{=============
  参数设置
=============}
N:=9;        {KDJ周期}
M1:=3;       {K值平滑}
M2:=3;       {D值平滑}
VOL_RATIO:=1.5;  {放量倍数}
MA_PERIOD:=20;   {均线周期}

{=============
  计算KDJ指标
=============}
RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;
K:=SMA(RSV,M1,1);
D:=SMA(K,M2,1);
J:=3*K-2*D;

{=============
  成交量条件
=============}

VOL_COND:=VOL>VOL_MA*VOL_RATIO;

{=============
  价格突破条件
=============}
HH:=HHV(HIGH,10);
BREAK_COND:=CLOSE>REF(HH,1);

{=============
  均线确认
=============}
MA20:=MA(CLOSE,MA_PERIOD);
TREND_COND:=CLOSE>MA20;

{=============
  买入信号 (金叉+放量+突破)
=============}
GOLD_CROSS:=CROSS(K,D);
BUY_SIGNAL:=GOLD_CROSS AND VOL_COND AND BREAK_COND AND TREND_COND;

{=============
  卖出信号 (死叉OR止损)
=============}
DEATH_CROSS:=CROSS(D,K);
STOP_LOSS:=CLOSE<MA20*0.95;  {止损线：跌破MA20的95%}
SELL_SIGNAL:=DEATH_CROSS OR STOP_LOSS;
