This script takes the total NYSE volume for the day and determines what percentage of that volume is Upside Volume (or buying volume).
What's different in this script compared to others is that the 3 most essential values determined by Paul F. Desmond's Dow Award-winning paper for Lowry's Reports are color coded:
1) 90% Upside Volume Day 2) 80% Upside Volume Day 3) 90% Downside Volume Day
According to Paul's award-winning research, these precise criteria are objective definitions of panic selling and panic buying and are generally near major market tops and bottoms.
