what was the last volume on this day 1928?

Answer 1

I think the word volume is perhaps the wrong word. What is it you mean?

The real issue in 1928 was the ending of the 1920s, growth in the stock market and the effort of the USA to be neutral and isolationist in terms of Europe. Hoover was going to be elected and then in 1929 the roaring twenties would all fall apart.
