Toward the end of the book, he says something about finding those levels or points or whatever where buyers are most likely to buy and sellers are most likely to sell, but he puts it better than that. It's in bold, and it's on the left side of the page in the middle. If you can find it, would you mind typing it into a post? It's only three or four sentences. Thx.
There is virtually no use of bold in the book I have (hard covered, NYIF, 1990, ISBN 0-13-215757-8, Barcode 9 780132 157575), only for headings. Certainly no bold sentences on the left side of the page in the middle toward the end of the book.
