Hello. I use this indicator and seems to be good for me. But it is a little bit confusing because the colors above zeroline are invers to the colors under zero line. Please change them in the right matter: all trend up in one color and all trend down same color.  Also I am missing the arrow signal at trend changing you describe above. Please complete the indicator. Thanks for your respond

Great indicator. Thank you for sharing. May i get source code of this indicator, please ?
