如何运用CCI指标进行短线买卖操作？

VAR8:=(CROSS(VAR6,VAR7) AND (VAR7 < 16));
VAR9:=((CLOSE > (LLV(CLOSE,60) + (0.3 * LLV(CLOSE,60)))) AND VAR8);
VARA:=IF((CLOSE > 1000),VAR8,VAR9);
黑马起步:=(VAR3 AND VAR4);
逃遁:=VARA;
均线20:=MA(CLOSE,20);
均线120:=MA(CLOSE,120);
牛熊线:=MA(CLOSE,250);
VA:=CROSS(MA(CLOSE,19),MA(CLOSE,120));
VB:=(MA(CLOSE,20) > MA(CLOSE,120));
VC:=CROSS(MA(CLOSE,120),MA(CLOSE,89));
VD:=(MA(CLOSE,20) < MA(CLOSE,120));
VE:=CROSS(MA(CLOSE,20),MA(CLOSE,250));
VF:=(MA(CLOSE,20) > MA(CLOSE,250));
VG:=CROSS(MA(CLOSE,250),MA(CLOSE,20));
DRAWTEXT((((((均线 - REF(均线,1)) > 0) AND CROSS(均线20,均线120)) AND (LOW <= 均线120)) AND (CLOSE >= 均线120)),LOW,'三线开花'),COLORFFFFFF;
