I have not seen a "system" where you can say for certain, "if price does this, then I will do that" every time and have it make money. I would venture to say that most traders who have a "system" or "plan", have, as a strong element in that plan, their own intuition.
For example, you could look at Joe Ross's 123 and RH trading, and it looks good, but if you trade it every time, you will loose money. You have to have that little extra that says, "this is a good one" or, that one doesn't look so good, I will pass". I have seen many traders say, "Look, if price does X at such and such a level, then I will do Y and over time I will be a winner". I would look at the chart and say, why not when it did just that back here, why did you pass on that one? Sometimes there is a good answer, but often the answer is, "it just didn't feel right".
This make the whole concept of a "plan" hard to grasp. A "plan" implies having a set of rules you follow every time, but I think intuition plays more of a role then even the successful traders realize.
Trader Vic, in his first book, said he mentored 35 traders. Had them in his office, gave them access to everything he had including his watchful eye and detailed advice. In the end only 5 managed to be successful.
I know there are some mechanized systems that do OK most of the time, but I think here we are talking about trading at a human level.
