I am trying to execute a trade after two moving averages cross each other not immediately but as soon as they are 4 pips away from each other. I know that this can be done in the adjust field of the condition. My question is....

Do I use a positive value for crossing above and a negative value for crossing below? Please refer to the screenshot. Am I working correct?

I created a terminal variable called "eq" which represents the account equity and a variable "lev" that represents the account leverage.

I want to utilise them in a formula to get a trading volume. I want to put it in the formula mentioned below. Where can I put it?

vol = (eq * lev) / 20
