Yeah I understand what your saying, I passed many years trying out different strategies, each one seemingly more complicated than the last, and just kept going round in circles.
All the knowledge you need is out there, it's just a case of sifting through the cr@p and getting to whats important.
If I can offer you any advice it's to clear your charts of all the technical indicators you have, pull up a 15min chart of a pair that consists of a strong verses a weak currency, and look at the price action. Look and study the patterns that the candlesticks are making, look at how the price moves and try and understand how these patterns and movements repeat time and time again.
Focus your time and effort on recognising the difference between a trending market and the ranging market, and practice trading using support and resistance lines.
Two simple rules, first is in an
uptrend buy at the break of resistance, second is in a downtrend sell at break of support. I know it doesn't sound very technical but seriously trading is not much more complicated than that, this will put the probability of a trade being successful on your side.
Try it and see what results you get and if you like it start to build up your strategy and rules around it.
When you make your first million remember who told you won't you! lol!!
