Hey guys, I'm a noob with programming and I've hit a wall. When the SMI indicator has a bullish cross over, I want to define change the value of a variable. I know how to do that but I don't know how to tell the system if the SMI is bullish or bearish. I am using onfeed data and I've subscribed to the indicator but idk how to use the output.

like how do i tell the system, that when the smi line is above the signal line, define variable as 1 nd when smi is below the signal line, define var as 2 .
