You are trying to make it that he only used inside info, and that is not true. He consistently beat bucketshops, and that was as hard to make money as it gets. He was one of the biggest TA trader too. There is a reason he used chalk board kids to keep the prices fresh on his "monitor". His inability to make money in later years can be contributed to lots of things, even being burnt out, not necessary for the existence of SEC.
Hey thats pretty slick. How is that a legal website? https://www.pdfdrive.com/the-art-of-the-deal-by-donald-j-trump-d60374998.html https://www.pdfdrive.com/what-happened-d55285043.html
The book is in the public's domain. Book copyrights are good for 70 years and this was published in 1923. I can't say about the legality of the website though...
Another site, dealing with trading only. Here's the FREE stuff... http://www.forex-warez.com/Free Download/
Out of curiosity I was checking the "How to Trade In Stock" and saw this one which has 224 pages: Then this one with only 80: Is this the same book, just with different editing, font size, etc. ?
Markets change, especially in regards to using volume. Yes, a MA is a MA and a trendline is a trendline but volume is different and trying to apply Livermore's, Wyckoff's, Dow's, etc original trading concepts and theories verbatim in the current markets is going to give sub-optimal results. Were there options and futures which allow one to hide or hedge volume on indexes in the early 1900s? Even in more recent times look at things like NYSE breadth, it more or less became useless with the introduction of etfs. Bid/Ask delta and tape reading became muddled with the advent of Icebergs.
