Some interesting questions from you,Nick.....all practical trading related.
Perfect scenario:Weekly decline,buy the pivot high break on the daily
Presuming by the time you realised the existence of this stock,that first week denoted by A in your charts is over......Buy on daily when the previous high of Week A is taken out,follow pivot lows as per daily charts.
If even this was missed,look at daily pullback and once prev pivot highs are taken out,get in with a stop at prev pivot lows.
Presuming you have missed the whole run-up,some 5-6 possible entries........look for another opportunity elsewhere!
All the best!
Happy Trading!
