This is a great question and the choice between price action versus trading indicators is a long and hot debated topic. In reality, these two are not as different as they seem. In technical charts, like candlesticks, you get to visualize price action. So, essentially indicators are just another way of using price action to make predictions. Charts just apply formula to the same price action.
I have heard many traders say that indicators are lagging but this is not correct. Yes, indicators take past price action. But traders using price action alone do the same thing. So, both are lagging. To make it less lagging, you can set a shorter timeframe for your charts.
Some traders also believe that using charts is complex. But it is not. If you are with a good broker and on a powerful platform like MT4, you can just drag and drop indicators onto the chart. A good idea is to practice on a demo account. Also, when I joined Axiory, I received a 50% bonus. That added more muscle to my trading account and I could use different indicators across asset classes.
