EMA of an EMA

[jhooper]

Hi,could anyone help me please?
Despite spending several hours trawling through the help documents and the indicator forum, I'm still none the wiser as to how to program this custom indicator.
I'm trying to calculate (and plot on the price screen), a ten period exponential moving average of a 5 period exponential average of the close. ie an EMA10 of EMA5(close). I can happily set up the first EMA5,but I'm not sure how to reference this first EMA in a second custom indicator?

Any help would be appreciated,
Thanks,
John

Create a new custom indicator via the wizard, once done you will have the NinjaScript Editor open.

You should see something like:

Plot0.Set(Close[0]);

Replace that with

Plot0.Set(EMA(EMA(5), 10)[0]);

thank you!

Many thanks for your help Ray!
That works great and is simpler than I thought it was going to be.

My next task was to use the Typical price formula for the E5 (and leave the E10 as the close of the E5.
Using the help documents, I managed to get this to work:

Plot0.Set(EMA(EMA(Typical, 5), 10)[0]);

As I say,it works and compiles.Having looked at the help notes I wasn't quite sure if I had done it right.
Does it look ok to you?
Thanks again Ray,
John
