The biggest pro of price action trading is that prices are real. What I mean to say is that indicators (ie. MACD, RSI, Stochastics, etc) are just mathematical derivatives of price and are not really there. Price, on the other hand, is the only thing that is real on your chart. And once you learn how to read price you will quickly see who is in control of the market - buyers or sellers - and know which way prices are most likely to go.
