Qstick V2
this is the Qstick as described by Tushar S. Chande and Stanley Kroll and post from AleksandrLombrozo , so all credit for this code going to him. I just add the option to change both of the sources (close , open)
//@version=2
//Can choose the source to apply
study("Qstick V2")
src=input(close,title="source 1")
src1=input(open,title="source 2")
lenght=input(defval=8,title="length_Qstick", step=1)
difference=sum(src,lenght)-sum(src1,lenght)
ema_input=input(defval=5,title="length_ema", step=1)
ema=ema(difference,ema_input)
plot(difference, color=red, linewidth=2, style=histogram)
plot(ema,color=blue,transp=20)
