Thanks for getting back to me. I'm having a slight crisis here in matching what I've seen on the videos and what shows on my chart.
In the attached chart, the left BP is the BP for that leg from fig. 1 at the top down to the bottom of the swing.
So, if I take the previous swing low point (at the tip of the partly hidden bullish pattern) and draw it through the left BP, e.g. line A-A, it does not come anywhere close to the top of the next swing high point 'C'.
Also, if I draw line B-B through the left BP it also comes nowhere near point 'C'. This is not what I see on the videos, so I must have missed something.
Ok, now for the projection through the right hand BP. which line should I use for this? Line 1-1 or line 2-2? Personally I would chose line 1-1, but I bow to greater experience.
