@readnow, For what i could see, It shows the BUY values some minutes after we pass a certain time frame. Like per example, there's no buy label at 19:00, it's 19:30 and then it shows a buy label at 19:00.
@Gornidah, I didn't make it that way.
It just wanted to see a line linking the previous high and low points.
The lines are intended to find resistance and support lines.
I'm sorry to have misunderstanding you to expect something big.
