@Seraphine_Moyao @TradercBTC 这个数据是哪里来的呢,我一直没有看到学委的公开年化数据(没有否认学委能力,我也看到的国内小帐户的实盘视频,确实很厉害)

I just deleted iTerm2, Warp, and Ghostty from my Mac.
One terminal replaced all three.
It's called Kaku. And it's the first terminal I've used in 10 years that didn't make me configure anything before it felt right.
Here's what makes it different from everything else:
Most terminals give you a blank box and a manual. Kaku opens looking like someone already spent 40 hours setting it up for you. Beautiful fonts, smart autocomplete, colour-coded commands, instant navigation that learns your most visited folders and jumps to them from a two-letter command.
It also boots in half the time of every competitor I tested.
The creator tried Alacritty, Kitty, Ghostty, Warp, and iTerm2. All of them had the same problem: you either got power without polish, or polish without power. So he spent months building the one that ships with both out of the box.
40% smaller than the terminal it's built on. Starts instantly. Never asks you to log in. Never asks for your credit card.
Just download, drag to Applications, and open it.

@Jackal_quant Jackal有空可以讲讲如何理解“ai公司的capex是在内循环”的观点么?虽然市场确实很大,公司也在裁员换用ai,我在公司里也已经是常态化用cc vibe coding代替手搓代码。但想听听你是怎么理解的

截图时间是在上年年底到今年年初nbis 80左右的时候 某个黑子直接在小红书一个data center相关的路人贴给的评论
我看到的时候 两眼一黑,这个人上来直接开骂 而且是专门挑着当时跌幅较重的几个推荐来骂,毫无凭据的造谣说我假Quant 买留言还直接说我是backend operation,🤣
这种掐头去尾的带节奏是纯傻逼,小红书不好骂 在这里我只想说,傻逼东西 继续叫?
我当时看到就截图下来了 心想等到nbis屡破新高的时候来一次打脸贴,这就来了。这一次事情 很好地暴露出一个事实:“造谣带节奏不需要成本,有嘴就行 甚至不需要证据”
这种你跟他论 就像咬狗一口一嘴毛 浪费时间精力还在评论区弄的乌烟瘴气,不争论然后把他拉黑 就在别的地方说心虚 我拉黑他,对于这种没有论据的无意义言论 拉黑不回是任何一个理性的人所做出的最优解
以上是我的个人发泄,但我想说 做一个一直真的在分享干货的博主真的不容易 有很多很多的读者按照我的推荐和路线来现在已经跑赢大盘很多了,请不要在没有任何争取的情况下这样直接开始带节奏攻击
这种行为真的很傻逼和令人无语…

He can cosplay as “pro-China” all he wants.
The second he says “Wuhan virus” instead of COVID-19, the mask slips.
That phrase is not science.
It is racialized propaganda for people who want their prejudice to sound like plain speech.
Elon Musk@elonmusk
The vaccine dosage was obviously too high and done too many times. I had the original Wuhan virus before there was any vaccine and it was much like any other cold/flu. Bad, but not terrible. But my second vaccine shot almost sent me to the hospital. Felt like I was dying.

Two days ago, Anthropic cut off third-party harnesses from using Claude subscriptions — not surprising. Three days ago, MiMo launched its Token Plan — a design I spent real time on, and what I believe is a serious attempt at getting compute allocation and agent harness development right. Putting these two things together, some thoughts:
1. Claude Code's subscription is a beautifully designed system for balanced compute allocation. My guess — it doesn't make money, possibly bleeds it, unless their API margins are 10-20x, which I doubt. I can't rigorously calculate the losses from third-party harnesses plugging in, but I've looked at OpenClaw's context management up close — it's bad. Within a single user query, it fires off rounds of low-value tool calls as separate API requests, each carrying a long context window (often >100K tokens) — wasteful even with cache hits, and in extreme cases driving up cache miss rates for other queries. The actual request count per query ends up several times higher than Claude Code's own framework. Translated to API pricing, the real cost is probably tens of times the subscription price. That's not a gap — that's a crater.
2. Third-party harnesses like OpenClaw/OpenCode can still call Claude via API — they just can't ride on subscriptions anymore. Short term, these agent users will feel the pain, costs jumping easily tens of times. But that pressure is exactly what pushes these harnesses to improve context management, maximize prompt cache hit rates to reuse processed context, cut wasteful token burn. Pain eventually converts to engineering discipline.
3. I'd urge LLM companies not to blindly race to the bottom on pricing before figuring out how to price a coding plan without hemorrhaging money. Selling tokens dirt cheap while leaving the door wide open to third-party harnesses looks nice to users, but it's a trap — the same trap Anthropic just walked out of. The deeper problem: if users burn their attention on low-quality agent harnesses, highly unstable and slow inference services, and models downgraded to cut costs, only to find they still can't get anything done — that's not a healthy cycle for user experience or retention.
4. On MiMo Token Plan — it supports third-party harnesses, billed by token quota, same logic as Claude's newly launched extra usage packages. Because what we're going for is long-term stable delivery of high-quality models and services — not getting you to impulse-pay and then abandon ship.
The bigger picture: global compute capacity can't keep up with the token demand agents are creating. The real way forward isn't cheaper tokens — it's co-evolution. "More token-efficient agent harnesses" × "more powerful and efficient models." Anthropic's move, whether they intended it or not, is pushing the entire ecosystem — open source and closed source alike — in that direction. That's probably a good thing. The Agent era doesn't belong to whoever burns the most compute. It belongs to whoever uses it wisely.

@wu_weitao2975 你好,请教一下,为什么广州是“天然适合”的城市?怎么看广州的荔湾、越秀存在大量混乱的交互场景。还是说瓶颈不在于此?

小马需要意识到,当前在单一城市提高车队密度,比扩展城市重要得多。广州是天然适合的城市,你一百台的速度还是太慢了。

@Jackal_quant 很多这种帖子而且流量会很大,因为这种流量平台记忆天生很短,而且这种极端行为本就吸引研眼球,比如去年暴涨的时候开一次主页能刷到几十个不同的股神,而在这轮震荡里永远不会刷到那批名字里的人,只是换一批极端行为意识流

推荐一本中文交易书加一点我的思考
今年到现在已经读了五六本书。我也没有想到随手拿起了唯一一本中文书“走出幻觉 走向成熟”,居然让我产生了最大的共鸣。作者没有读过大学三十岁就写出了这本书,天赋惊人。下面说几点我觉得非常有价值的点:
*三大traps:逆势重仓短线。我见到账号爆仓的,和我自己接近归零的经历,几乎都可以归结到这三项。重仓包括加杠杆。Jesse Livermore这么多年前就把这个说透了。
* 确定性是无效的。很多人包括自己曾经花了非常多的时间想要追求某种交易的确定性,或者说试图通过增加各种条件来提高交易的成功率,实际上这个都是没有用的。当交易条件增加得很多的时候,最好的交易机会往往就已经被过滤掉了。
* 理解了盈亏同源就不会追求确定性了。实际上追求利润的同时必须要拥抱亏损。一个好的交易策略应该是很多次非常小的亏损和少数非常大的利润。大多数人包括自己在内早期都会抱着亏损的股票等着回本。这个结果是你的正确性可能非常高因为确实有一些回本,但是损失了机会成本,资金卡在亏损的股票很久,同时一定会有非常大的亏损因为有些股票是永远不会回本的。所以如果你交易的正确率特别高的话,往往反而有很大的问题,就应该检查一下自己的回撤了。
* 交易是艺术不是机械的操作,每个decision还是要靠人来决定。所以交易的psychology的控制往往远大于技术层面上的东西。如何进场只是整个系统的非常小的一部分,中间的资金管理stop management和出场哪一个都至少和进场一样重要。
* 人的本性都是抱住亏损见到一点盈利就想跑。所以cut loss let profit run说起来老生常谈,但是因为反人性非常难做到。如果能做到cut loss但是看到一点盈利就跑的话,一样是长期亏损的。因为那些止损掉的小的损失必须要几笔大的盈利去cover,所以miss大的交易盈利会直接影响整个账号。趋势没变的话一定要管住手看着它,不要轻易下车。
* 我自己经过三个阶段。我觉得很多股民也是类似的吧。第一阶段就是不停的在趋势下降的地方接飞刀,还有买便宜股,还美其名曰捡便宜/“价值投资”,承担账号的长期亏损。第二阶段就是我stuck最长的时间,寻找所谓底部盘整的价值股,在它看似要起来的时候买入,这种亏的很少但是总体而言抓了一大把的弱势股,因为都是有过长期跌势的,爬起来困难重重。第三阶段才是敢于对强势股不管股价多高在合适的地方买入。实际上就算在熊市,因为板块轮动的关系,几乎永远有比较强势的股和板块,这些东西技术指标就直接找到了,都不用自己去分析。
* 趋势交易长期而言是越来越钝化的。也就是说在周线和月线上出现的假信号不多但是时间框架越低假信号越多。这也是为什么day trading非常的难,不但要快速的判断和止损还要面对无数的假信号。我个人自认为既没有这个时间也远远没有这个能力。
* 很多时候正确率最高的形态就是经典的形态失效的时候。比如双重底三重底头肩顶这些东西没有按照经典的方式继续走下去,反而走了反方向。这就是典型的大资金投票,或者骗信号,往往继续反向走的可能更高。
* 本书作者很多想法是受到一本书叫Trading your way to financial freedom的启发。我也在看,非常不错。
我之前推荐过大概20本英文的,都很值得一读。

如果不愿意互动,也可以,咱们用钱说话。
我开一个快速通道:如果我开群的话,我会收费60刀/月。但我自己不打算收费,如果你想加我小号,那咱们做点公益。你把这个费用捐给我指定的公益渠道,我加你到我的小号。
我肯定会让你捐给需要帮助的人,你可以对任何人公开我指定的渠道,绝对不给我自己谋半分钱利。
来吧,我看看有多少人愿意花钱!
🎈@Balloon_Capital
给你们展示下什么叫人性! 下面的这个SB,是之前加了我小号的。我在小号里面说的非常清楚:我分享我的仓位和看法,换各位给我大号点赞。但这位一个赞不点,我今天就给从我小号移出了。移出去不到五分钟,他开始在我帖子下面跳脚,说我在带货。 鉴于这个小丑的行为,以及人性的丑陋,以后加我小号的要求提高到收到我10个赞,爱加不加。

@Jackal_quant 另外如果深受xhs的审核困扰,可以考虑知识星球,看到不少人在做,因为是私域审核松一些。但缺点是受众太有限了。只是提供一个思路
中文

@Jackal_quant 1. 通过期指、期权来判断市场trend进行仓位控制是科学、可行的吗;2. 债股汇三市的关系和基于此的分析 3. 前瞻报告里有关于新闻的部分,但如何判断新闻是机构的工具(比如释放利空为了抢筹码)还是真实的预期(比如基本面恶化),新闻先于定价还是滞后,机构肯定有insider

@Ariston_Macro hi 觉得你言之有物,想请教下怎么看待spx收盘站上5日均线,以及你会用什么方式判断站稳呢?(如果认为是白嫖问题可以不回,没关系)
