A cloud based on the highest high and lowest low of a given period (Donchian), same lines used in Ichimoku Cloud (Conversion line or Base line).
Short term line is based on current time frame, long term line is based on your given multiple of current time frame. The color of the lines is based on up or down movement.
I have not used this in my trades (yet) so I don't know how good it is, just posting because it looks nice :) Feel free to share your settings if you can find good ones.
