When you add the script to your chart look for a gear symbol near its label on the chart upper left side. When you press the gear symbol you it choices, look for a list that includes stop loss, trailing stop, limit (profit). That is where you enter that information.

The +- is the amount long or short. I dont remember if I was using USD or contracts when I published this script.
