I'm not defending ICT or saying his concepts work, but some years ago I studied and applied some of his methodology just out of curiosity, like the price engine (grey months/days etc), OSOK setups and his ways to determine a bias for London and NY opening, some of his stuff actually works, I used it in combination with VSA to give myself more confirmation during certain setups.
I agree that his way of teaching is excruciating but if you can get past that, some of his concepts actually work, again I don't trade those as they are.
