Does this mean trading bar by bar with typical trade length being 1 bar, or is it just the minimum waiting time for trades at that TF?
No, no, not trading bar by bar, but reassessing the situation bar by bar (before opening position, after opening position , while in position , and even after closing the positione) using the trading method.
And since usually trader uses multiple chart for one instrument with the different scales, where there will be a different situation develop in each scale, therefore trader must reassess situation on multiple charts of the same instrument, again bar by bar.
Trader may have some ideas where the support and resistance are (but the same ideas has almost every participant of the market
), the difference is: the trader has to be able to properly assess those S/R - in which scale to play them out, to view them through and in relationship with other trends and S/R in the vicinity, assessing and reassessing the development bar by bar, especially in accelerating or decelerating price movements.
In light of all that any prediction like "it will (must) go there" - really laughable ... trader does not know when and how price will behave...but he does not need to.
There is an old Wall Street saying: "I have a bad and a good news for you: the bad news is nobody can predict the market; the good news - one does not need to predict the market to make money on it". Imho it is still true.
