Sorry but I cannot tell you when to exit. If you play 1 contract you would exit differently to a person that play 3 or more. It all depends on your style.
I guess really what i'm wondering what it takes for you to call the trade a winner? if it moves 1 tick off your entry point, is that a win? Is it a minimum of two points?
This is not a scalping system so I would not count 1 or 2 tics as winner. In order for me to count setups as a winner I need it to have at least 1:1 risk to reward ratio from my stop. So for example, ES have 2.5pts stop, I need ES to move 2.5pts to count it as a winner.
