Carney writes it is a smaller, but high probability entry within a pattern. Harmonic breakout he calls it. Entering on the CD line, when the price break the level B of the ABCD towards the PRZ.
What I was looking, the price first of all has to close below the B level of the ABC i.e. the B of the pattern. This is a more agressive entry. On the backtest of the B level there is a less aggressive entry, but in many cases one will miss a straight move to the PRZ. One must see it /test it before committing to this technique. One more comment I remember made about this simpler bamm theory, a higher TF trend does not hurt - as usual.
I attached the previous audnzd example of mine.
I hope it helps.
