@haejin- I have a technical trader I subscribe to for options trading. He often talks about energy built up during consolidation phase to help it make the next move. In the BTS post discussing the possibility of not getting the e leg of the wave, can it be said that hitting the e wave would provide the next wave more energy to make a bigger move or can we even use concept energy (as in physics of waves) in this regard. Is there less energy in only getting a, b, c and d? I'd love to have your feedback given your scientific background and trading experience.
