get an error related to incorrect field type.

All I need to be able to do is set a numeric variable to the value of an EMA.

Conceptually I need to be able to do the following:

EMASlow = EMA(34)

I have searched for hours for a solution for what I know is a simple problem but I had no luck. I'm an old VB programmer and finding all the details for C# is problematic.

If anyone can provide me the one or two script lines I would need, I would appreciate it.

What is the exact error message?

Hello gcaldridge,
Please open the output window (Tools>Output Window) and see if there is any error messages. If so can you please let me know.

Also please make sure you have enough bars to calculate on historical bars. Please refer to this post to know more

This is the code I have:

variable9 = EMA(14) [0];
variable8 = EMA(34) [0];

and it compiles clean.

When I add the following line:

variable7=variable9-variable8

I get the following error:

the name variable7 does not exist in the current context

Thanks

Hello gcaldridge,
To assist you further can you please send a toy NinjaScript code* replicating the behavior to support[AT]ninjatrader[DOT]com

Please append Attn:Joydeep in the subject line of the email and give a reference of this thread in the body of the email.

I look forward to assisting you further.

*The "toy" just means something that is a stripped down version that isn't necessarily the whole logic. It makes things easier to rout out.

Where have you declared variable7?
