Trend Magic

Hi

I like this indicator.

Can you add bot function which will buy on green and sell on red?

Rgds.

In the first place, I was very impressed by the implementation of the Belkhayate in the signal indicator you provided. The GUI is giving a very helpful assistance during the stressfull trading hours. I am following him for several years and I believe you have done something quite unique. As I am mainly trading very volatile commodities, trend magic based on CCI was something I definitely want to look into details. I think it can replace both Supertrend and/or ATR trailer as it shares the methodology but it's instead based on CCI rather than the data series itself. I just added minor options to help me with super volatile commodities and also in a way to bridge Trend Magic with those two previous indicators. I am using the normalized version of the ATR.but aside that modification the default values won't change the original version behavior.
