I have read some of Nison’s stuff, very informative and very in depth. You may also take a look at the encyclopedia of candlestick formations and patterns. What I particularly like is you can look them up individually and get a percentage rating of its effective.
So with out going into the great depth of Nision and stuffing my brain with a lot of useless information I have narrowed the few patterns down and several candlesticks. of significance.
