核心逻辑
这是一个综合型趋势跟踪指标，结合了均线系统、布林带原理和波动率分析。核心思想是通过多条均线的配合来判断牛熊市转换：短期5日均线、中期21日均线、长期250日均线（牛熊线）构成多层次趋势判断体系。同时使用34日波动率指标（VAR3）和21日波动率指标（VAR1/VAR2）来捕捉价格的相对高低位置，识别超买超卖状态。当价格站上21日均线（"界"）时视为多头市场，显示红色K线；跌破则为空头市场，显示黄色K线。
买卖信号
1. **春播（买入）**：ZIG(3,10)指标向上转折且之前处于下降状态，显示"春播"信号，K线变为紫红色 2. **Ｂ点（买入）**：VAR2上穿MA(VAR3,6)时，在最低价下方显示"Ｂ"买入标记 3. **MA5上穿界**：5日均线上穿21日均线时显示"◇底背离"买入提示 4. **秋收（卖出）**：ZIG(3,10)指标向下转折且之前处于上升状态，显示"秋收"信号，K线变为黄色 5. **Ｓ点（卖出）**：MA(VAR3,6)上穿VAR1时，在最高价上方显示"Ｓ"卖出标记 6. **止损条件**：股价触及27日均线（止损线）或13日均线（风险线）时考虑清仓
用法
1. **分批建仓**：当出现"春播"信号时开始关注，首次出现B点时买入第一笔，K线翻红且黄色持股线（21日均线）向上时加仓 2. **持有策略**：股价在21日均线上方运行且K线为红色时一路持有 3. **分批减仓**：出现"秋收"信号时减仓，出现S点时继续减仓，股价跌破止损线或黄色持股线消失时清仓 4. **风险控制**：密切关注13日均线（风险线）和27日均线（止损线），有效跌破需严格止损

1. 买: 春播（注意买入）、B点（加仓）、黄色持股线出现（加仓）、K线翻红（加仓）分三步逐步加仓； 2. 卖: 秋收（注意风险卖）、S点（派发）、股价触及止损线和黄色持股线消失（清仓）分三步逐步减仓； 3. 红色K线一路持有； MA5:MA(CLOSE,5),pointdot,color000000,linethick1; MA21:=EMA(CLOSE,21); MID:MA(CLOSE,21),color000000,linethick0; 风险线: MA(CLOSE,13),linethick3,COLORGREEN; 止损线: MA(CLOSE,27),linethick0,Coloree00ee; UPPER:MID + 2*STD(C,20),LINETHICK0,COLORFFFFFF; LOWER:MID - 2*STD(C,20),LINETHICK0,COLORFFFFFF; H1:=EMA(SLOPE(CLOSE,34)*20+CLOSE,75); H2:=EMA(CLOSE,8); Var1d:=H2-H1; a:=(3*c+l+o+h)/6; b:=(20*a+19*ref(a,1)+18*ref(a,2)+17*ref(a,3)+16*ref(a,4)+15*ref(a,5)+14*ref(a,6)+13*ref(a,7)+12*ref(a,8)+11*ref(a,9)+10*ref(a,10)+9*ref(a,11)+8*ref(a,12)+7*ref(a,13)+6*ref(a,14)+5*ref(a,15)+4*ref(a,16)+3*ref(a,17)+2*ref(a,18)+ref(a,20))/210; d:=ma(b,10); STICKLINE((MA21 > REF(MA21,1)),MA21,MA21,5,6),LINETHICK2,Color00FFFF; STICKLINE(C>=MID AND C>=O,C,O,5,0),COLORRED; STICKLINE(C>=MID AND C>=O,H,L,0,0),COLORRED; STICKLINE(C>=MID AND C<O,C,O,5,1),COLORRED; STICKLINE(C>=MID AND C<O,O,H,0,0),COLORRED; STICKLINE(C>=MID AND C<O,C,L,0,0),COLORRED; STICKLINE(C<MID AND C>O,C,O,5,1),COLORffff00; STICKLINE(C<MID AND C<=O,C,O,5,1),COLORffff00; STICKLINE(C<MID AND C<=O,H,L,0,1),COLORffff00; STICKLINE(C<MID AND C>O,C,H,0,1),COLORffff00; STICKLINE(C<MID AND C>O,O,L,0,1),COLORffff00; 牛熊线:EMA(C,250),CIRCLEDOT,color999999; 界:MA(CLOSE,21),,pointdot,color000000,linethick0; VAR1:=(100 - ((90 * (HHV(HIGH,21) - CLOSE)) / (HHV(HIGH,21) - LLV(LOW,21)))); VAR2:=(100 - ((90 * (HHV(HIGH,21) - CLOSE)) / (HHV(HIGH,21) - LLV(LOW,21)))); VAR3:=(100 - MA(((100 * (HHV(HIGH,6) - CLOSE)) / (HHV(HIGH,6) - LLV(LOW,6))),34)); DRAWICON(crOSS(VAR2,MA(VAR3,6)),(LOW * 0.95),4),linethick3; DRAWICON(CROSS(MA(VAR3,6),VAR1),(HIGH * 1.05),5),linethick3; DRAWTEXT(CROSS(VAR2,MA(VAR3,6)),(LOW * 0.988),'Ｂ'),coloryellow,linethick3; DRAWTEXT(CROSS(MA(VAR3,6),VAR1),(HIGH * 1.02),'Ｓ'),colorFFFF34,linethick3; STICKLINE(C>=界 AND C>=O,C,O,5,0),COLORRED; STICKLINE(C>=界 AND C>=O,H,L,0,0),COLORRED; STICKLINE(C>=界 AND C<O,C,O,5,1),COLORRED; STICKLINE(C>=界 AND C<O,O,H,0,0),COLORRED; STICKLINE(C>=界 AND C<O,C,L,0,0),COLORRED; STICKLINE(C<界 AND C>O,C,O,5,1),COLORffff00; STICKLINE(C<界 AND C<=O,C,O,5,1),COLORffff00; STICKLINE(C<界 AND C<=O,H,L,0,1),COLORffff00; STICKLINE(C<界 AND C>O,C,H,0,1),COLORffff00; STICKLINE(C<界 AND C>O,O,L,0,1),COLORffff00; DRAWTEXT(CROSS(MA5,界),(LOW * 0.90),'◇底背离'),COLORWHITE; VAR11:=(ZIG(3,10) < REF(ZIG(3,10),1)) AND (REF(ZIG(3,10),1) > REF(ZIG(3,10),2)); VAR22:=(ZIG(3,10) > REF(ZIG(3,10),1)) AND (REF(ZIG(3,10),1) < REF(ZIG(3,10),2)); DRAWTEXT(VAR11,HIGH*1.05,'秋收'),COLORYELLOW; DRAWTEXT(VAR22 AND (DATE < 1070804),LOW*0.97,'春播'),COLORFF00FF; STICKLINE(VAR11 AND (DATE < 1070804),CLOSE,OPEN,5,0),COLORYELLOW; STICKLINE(VAR11 AND (DATE < 1070804),HIGH,LOW,0.5,0),COLORYELLOW; STICKLINE(VAR22 AND (DATE < 1070804),CLOSE,OPEN,5,0),COLORFF00FF; STICKLINE(VAR22 AND (DATE < 1070804),HIGH,LOW,0.5,0),COLORFF00FF;
