description: "I just bought a mini position in DRAM today as the starting point for opening a position.I previously bought a 2,000 yuan base position in the STAR Market, and added to it for the first time at today's close.Let's see what happens when the market opens tonight.Additionally, it is generally inadvisable to engage in frequent day trading during sharp declines. The reason is that when everything falls together, emotions are unstable; if you buy in and lose a little, you'll want to cut your losses, but then when the price rebounds, you'll immediately want to buy back in, getting whipsawed by algorithms. This stems from human loss aversion and FOMO (Fear Of Missing Out) psychology.This time, it involves strong leverage due to interest rate hikes and increased margin requirements in South Korea. Having experienced the 2015 Chinese stock market leveraged bull market crash, anyone with some experience knows that US storage stocks are strongly correlated with Korean stocks, so external news has a significant impact on sentiment.The current news suggests the market is panicking over Trump's speech today, which contains many negative factors, including tariffs and decoupling policies towards China."

- **我在丑国爆金币 · 2026-07-17T08:51:37.000Z · 👍 1**: The war continues to escalate, the Fed is hawkish, and Trump is stirring up trouble. With all these moves happening at once, it's best for small retail investors like me to wait for day trading opportunities. Let's see if we can fill the gap below, and if it's a margin call triggered scenario, the d
  - **钢铁纪律** (2026-07-17T08:56:35.000Z): Take it easy. There's actually not much to fear without leverage, but this kind of drop has exceeded the wave in late March.
  - **我在丑国爆金币** (2026-07-17T09:22:25.000Z): Yeah, I still have to thank the big shot for constantly warning about the risks; otherwise, I might have gotten halved in the 2x Hercules.I've never seen a scene like this before. The night session cr

- **汀禾拾金 · 2026-07-17T08:21:15.000Z · 👍 1**: The hero is amazing, starting to open a position during the sharp drop, while I was running away, awkward
  - **钢铁纪律** (2026-07-17T08:47:03.000Z): Because I exited way earlier... Last week, when the night session opened high, I invited a large group to follow. At that time, I specifically posted a thread; if everyone had followed along then, the
- **金先生的交易员 · 2026-07-17T08:18:10.000Z**: I have a few DRAM 50 sell puts expiring at the end of the month; I didn't expect them to drop so fast.
- **豫Chen · 2026-07-17T08:17:28.000Z**: I don't know if I should keep adding to my DRAM position or not; I don't want to add anymore.
