Here candlestick trading books is a printed material which contains information such as formation of candles what they are, how to trade them and some profitable trading strategy. Going through a book or video tutorial does not really matter.

What matters most is that you get the required knowledge on how to trade the market and become profitable using candlestick.

However learning styles differs, Some traders prefer books while others prefer video tutorial, find out what works best for you and become profitable.
