Experience is what that matters most in trading. If you use indicators but you do not have experience in trading, you will lose more often because making profit in trading is not only about indicators. Although the indicators are still very important because it will still help you make good analyses which is their work and not for making profit in trading.
Kinda agreed. Yes its easy to apply those indicators on exchange but a trader must also learn some self attributes like discipline, patience and conviction. Without it, you just following a book blindly. Sometimes theres a need to keep your emotions in check and not be swayed by panic sell that could end up you losing on a trade or frequently hold that supposely be selling already out of greed.
