{=== 参数设置 ===}
SHORT := 12;   {MACD快线周期}
LONG := 26;    {MACD慢线周期}
MID := 9;      {MACD信号线周期}

{=== MACD计算 ===}
DIF := EMA(CLOSE, SHORT) - EMA(CLOSE, LONG);
DEA := EMA(DIF, MID);
MACD_BAR := 2 * (DIF - DEA);

{=== 价格高低点识别 ===}
{最近N根K线的最低价和最高价}
LOW5 := LLV(LOW, 5);
HIGH5 := HHV(HIGH, 5);
LOW10 := LLV(LOW, 10);
HIGH10 := HHV(HIGH, 10);

{判断是否为5日/10日高低点}
IS_LOW5 := LOW = LOW5;
IS_HIGH5 := HIGH = HIGH5;
IS_LOW10 := LOW = LOW10;
IS_HIGH10 := HIGH = HIGH10;

{=== 底背离识别 ===}
{条件：价格创新低，MACD柱状线未创新低}
PRICE_NEW_LOW := IS_LOW5 OR IS_LOW10;
MACD_NOT_NEW_LOW := MACD_BAR > REF(MACD_BAR, BARSLAST(PRICE_NEW_LOW));

BOTTOM_DIVERGENCE := PRICE_NEW_LOW AND MACD_NOT_NEW_LOW AND MACD_BAR < 0;

{=== 顶背离识别 ===}
{条件：价格创新高，MACD柱状线未创新高}
PRICE_NEW_HIGH := IS_HIGH5 OR IS_HIGH10;
MACD_NOT_NEW_HIGH := MACD_BAR < REF(MACD_BAR, BARSLAST(PRICE_NEW_HIGH));

TOP_DIVERGENCE := PRICE_NEW_HIGH AND MACD_NOT_NEW_HIGH AND MACD_BAR > 0;

{=== 买卖信号 ===}
BUY_SIGNAL := BOTTOM_DIVERGENCE AND REF(BOTTOM_DIVERGENCE, 1) = 0;
SELL_SIGNAL := TOP_DIVERGENCE AND REF(TOP_DIVERGENCE, 1) = 0;

{=== 输出显示 ===}
DIF: DIF, COLORWHITE, LINETHICK2;
DEA: DEA, COLORYELLOW, LINETHICK2;
MACD_BAR: MACD_BAR, COLORSTICK;

{=== 买卖标记 ===}
DRAWTEXT(BUY_SIGNAL, MACD_BAR, '买') COLORRED;
