When it comes to trading, there are two groups of traders: those who like to use indicators and those who prefer price action only.
Traders who use indicators say they provide accurate entry and exit signals but may sometimes lag. Price action traders argue that indicators rely on price data and thus are unnecessary.
I'd never think there is an accurate tool for trading but the price action that serves as a buy/sell indicator, it could be somewhat effective. But if we still have enough time to explore the market situation, we can use some important trading tools. Besides, this is not about making perfections because this gives us no assurance due to the volatility of the market but at least, we can minimize losses which is one thing we benefit from it.
What do you prefer: price action only or indicators?
Just choose the strategy and tool, or any way of analyzing the market condition that we believe works for us. Our actions come from what we observe in the market price movement which I suggest spending more time with this than on other trading tools.
