支撑压力多空系统源码
用法：K线红，信号线红，做多（最高你自己提取特征。这是幼儿园的题目，找出特征。做交易不能懒）。做空反之。
源码如下：
N :=20;
M := 5; //默认3。通道宽
N1:=30;
N1P:=(2*C+H+L)/4;
DEMA_N1_TEMP:= 2*EMA(EMA(N1P,N1),N1)-EMA(EMA(N1P,N1),N1);
HMA:WMA(2*WMA(DEMA_N1_TEMP,ROUND(N1/2))-WMA(DEMA_N1_TEMP,N1),ROUND(SQRT(N1)));
MA30:HMA;
TR1 := MAX(MAX((HIGH – LOW), ABS(REF(C, 1) – HIGH)), ABS(REF(C, 1) – LOW));
UP := H + MA(TR1, N) * M;
DN := L – MA(TR1, N) * M;
L1 := REF(UP, BARSLAST(UP <= REF(UP, 1)));
L2 := LLV(UP, N * 1.5);
LL := IF(L2 <> REF(L2, 1) AND L1 < REF(L1, 1), L1, IF(L1 = L2, L1, L2));
S1 := BARSLAST(CROSS(0.5, UP = LL)) + 1;
S2 := CROSS(COUNT((CROSS(C, LL) OR CROSS(C, REF(LL, 2))) AND UP > LL, S1), 0.5);
A6 := BARSLAST(S2);
B6 := BARSLAST(CROSS(HHV(DN, A6 + 1), C));
BY : =CROSS(B6, A6);
SL :=CROSS(A6, B6);
SUPERTREN :=IF(B6 > A6, HHV(DN, BARSLAST(BY) + 1), LLV(UP, BARSLAST(SL) + 1)), COLORWHITE;
支撑 :IF(B6 > A6, SUPERTREN, NULL), COLORRED, LINETHICK1,DOT;
