I just found out about your brother. although I don't come here so often anymore I was the creator of the precursor to this board (which existed on Raging Bull) and have known Bob since the early days of that board.
This is profoundly sad news. From the beginning he was a true "presence" both in terms of his understanding of the markets and his desire to share with others. Whenever I came back here I would look for his posts first...... I'm very sorry I never had a chance to meet him.
I can say without exaggeration that he made a real difference to my life. He introduced us all to Hurst and was ever ready to help us work with that system. It was this which, in large part, made my trading what it is today.
My profound condolences to you and all his family - he will be greatly missed.
