3 pips is no good as a stop. You will be stopped out in seconds.

A 30 pip stop is more useful, but it depends upon the volatility of the traded fx pair. What timeframe you are in etc. They all have different characteristics. It also depends upon what has happened so far when you enter a trade. Where are the Bollinger bands? If they have been in a narrow band for more than half a screen's width (as a very rough rule of thumb) then you may expect a breakout at any moment, (but in which direction?) but most likely to be timed around a news item. Read the daily predictions from SirPips and Crazy Cat.

Are you approaching a support, pivot or resistance level, where the trend may reverse? Do you adjust the stop to take this into account?
Which part of which wave are you in?

Read the general scenario descriptions from DailyFX and Askjeffwild.com compare them. Add in the FPA info. The guys who do this for a living may spend hours each day to keep up with likely trends, reactions to events and long term strategies. Some guys on here used to be professional traders maybe they will say how long you need to study each day, that is once you know everything about the market .

There seem to be a notable number of people who post in the forum with incredible no fail systems, they publish their results for several weeks then they disappear. It's not easy, some people have a lot of lucky trades (or coincidence of their system working) in succession but luck runs out. Some systems work for some people for some of the time but come unstuck when conditions change.

Going back to your original proposal; Derren Brown, the illusionist/showman/entertainer showed on UK tv how to throw heads 10 times in a row which he demonstrated in one continuous take on tv. He also showed an infallible system for winning a bet every chosen horse race. How did he do it? The answer is entirely logical.

42 is the number.
