When new traders start out they are bombarded with information. They have to learn about commissions, software, Technical Analysis, stop loss, money management and the list goes on. All this is a handful and that is why Technical Indicators can be helpful for new traders instead of only trading price action. Why is that? Because Technical Indicators gives the new traders fixed rules and parameters in which he/she needs to adhere to. So it gives the trader some structure in this new career. On top of all the information above it is nice to be able to quantify some Technical Indicators that tells the trader exactly when and where to pull the trigger.
Trading is not meant to sound easy because the trader still needs to understand what those particular indicators are telling him/her but it removes the headache of whether or not there is a signal and so on. Price action can sometimes be misinterpreted where this is more rare when trading using Technical Indicators. Removing that stress in the decision making is a great feature as there is plenty of stress regarding the information overload mentioned above. So despite that Technical Indicators are lagging and a derivative of price it can give some much needed structure to the new trader.
It is also easier for the trader to learn to trade when it can be boiled down to Technical Indicators instead of tape reading, news related trades and gut feeling. It is not helpful to the new trader when someone tells him/her that they trade based on news. The trader will not really be able to use that information as it just opens up for a lot more questions such as, what news? Earnings? FDA approval? Also it does not teach the new trader where to place stops as the trade is not based on Technical Analysis.
So Technical Indicators can be great for a new trader as it will help with providing entry, exit and stop loss placement.
