Hi Monkeyz,
Actually, I don't like trading breakouts at all if I can help it. I've been looking for an entry here though and my original order was placed at 1.6000 (the 61.8% retrace of the 1.5909 to 1.6143 rise) when I figured that 1.5909 was likely to be a wave 4 low. I think I posted this planned trade on this thread. Unfortunately I missed that entry by 0.0002 so the next option was to trade the breakout of the 1.6143 recent high on a 123-low trade so I guess you could say that this time I simply traded the break above 1.6143 rather than the trendline backtest.
Normally I prefer to buy supports, trendline supports and Fibs and to sell resistances, trendline resistances and Fib extensions.
