I'm trying to add a simple background color when on a stochastic, k crosses over d any time but when k is above 80, and equally k crosses under d any time but when k is below 20.
Yet constantly I'm getting crossover and crossunder signals in these condition. In this case in the picture there is not ever a crossover at all.
Can anyone help me explaining why this happens?
Thanks
