It seems good. 

I like it, but an explanation of the indicator would've been nice! What are the purple lines trying to tell and what are the grey lines supposed to tell and last but not least what are the red lines telling? I use it in conjunction with a zigzag channel and I trade somewhat better, but a description and understanding of all coloured lines would be perfect and make for easier decision makings and trading! Could you please assist because I'd like to use this daily and should I understand it better I'll become a much better trader because it's a great indicator! 

Спасибо за индикатор!  Есть одна проблема, не окрашивает бары, хотя функция в настройках включена. Как можно решить проблему?

Excellent indicator cannot believe is for free
