These should be required reading for everyone trading. All the mentors mention it on Profitly. I have Steve Nisons 2 main books in hardcopy and also his course book. My favorite was the course book after reading the other 2. It had quizzes and flash card style reading so you can retain the patterns. This is definitely a little outdated since it's from the 1990's, but the few that are still completely relevant are very important to know. For example, some of my favs as a shortseller are: Gravestone Doji, Evenstar, doji, hammer etc etc. 

Amazingly, there is a free PDF copy of the original 1st book online: http://www.dlinvt.com/pdf/01ucb/ultimatecandlestickbible.pdf

1. Beyond Canlesticks Book

2. Japanese Candlestick Charting Techniques

3. Candlestick Course

These books make it easier to learn. I personally devoted like 2 months to all of this stuff last year around 6/2019. Nison is the man that discovered them in Japan and pioneered them over to stock trading. I wouldn't study the miscellaneous Youtube videos as you will be overwhelmed and confused. There you go, all of the info is right there, together with a free PDF copy of an expensive classic book. How many people will put this to use? Lol probably like 2 at most.
