Using less or no indicator is the best way of trading. The more indicators, you will use, the more confusing they will create. Instead use clean chart and do simple price action trading.
Pure price action isn't easy, sometimes people need the help of indicator, especially people with less experience.
Yes using too many indicator only will causing confused because might occur one indicator already giving signal confrimed but another indicator might still need to waiting signal confirmed, in addition if use complicated indicator which will only causing platform being low responding
why, many idicators can give you more information, if you can handle it properly, why not to use more indicators?
A trader must have a brain, the count of indicators is not so important.
Shhh.... if too many people figure out they need to use their brains in trading, they might start using them in other areas of life. That could destabilize the entire world economy.
