I have always been a fan of looking into my charts using candlesticks. I used it fist when I was trading in the stock market and now I am using it when I trade for altcoins. It is very important to learn how these candlesticks move for you to understand and locate your entry and exit points in trading. But this is just the basics, plainly looking in to the candlestick charts is meaningless if you will mix it up with the studies available. There are a lot but the common studies I use along with my candlestick charts are Bol, MACD and RSI.
