If I misunderstood you, and you're just pointing out a particularly weak point in OP's analysis, my apologies. But if you doubt TA as a whole: well, guess what? You probably shouldn't actively trade, since that would gambling, wouldn't it? Buy & Hold is your game then, I guess.
Op posted a double top and a macd graph and claims that this is a technical analysis that somehow explains the drop while the drop had nothing to do with anything besides the news from china.
I can show you 100000 double tops before the op's one that meant nothing. When you just get lucky you don't go out to forums and brag "look my TA worked" especially when it is so obvious to everyone about what happened.
