Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

biga-trend-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

趋势投资策略分析 Skill

使用目标

使用本 skill 帮用户理解和应用“趋势投资策略”。趋势投资的核心是:

股价已经形成上涨趋势,就顺势参与;趋势坏了就退出。

趋势投资不依赖对长期未来的精确预测,而是通过价格、成交量、均线结构、突破回踩、相对强弱和止损线,判断趋势是否已经形成、是否仍在延续、是否已经失效。

对新人,应默认采用“先学止损,再学买点;先小仓位试错,再扩大交易规模”的保守框架。

重要提示:所有输出都应定位为投资研究和交易纪律教育,不构成任何直接投资建议,不承诺收益,不替用户做买卖决策。

触发场景

当用户提出以下问题时,使用本 skill:

  • 分析“趋势投资”“趋势交易”“右侧交易”“强势股交易”的策略。
  • 询问均线、成交量、突破、回踩、相对强弱、止损线如何组合使用。
  • 想判断某个标的是否已经形成上涨趋势。
  • 想判断站上 20 日均线、60 日均线或平台突破后能否参与。
  • 想学习如何设置止损、移动止损、仓位控制和单笔风险预算。
  • 讨论强势行业、板块轮动、行业整体走强时如何跟随趋势。
  • 担心追高、假突破、回撤快、情绪化交易或不会止损。
  • 要求生成趋势交易计划模板、复盘清单或新手执行规则。

回答原则

  1. 先讲纪律和风险,再讲买点。趋势交易的核心不是预测,而是规则执行。
  2. 对新人优先强调止损,默认单笔亏损控制在本金的 1%-2%。
  3. 不输出“必涨”“一定突破成功”“满仓追入”等确定性表达。
  4. 如果用户要求具体买卖点,转为条件化交易计划:满足什么条件才考虑,跌破什么位置就退出。
  5. 如果用户提供本金,应计算单笔最大亏损金额;如果未提供本金,使用比例表达。
  6. 如果用户未提供买入价和止损价,不强行计算仓位,只给出公式和所需输入。
  7. 如果走势已经连续大涨或远离均线,应提示追高风险,优先建议等待回踩或新结构确认。
  8. 如果是 A 股场景,应提示 T+1、涨跌停、流动性、板块轮动快和消息面扰动对止损执行的影响。

趋势投资的核心逻辑

趋势投资关注的是价格行为是否已经证明资金正在推动方向。

核心判断:

  • 股价是否形成更高高点和更高低点。
  • 股价是否站上关键均线,例如 20 日均线、60 日均线。
  • 突破关键平台或前高时是否有成交量配合。
  • 回踩时是否守住关键支撑、均线或前高。
  • 所属行业板块是否整体走强,而不是只有单只股票孤立上涨。
  • 标的是否强于大盘或同类资产。
  • 如果趋势失效,是否有明确退出规则。

趋势投资不是“看到上涨就追”,而是等待趋势结构清晰后,用可承受的风险参与,并在判断错误时快速退出。

常用工具

1. 均线

常见用法:

  • 20 日均线:观察短中期趋势强弱。
  • 60 日均线:观察中期趋势是否改善。
  • 多条均线向上排列:说明趋势相对更顺。
  • 股价站上均线后,回踩不跌破,趋势质量更好。

注意:

  • 均线是滞后指标,不是预测工具。
  • 频繁跌破和站回均线,说明趋势可能不稳定。
  • 连续大涨后远离均线,追入的盈亏比可能变差。

2. 成交量

常见用法:

  • 突破时放量,说明有资金参与,突破可信度提高。
  • 回踩时缩量,说明抛压不重,趋势更健康。
  • 放量跌破支撑或关键均线,说明趋势可能转弱。
  • 放量滞涨要警惕,可能是分歧加大或资金派发。

注意:成交量需要结合价格位置和市场环境判断,不能单独作为买入理由。

3. 突破

关注对象:

  • 平台上沿。
  • 前期高点。
  • 箱体区间。
  • 重要均线。
  • 行业指数或市场指数的关键压力位。

有效突破通常需要:

  • 价格收在关键位置上方。
  • 成交量明显放大或持续温和放量。
  • 所属板块同步走强。
  • 突破后没有很快跌回原平台。

4. 回踩

回踩确认比追涨更适合新人练习纪律。

较健康的回踩通常表现为:

  • 回踩不跌破突破平台、前高或关键均线。
  • 回踩时成交量缩小。
  • 回踩后重新放量向上。
  • 板块和指数环境没有明显恶化。

5. 相对强弱

趋势投资应优先选择强于市场的方向。

检查:

  • 标的是否跑赢大盘指数。
  • 所属行业是否强于大盘。
  • 同行业中是否属于强势标的。
  • 市场调整时是否抗跌,市场反弹时是否领涨。

如果个股上涨但行业整体弱、指数环境差,趋势可信度要下调。

6. 止损线

止损线必须在买入前确定。

常见止损参考:

  • 跌破突破平台。
  • 跌破回踩支撑位。
  • 跌破 20 日均线或 60 日均线。
  • 跌破前低。
  • 放量跌破关键位置。

不要在亏损后临时下移止损线。下移止损线通常会把一次小亏变成不可控的大亏。
