Have you looked it on on Kindle?
I sent an email to Howard Bandy and actually got a reply. Really nice guy.
I asked if he would make his books available in Kindle edition, as I really prefer digital books these days, for various reasons: searching later, digital highlighting and bookmarking, less (no) bookshelf space, easier to carry on a plane, read on a beach, etc.
He said he'd investigated creating Kindle format, but the code never rendered well on the Kindle.
AFAIK the only book he has on Kindle (as of this date) is Foundations of Trading: Developing Profitable Trading Systems using Scientific Techniques.
I pointed out that I agreed about the formatting on the Kindle *device*, but I read his Foundations of Trading, and other trading books, on the Kindle *application*, on either my laptop or tablet.
The black and white Kindle also doesn't render colour coded candlestick charts or colour coded programming code well.
So IMO the issue isn't Kindle/digital book formatting, but rather the small screen, black and white Kindle *device*.
AFAIK, as of now, if you want his more in-depth books, you can only get them in physical format.
