Hello Robert
I called it Vince it is because of his creator
its a man that since age 30 never work a day in his life
just traded stocks
and now in his 70s
it is based on volume
he was charting market on graph paper with
candelesticks
and i spend 6 weeks going to his home to teach him the
computer,
now, 6 month in florida, he takes a lap top
there, and watch and chart market on line,
his gift to me was this indicator
Ben
