Elder's Impulse indicator

[nandradev]

Hello, I have been working with metatrader but new using ninja trader, I have been using this indicator I found in another forum, I wish to know if there is anybody cappable to translate this mt4 indicator to NT, this indicator works with an EMA and MACD Histogram, when MACD Histogram slope is up (slope up means two bars, if the last bar is higher than the previous one; and slope down when the last bar is lower than the previous one, no matter if lines are above or down the zero line), and the EMA slope is positive, it bar will be blue; if EMA slope is negative and MACD histogram is down, it bar will be red, and in other case will be gray.
changes in parameters like MACD and EMA can be done.

I have attached an image of how does it look like.
Thank you

this is the needed indicator language:

Welcome to our forums and thanks for sharing this source code - please have a look at this thread where the same indicator was developed (at least it should come close I believe) - http://www.ninjatrader-support2.com/...ead.php?t=6160

thank you

thank you bertrand, is almost what I am looking for, I send a message to wessel, asking for help with this indicator, thank you very much
