Hi Ajax,
I would like to thank Varunji for his selfless service and I am learning through his posts and am a beginner.
I am linking VKji's thread. Start reading from this page and you will understand. There has been an AFL provided by Extremistji in the same thread.
According to my limited knowledge the discussion of LV bar starts after this page. Keep reading the entire posts and you will get some understanding.

Hope I have provided you the right link for start.
