How often do you buy on a down day like today?

I’m not a trader… I’m a novice at technical analysis… of course, when it comes to Bitcoin, it’s all about its fundamentals and just HODLing.

So, in a day like today, when it’s on sale and you want to get as many sats/$ as possible, how do you divide up a cash reserve so as to take advantage of the dip that comes after the dip that followed the dip you were convinced was the bottom?
