pinbar 同花顺公式编写

pinbar 是一种常见的技术分析图形，其特征是长影线和短实体，通常用于判断市场趋势的反转和价格的支撑或阻力位。以下是 pinbar 的同花顺公式编写方法：

1. 定义变量

var H, L, C, O, Body, Upper, Lower, Len, Len1, Len2, Len3, Len4;

2. 计算实体、影线和长度

H = REF(HIGH,1);
L = REF(LOW,1);
C = REF(CLOSE,1);
O = REF(OPEN,1);

Body = ABS(C - O);
Upper = H - MAX(O, C);
Lower = MIN(O, C) - L;

Len = ABS(H - L);
Len1 = ABS(C - H);
Len2 = ABS(O - H);
Len3 = ABS(C - L);
Len4 = ABS(O - L);

3. 判断 pinbar 条件

Cond1 = Body < Len * 0.3;
Cond2 = Len1 < Len * 0.3;
Cond3 = Len2 < Len * 0.3;
Cond4 = Len3 < Len * 0.3;
Cond5 = Len4 < Len * 0.3;
Cond6 = Lower < Len * 0.1;
Cond7 = Upper < Len * 0.1;
Cond8 = REF(Body, 1) > REF(Len, 1) * 0.5;

Pinbar = Cond1 AND (Cond2 OR Cond3) AND (Cond4 OR Cond5) AND Cond6 AND Cond7 AND Cond8;

4. 输出结果

SETSTYLE(Pinbar, DRAWSTYLE_HISTOGRAM);
SETBKCOLOR(Pinbar, RGB(128, 128, 128));

以上是 pinbar 的同花顺公式编写方法，可以根据自己的需求进行调整和优化。
