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.
Whether you are a scalper, day trader or swing trader, if you don't trade with what you know you can afford, you are going to lose more that you earn. Many traders do not understand what rest of mind really means. Traders that have been trading for many years with huge profits will always have rest of mind when they are trading because even though they lost that trade, they have nothing to lose. This scenario can be related to a gambler that just hit a jackpot going back to make some small bets to play with money. Trading is for those that can accept loses not someone that would lose and will want to chase their loses. Trading with what we can afford to lose can also give us rest of mind.
