Based on my own trading outcome, I actually agree with you and this statement.
The thing I am trying to figure out is how to select a good entry. Watching TA and charts did not seem to help. As an example, one chart I have been watching is TEVA. I couldn't find any warning from watching the charts or from all the TA that the stock would drop 25% in one day?
Maybe someone can do a post-hoc analysis and point it out to me.
Thanks.
Standard TA attempts to track price while filtering out noise. Such an approach requires there to be an underlying dynamic of price behaviour. If that was the case it would be possible to estimate the future direction and value of price with some confidence over short timescales. When viewing a chart its easy to fall into the trap of viewing price as a trajectory and through the minds eye or with the assistance of TA, to predict ahead and have an expectation that price will move in a particular way. The problem with that and with any tracking system is the effect of unknown disturbances.
For TEVA the earnings release on 3rd Aug had an impact on price that TA prior to the event could never have accounted for. Although the magnitude of that disturbance was unknown before the event the timing should have been known and factored in any trading plan.
Note that price had fallen over the past year and that especially during the 5 days prior to the earnings release price had dropped - investors anticipating the earnings release.
