For the traders who refuse to post their strategies - I make no judgements as to whether you are right or wrong. But I hope we all see clearly what are our motivations and obstructions.
Firstly, there is a linkage between hard work (developing a strategy) and success. Which seems strangely puritanical amongst a group of people who are currency traders. Religious movement of various colours have placed hard work as a virtue. But generally they meant as a virtue for the society as a whole. Very few religious movements have elevated personal profit and wealth to the highest esteem, whether it came from hard work or not.
Secondly, knowledge gained from hard work is something you can give away and still retain. So although if you grow a lot of grain and give it away, you cannot eat it yourself - but if you give away the knowledge of how to grow so much grain, then you have helped your society and you can still grow enough grain to eat yourself anyway. So your society is richer and you are not poorer.
