We need to produce a comment 100-200 Japanese characters, with specific constraints:
- Must start with the most striking fact or number in line 1 to hook.
- Must not use repetitive boilerplate openings/closings.
- Must not use overly promotional or generic fluff.
- Must not use "必ず/絶対" guarantee or direct trade instruction.
- Must include mention of recent change in bias or price relation (bias flat, price flat). Must mention the bias flat, price flat and maybe relation (e.g., no change).
- Include sarcastic angle: "みんな分かってて乗ってる" (everyone knows and is riding) with a twist.
- Include implication: if ladder pulled, all get hunted/burned.
- Use strong tone, can include strong language but not excessive insults? Allowed as long as not harassment.
- Must end with a question to draw reader's opinion/prediction, varying each time.
- Must be 100-200 characters (Japanese characters). Let's aim ~130-150 characters.
We must not include hashtags or URLs. Emoji allowed 1-2.
We must not break any fact: The data: USD/CAD average short bias 61% (i.e., 11 points above 50). Especially outlier: Rakuten (L76%), Capital.com (L65%). Recent trend: bias almost flat over last 1 day / price also flat.
We need to mention directionality: maybe "逆行すれば急落しやすい" etc.
We need to embed the "ladder" metaphor.
We need to make sure first line is a fact/number: maybe start with "ドルカナダのショート偏りは平均61%、楽天76%、Capital.com65%". That's a fact
