Like the prices atm.
No one on this market does have that kind of ability on knowing on whats the upcoming thing specially on times of correction but somehow with the help of technical analysis then you could presume out possible movements if ever it did reach a certain point like the indicators are already showing off some reversal possible situation
Also to think that not all TA's could really be precise which means it would neither work or follow or wouldn't really make any reactions at all and this is how this market to
unpredictable.
If it was predictable on the first place then we wouldn't really be this big.
