I find that grid/DCA is like slowly adding ingredients to a taco: if there's not enough meat, add a little more; if the hot sauce is too much, stop, anyway, I sleep soundly; a quick dart is like being starving late at night and just pouring the whole plate into your mouth, it's satisfying, but the next day your stomach (and mindset) will probably suffer. Recently, I heard that some regions are tightening and loosening tax and compliance policies, and as the expectations for inflows and outflows change, the market fluctuations become more intense, and the "urgency" of the volatility will amplify. At such times, what I pay more attention to is: have I started to refresh frequently, feeling itchy to change my plan. If I can stick to the original script, I use grid/DCA; a quick dart only suits those who already sleep little and are willing to gamble and accept the consequences... I, anyway, am not really good at that.
