The Holy Grail in forex is...
No such thing in forex. Sorry.
But let's talk about the golden rule in forex trading: form your own opinions about what is happening in the forex market and trade based on your own analyses.
Many inexperienced forex traders are constantly looking for some "guru" to give them the "secret" to striking it rich in forex, to regularly fill their heads with his valuable analysis and market commentary. And they, like sheep, follow him to... the abyss. Others still, having failed to find a guru, go to forums and follow the advice of their brothers in inexperience, seeking a confirmation of their own ideas. It's one thing to want to compare your views on the direction of a currency pair, and quite another to look for confirmation and even approval. Some people prefer to accept other people's opinions as their own, rather than form their own opinions.
