Beginners often search for "Forex strategies that work". If that sounds like you right now, then ask yourself: what exactly does that mean to you?
A strategy that "works" for one trader may be utterly boring to a more day trading oriented mind. Likewise, a strategy that might be well suited to an active day trader might be a heart-pounding mess of mistakes, emotional breakdown, and health hazards for a mind that's more well suited to longer term swing or position trading.
Beyond all that trading psychology mumbo jumbo, also remember that it takes a certain level of skill (which may be a lot, or not as much) for each strategy to actually be effective (read: net profitable) over time for a particular trader. Sometimes, it simply can't be avoided that some of these factors go beyond your personality or preferences. Sometimes, it's simply a matter of whether you're experienced enough as a trader in the Forex markets to truly and effectively apply a set of skills.
In the end, what really matters is just one thing: Does your strategy actually give you a statistical edge greater than a 50/50 coin toss? If not, then you might as well save yourself the brain power and start tossing coins to decide whether to go long or short a currency pair. If the strategy does yield a real edge, then learn it, know its strengths and weaknesses, and stay disciplined. Then trade it when it's appropriate, or trade another strategy that might be more appropriate for recent market conditions, and... well, rinse and repeat.
Good trading to all!
