Most important things is that people should understand they are not into day trade as it requires immense patience and it grit to continue with DCA regardless of market volatility but it went succeed in this then we would see the difference when market booms. I have seen people starting it with passion but once they see market doing good they end up breaking it and going for lump sum investment and starts panicking when the market dumps. You need a clear mindset that you will continue with a fixed amount for x number of years regardless of market situation and this should be an amount which doesn't affect your livelihood.
