This is what I'm thinking. We have one of two situations.
1. We are still in wave 5 down and are in wave 2 about to make wave 3. Invalidation is wave 4 - 401.53 2. Wave 5 finished early (Truncated) and we are moving towards A,B,C. Thursday will be a very important day to see structure.
Ultimately, for wave 5 down we will need to continue downward and break previous low.
