If you are trading a system, in my opinion I feel like you should follow the system to a T but keep a profit target in mind. It also depends on how much capital you are working with. You have to be realistic about your profit and losses when it comes to account size. How much are you willing to risk and what is your average profit following the system's every trade. I would make my profit target around the average of how much the trading system usually makes.
Thank you Guzman Katherine,
Since I initially posted, i still struggle with this a bit since I past posted.
For now, risk vs reward of 1:1 per trade and Not take every system trade as my account is still small ($4000 to $5000). I tried taking every trade the system offered and felt I was trading too much, but still good results.
I really don't have an answer for my problem. Overall taking every trade should results in good roi over time, but manually doing it everyday for 8 hours starring at screen is a bit tiring. It's something I have to get use to. Because my account is a bit small, i am focusing on getting right setups early as possible and making money to build account.
I know i have a $1000 loss limit per day I will not go under. I will take it day for day. Some days I take every trade, some days I dont.
