what is the yellow line for?
Andreas Sachs  
I have the same question as Lena. My guess is that the yellow line marks the neutral level. The market trend is difficult to determine. These are just my presumptions. I will be grateful for the short information. I am very happy after the first week of use. But what I like the most are the proprietary and rare solutions and the approach to the analysis of Qiuyang Zheng.
