hi, good view --
Central bank, backed by other financial institutions (BIS, FMI, agencies...&so on) have a feeling of control over the market, just a feeling ; in the Long run, nothing can go against the herd, even with strong manipulation, like gold and silver i.e. ; see Bank of england sales of their gold reserves at the bottom and buying back at the top!>> this is not control, this is fear...they always get left holding the bag at the end of their dirty scheme, history shows! and it will be the same, when gold will finally spike to the 1000 mark (and that will be just the start of it), due to dollar crash, oil spiking as well and equities finally breaking down....all those markets are controled ot s true, but in short term only ...
As for Spikes in price : it is only the fears and greed of participants, markets are emotionally driven, since manipulation dont work in long term....this is why all market moves are predictable at the start of the move ... if the crowd chose to take that direction, of course, and this is why short term variations are considered Noise... if you understand the market you are trading and its correlation with its environment you know when it will trend and with good timing you can grab at least 80% of its every move...you need to let your emotions flow as well.
cheers
