No, this is: "because everything is already published somewhere..." + + + Even if this was true you have no way of knowing, or more importantly, proving. So to state it as fact is once again ... nonsense.
All perceived PA and the patterns derived from them are binary; Breakout, Failed Breakout, Range-bound true, Range-bound false, Continuation, Change, etc. Iow, it follows through on the basis for the trade idea or it does not. The trade idea has specific criteria pre-defined; What's the bias? Why? What is the specific set-up that one is waiting for? What is the trigger to enter? How much risk taken? Where's the SL? Where's the target? Where are partials taken? If I book a loss, what's the next amount to risk on the next trade? etc. Doing all this on the fly isn't setting up long-term success since there is a lack of data to debrief the trade. Journaling is a broad subject and captures more of the psychological aspects behind trades - logging quantifies it. So in the example of this particular indicator, logging the values of the indicator builds a correspondence of associations. With this one begins to sort indicators through comparison and contrast. Some consider that backtesting, but backtesting in itself is an art & science (what to include, exclude.) ymmv
The best exits are those which provide huge profits in trending markets and only small losses in choppy, range-bound markets.
