Diagram is only for reference and not 100% reliable, that's why I seldom spend much time to study sophisticated diagram. I am really innocent in this respect. I can't deny diagram is a useful tool to provide some guide-lines on the movement trend. My investment stragtegy is exactly what you said short term only according to daily movement trend + risk management. For example, I sold 1 lot @ about 676 this Monday afternoon with preset cut loss @ 680.6 but squared too early @ above 650 that night, though a bit stupid but no regret.
如漲回700+-水平 later, I will do the same again, cause the 700 is a very dangerous zoom, Hedge Funds always wating that movement to action. I will contune to read your diagram analysis which is a useful tool giving me some bright idea where I stand.
