System gives you an edge and plan; you still need to bring discipline and your baggage, which ultimately determine your profit and loss. We all trade NERS with our own comfort and flavors. But every one makes different profit. You need to be in your comfort zone, If stop loss make you comfortable then use that. I do not trade for the day if I have 3 losses in a row. Is it draw back of system? to some extent it could be, a lot of talented people trade for living so market participant change there mind and act simultaneously no indicator can tell you that. At that moment you just take what is given to you.
My every trade can not be profitable that is where I start. If I am afraid of loss I can never enter in a trade. I just need to determine what loss I can take comfortably and what could be reward. Those who trade for adrenaline rush they end up broke.
I apologize if you feel bad about any thing I have written. IMOP if we analyze our personality and see weather we could be a trader or not that is a good start other wise it is better to give our money to a good money manager. I do not post much because most of the people here are better trader then I and they always give better advice.
I just trade, and I do it for living.
Good luck.
