Dev,
To trade these Lines (the exact value is in the upper task bar),see the periodicity ,here it is 10 mins,wait for few bars , see whether it is breached from downside or upside,if so how many times,these are levels when sentiment change will happen,now when we get a directional bias (watching few bars) we initiate trade for few more bars towards the sentiment change,keeping Stop above or below these lines,often that gives a minor rally.
As it is my subjective code hence the success is absolutely uncertain,hence trade on your own peril.
