Hey ap4god,
anyone can give you an advise on that, not just Edward
First off, let me ask, how do you place a trade? You should certainly know where to enter, e.g. what is the best spot to enter, right..?
If not, then I can't imagine someone being profitable by placing trade chaotically.
If you, and I'm sure you do, know where to enter, then one of the Reasons of entering at the chosen spots would be a Good Logical place to set a stop: something like a Swing low/high, or a Pivot, or a trend line, or any other reference you'd use.
So, what i'm trying to say here is that you probably do have the skills of placing stops, and may be its something more specific you wanted to learn.. Because your initial post is so general beyond imaginable, that only a few people like me would be interested to try to answer it. Don't get me wrong
Fibo.. fibo.. I think I saw someone referring to this website, try it:
