The only time iv'e had problems with divergence signals is in moderate to strong trends. Divergent signals alone have been very unreliable for me at those times. Seems very accurate in sideways conditions though and well suited for trading those 3 and 5 minute swings.
Certainly appreciate the trend considerations for which you are famous. I look for 'divergence continuation' trades that are in keeping with longer term trend; like the one posted prior to your post.
Having said that, trends have to begin somewhere and, when my conditions are met I'll jump in early on a move against the current trend on that TF.
