It is a form of technical analysis and it uses candles on a chart which represents data. This data shows what the market has been doing for the specified time range. For example if it is a daily candle then it shows what the market did for that day. All economic data and global news that effect price in any way will be reflected on the price chart so it eliminates almost any use of following the news. The main thing that separates price action trading from all other trading strategies is that it uses “clean” or “naked” charts. There are no indicators or anything confusing on your chart, the only thing that is there is raw price displayed as candles. This makes trading simpler and easier to read.
