Smooth MACD line

[Sam7768]

Hello All,

I have recently moved to TS to NT and NT coding looks very foreign to me. While I continue to learn the language, can someone please help me with a "MACD Indicator i.e line & signal line"...

1) That has MACD line (only MACD line) smoothened with 3 period EMA. Only the MACD line and not for the signal line.

2) And I am not looking for any Histogram.

Thanks a lot.

Welcome to our forums, I would suggest you step through those -

http://www.ninjatrader-support.com/HelpGuideV6/Overview18.html

For the code, you could use something like this -

 
double mySmoothMACD = EMA(MACD(Close, 10, 20, 1), 3)[0];

or this -

 
double mySmoothMACD = MACD(Close, 10, 20, 3)[0];

Thank you very much NT Bertrand.

In the below code, where to make the change?

Thanks a lot for your support.

Rgds,

For me second suggestion, you could just change the smooth input to 3 - this would give you the MACD value and it's 3 period EMA then, the histogram you could set to transparent color to not display it's values.
