Quote from Ripley:
KEEP it EASY. Anything more, it would get COMPLICATED. The 3rd most important thing to remeber in trading is to STAY AWAY from OVERCOMPLICATION.
No way. Not in this market. You might get away with simple stuff trading microcaps no one's ever heard of that barely break 100K shares/day. But fx will eat this shit alive. Those major moves you want to catch are often 60+pip jumps after news events where no tight stop will stand the volatility beforehand; after that it's chop and slop until the intraday scalpers are exhausted and resign in frustration by the close. You will need to do better than that.
Embrace the complex, embrace uncertainty. Don't depend on repetition to make your living in this market. To exaggerate, if you can't picture a central bank implementing a strategy you're thinking about (ie, buy this or that bar's breakout, sell that 5-min H&S top, whatever), don't bother with it. It won't last.
