i believe in price action which can work better than indicator. furthermore, price action is simpler than indicator
Indicators are there to help traders decide their next move. Although called indicators, they actually do not indicate at all where the price will be in the next hours or days. The best that they might provide are price ranges where you could buy or sell.
Trading is not easy of course. The use of indicators are not a guarantee that you will earn. They are just tools to somehow provide guidance on the trader's next move.
What I see about indicators is that they give a trader the idea of where to peg his or her money so that profit is expected. So if you don't make profit all through the trade entered for always, that mean that your indicator is not guiding the trader well and the need for change.
Therefore, indicators are well suited to guide a trader to do better in the risk of his or her money.
