Good question, it's about how much is provided for free, to earn trust, vs more comprehensive in depth training & more alerts etc traders pay for.
Like free samples at Costco, or shareware vs full version software
For example, over 5k traders have registered for my free Saturday webinars, which cover a few great charts, market updates, eventually many go on to join my live room for daily alerts, training and coaching.
Bonus: all week I'm doing free daily 3:30pm 'closing bell' webinars you can join at
