Moreover, i also discovered that almost all the indicators work best on the long timeframe like weekly or monthly timeframes. If you want making trading decisions with peace of mind? trade only on those timeframes with any indicator and you will make money.
What that matters is what trader are you.
Scalpers will prefer to use the 15 minutes candles instead. But day traders will prefer the 4 hours candles. Swing traders will prefer the 4 hours to a day or 1 week candles. Holders will prefer the monthly candles also.
