Quote from djmartin:
IMO risk reward is one of the most misunderstood aspects of trading. Of course we all want to risk 1 to make 2 or above but what if the market don't allow that to happen. Lets say you put on a long and your risk reward 1-3, markets starts to go in your direction, so far so good. All of a sudden your see a big buy come in and the market doesn't go bid, instead it pauses. Then a big seller steps in and the market jumps 2-3 ticks down. At this point in the trade your up say 1, what do you do, A) stay in the trade because your risk reward is 1-3, B) take your profit and let them battle it out, C) Do nothing and say to yourself I'll rather get stopped out then brake my trading rules, or D) take some off the table so the pressure is off then see what happens. My answer is D. The beauty is there's no right or wrong answer but the professional intra day traders i talk to don't pay a lot of attention to risk reward like you think they do. They take what the market gives them. In the above example if the market goes another 2-3 ticks against that bigger buyer he's going to probably cover which will lead to more downside action, why would you want to stick around because some trading book told you you much have a risk reward of 1-3. This is just my opinion. I know theres more than one way to trade.
