I don't work nor have I studied trading to the extent that I'm familiar with the different charts and how they work.

I was also confused about the time interval setting, but became clear that as opposed to bitcoinity (where you see the bitcoin timeframe), the timeinterval refers to the "candles/trends".

The bottom staples are just referring to volume of the candles.

The only thing that I havn't grasped is what the 2 linear lines represent - one brown and one blue?
