Most of the indicators for forex trading can predict the market movement, accurately on it's historical value and not it current action. Can any forex indicator predict market movement accurately?
Not that accurate but maybe a close one. That indicators is a good reference especially in fiat trades where price is stable. It can't state the right thing to happen but somehow it helps a trader plan their next move.
In cryptos, excluding bitcoin, indicators are nothing since most of the alts are being manipulated due to large hoarders present in that particular alts. Also some of alts devs are just there to make profit.
