盤後選股腳本問題

我不太會寫請小幫手幫忙補充.  謝謝

// MACD 死亡交叉 

// 

input: FastLength(12), SlowLength(26), MACDLength(9);

variable: difValue(0), macdValue(0), oscValue(0);

SetTotalBar((maxlist(FastLength,SlowLength,6) + MACDLength) * 3 + 8);

SetInputName(1, "DIF短期期數");

SetInputName(2, "DIF長期期數");

SetInputName(3, "MACD期數");

MACD(weightedclose(), FastLength, SlowLength, MACDLength, difValue, macdValue, oscValue);

Ret = difValue Crosses Below macdValue;

1.MACD>DIF

2MACD DIF都要大於0軸
