Sequential is a long term timing system. It gives very accurate signals but the signal comes in 3-4 months. So it wont be useful for day to day trading. For long term reversals, people who are interested can learn from DeMark or Jesson Pearl books. I can answer the querries and doubts but writing a thread is too much of work.Because it will take lots of efforts as it is not just set up and countdown rules but there are many qualifiers/things to consider to come to the accurate decisions and not sure even 5 guys will be serious in studying it. And those 5 guys will be serious learners and they can learn from the books. Thread on sequential will not be very interesting/ entertaining thread, it will be dull and boring for most people.
