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.
When you trade with an amount you can afford to lose, your emotions will always be in check, and as such, your peace is secured, you wouldn't be making outrageous emotional decisions that may warrant you to start losing money.
Do you know that you might be very much certain of a trading set-up but once your emotions is rattled, you wouldn't be at peace and you might even doubt your analysis which might make you pull the plug and pulling out with a loss, in a trade you would have won if you had stayed a little bit longer.
So in essence, what am trying to say is that without your emotions in check, you can never be at peace, that's why it's important to trade with only what you can afford to lose.
