SJ:=1;{可自定义参数：macd短周期、长周期、平滑周期}
SHORT:=12; {MACD短周期，默认12，可根据交易周期调整}
LONG:=26; {MACD长周期，默认26，可根据交易周期调整}
MID:=9; {MACD平滑周期，默认9，可根据交易周期调整}
{—————————— MACD核心区域 ——————————}
DIF:(EMA(CLOSE,SHORT)-EMA(CLOSE,LONG))*150,LINETHICK2; {DIF线，放大倍数增强可视化}
DEA:EMA(DIF,MID)*SJ; {DEA线}
DRAWBAND(DIF,RGB(220,160,30),DEA,RGB(60,70,90)); {DIF与DEA间填充色带，橙黄=强势，深蓝=弱势}
{MACD四色变色柱：区分多空+动能强弱}
MACD:(DIF-DEA)*2,COLORSTICK,LINETHICK2;STICKLINE(MACD<REF(MACD,1) AND DIF>0,0,MACD,1,0),COLORBLUE; {多头+动能衰减，蓝色柱}
STICKLINE(MACD>REF(MACD,1) AND DIF>0,0,MACD,1,0),COLORRED; {多头+动能增强，红色柱（强势信号）}
STICKLINE(MACD<REF(MACD,1) AND DIF<0,0,MACD,1,0),COLORLIGREEN; {空头+动能衰减，浅绿柱}
STICKLINE(MACD>REF(MACD,1) AND DIF<0,0,MACD,1,0),COLORLIMAGENTA;{空头+动能增强，品红柱}

RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100; {RSV原始值}
K:SMA(RSV,3,1),COLORBROWN; {k线，棕色线，辨识度高}
D:SMA(K,3,1); {D线，默认色线，辅助判断金叉死叉}
J:3*K-2*D,COLORRED; {J线，红色线，超买超卖信号最灵敏}
