In the first image I see several smaller waves. Some of these are ones I would have traded rather than going for the long play.
I will investigate Rashke. Any pointers to resources would be appreciated.
I noticed that diverging lines often led to similar outcomes but have been unable to identify the conditions which supported such movement.
#3 - I discount those formation with multiple points. In my analysis so far I concentrated only on the clear wedges with strong convergence and no multiple points. There were enough price pairs and TFs from history for me to eliminate all but the most clear signals for studying/analysing. Obviously, such variety and choice is not available moving forward as my broker doesn't provide next month's charts yet.
#4 - The large WW that didn't perform as expected: I take it that 5 was circa April 4th - 6th. Volume was exceptionally low for several days, perhaps Easter holidays. As I said earlier, PA and high volume around 5 seem to be fairly important. If volume drops at this point it would seem better to wait for the price to get to the 2-4 slope before opening the trade even if it means fewer pips.
