With such high volatility, how can I buy without panicking?

How volatile the market has been over the past month or so goes without saying. Storage stocks surge one day and plummet the next, AI hardware is also jumping around, and accounts are following along on a rollercoaster ride—it's quite draining.

How to buy steadily in this kind of market? Let me share my own clumsy methods and also sort out the theories of left-side and right-side trading.

First, left-side trading.
To put it bluntly, it's buying in batches during a downtrend when you think the price has fallen to a point of value. Its advantage is potentially catching the true bottom, with a significantly lower cost than others. But the downside is also obvious—you don't know where the bottom is. You think you're at the floor, but there might be a basement underneath, easily buying too early and getting stuck for a while.
So my own approach is to allocate at most 30% of the position to the left side, buying slowly to leave some room for myself.

Second, right-side trading.
Wait until the price stops making new lows and clearly stabilizes and rebounds, then add the remaining funds. Right-side trading doesn't aim to buy at the cheapest, but to see things more clearly—acting only after the trend has genuinely turned. The advantage is higher certainty, avoiding the agony during the decline; the downside is that the buying price has already risen a bit, possibly missing out on some gains, and if the judgment is wrong, there's also the risk of being lured in by a fake rebound.
So I'm used to leaving most of the position (up to 70%) for the right side, only going in after confirming stability.

Both have their own costs; neither is absolutely better. Some people just like buying more as it falls on the left side, some stubbornly wait for right-side signals—both are fine. The market has no standard answer anyway; finding a rhythm that lets you sleep soundly is what matters most.
