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.
I agree with you, Also regardless of what trader are you, Swing, day trader, scalper and holder, what would give you most peace of mind is when you manage your risk, basically when the money involved can be forgotten easily by you should things not go your way, when someone risk money he or she can't afford to lose, that's when a lot things happen.
