功能概述
该指标旨在捕捉“一线天”窄幅震荡后的突破行情。它通过识别股价在特定周期（N=13）内波动幅度极窄（如5%），并在当日强势突破该震荡区间上轨的股票，是一种典型的启动点捕捉策略。
原指标公式源码
N:=13;
一线天筹码:=5;{选股公式-选股指标www.haoyundada.com}
通达信源码:=REF(((HHV(H,N)-LLV(L,N))/LLV(L,N)),1)<=(一线天筹码/100) AND C>=REF(HHV(H,N),1) AND BARSCOUNT(C)>N;
gccdds:IF(通达信源码,1,0);
优化后源码
{ 一线天筹码选股指标 - 优化版 }
{ 核心逻辑：识别窄幅震荡后的强势突破信号 }
N:=13;
一线天筹码幅度:=5; {参数可调：定义窄幅震荡的幅度阈值%}
{ 判断条件：
1. 前一日N周期内振幅小于等于设定的阈值
2. 当日收盘价突破前N周期的最高点（平台高点）
3. 确保数据量足够，排除新股 }
条件判断:= REF(((HHV(HIGH,N)-LLV(LOW,N))/LLV(LOW,N)),1) <= (一线天筹码幅度/100)
AND CLOSE >= REF(HHV(HIGH,N),1)
AND BARSCOUNT(CLOSE) > N;
{ 输出信号 }
一线天筹码信号:IF(条件判断, 1, 0), COLORRED, LINETHICK2;
{ 可视化增强 }
DRAWICON(一线天筹码信号, 0.8, 25); {在信号出现处添加图标}
STICKLINE(条件判断, 0, 1, 1, 0), COLORRED; {用柱状线突出显示信号K线}风险提示
“一线天”形态是典型的突破策略，但在极端行情或低成交量下可能存在假突破风险。本指标基于历史数据回测，信号出现不代表未来必然上涨。AI策略模型由人工智能生成，旨在提供一种量化选股思路，仅供学习与研究之用，不构成任何投资建议。据此操作，风险自负。
