Three Line Dragon Stock

根据三线均线多头排列和量价配合，筛选涨停或平台突破的强势龙头股，结合多类买入信号进行选股与风控。

Security Scan

The skill is an instruction-only stock-selection guide whose inputs, outputs, and runtime instructions are coherent with its stated purpose and it requests no installs, credentials, or system access.

Purpose & Capability

Name, description and SKILL.md all describe a rules-based stock-selection method (三线均线、多类形态、买入/止损规则). There are no unexpected requirements (no binaries, env vars, or external services) that would be unrelated to stock screening.

Instruction Scope

SKILL.md contains only algorithmic screening rules, signal definitions, filtering steps and risk controls. It does not instruct reading system files, environment variables, or sending data to external endpoints. The listed triggers are keyword-based and limited to invoking the skill.

Install Mechanism

No install spec and no code files — this is instruction-only, so nothing is written to disk or downloaded during install.

Credentials

The skill declares no required environment variables, credentials, or config paths. This is proportional to a guidance/selection-only skill.

Persistence & Privilege

always is false and there is no mechanism that requests persistent system presence or modifies other skills/config. Autonomous invocation is allowed (platform default) but the skill itself does not request elevated persistence.

Assessment

This skill is a rules-based advisory guide (not an automated trading connector). Before enabling: 1) Confirm you will not supply broker/API credentials to the skill — if you later integrate it with trading APIs, re-evaluate for credential and network risks. 2) Treat outputs as trading ideas, not guaranteed signals; backtest or paper-trade the rules first. 3) Be aware of financial/regulatory risk: execution and capital management are your responsibility. If you want the skill to execute trades, expect it to require additional credentials and network access — at that point re-check proportionality and installation details.

一、三线均线系统

参数配置

参数	默认值	说明
MA5	5日均线	短期
MA10	10日均线	主均线
MA20	20日均线	中期

多头排列条件

三线多头 := MA5 > MA10 AND MA10 > MA20 AND MA10持续上升

---

二、四类股票形态

第一类（最强）

条件1 := 涨停 OR 二十日累计涨幅 >= 25%

• 当日涨幅接近涨停
• 或20日累计涨幅>25%
• 量能放大配合

第二类（平台整理后启动）

条件2 := 平台突破 AND NOT(条件1)

• 振幅<8%（横盘整理）
• 低点抬升>15%
• 量能突破（>20日均量1.3倍）

第三类（60日均线附近）

条件3 := NOT(条件1) AND NOT(条件2) AND CLOSE处于MA60的5%区间

• 围绕60日均线波动
• 等待方向选择

第四类（弱势整理）

不符合前三类 → 暂不关注

三、六种买入信号

信号类型	条件	强度
首板涨停	首次涨停+量能配合	⭐⭐⭐⭐⭐
连板回调	3日内2次涨停+回调	⭐⭐⭐⭐
均线交叉买入	股价上穿MA10	⭐⭐⭐
20日新高突破	创20日新高+量能	⭐⭐⭐
平台突破	突破整理平台	⭐⭐⭐
均线回调买入	回踩MA10附近缩量	⭐⭐

首板涨停

首板涨停 := 条件1 AND NOT(REF(条件1, 1))

• 首次涨停，前期非涨停
• 量能配合，三线多头确认

连板回调

连板回调 := COUNT(涨停, 3) >= 2 AND 回调至合理位置

• 3日内至少2次涨停
• 回调至合理位置

均线附近回调买入

回调买入 := 条件2 AND 回调至MA10附近 AND 跌幅 < 3%

• 回踩MA10±2%区间
• 量能萎缩为买入信号

---

四、选股流程

Step 1: 均线多头筛选

• MA5 > MA10 > MA20
• MA10持续上升

Step 2: 涨幅/量能过滤

• 涨停 OR 20日累计涨幅≥25%
• 成交量 > 5日均量1.5倍

Step 3: 形态识别

• 平台整理 → 突破信号
• 回调蓄力 → 回踩买入信号

Step 4: 信号确认

• 量能是关键
• 板块共振优先

---

五、风控要点

仓位管理

• 单票仓位 ≤ 20%
• 弱势信号仓位 ≤ 10%

止损策略

入场方式	止损位置
涨停追入	亏损3%
平台突破	平台下方2%
回调买入	MA10下方3%

注意事项

1. 市场环境优先：大盘上升趋势时成功率更高
2. 板块联动：板块整体强势，个股更可靠
3. 量能验证：无量上涨需警惕
4. 严格执行：信号出现即执行
