N1:=7;N2:=14;N3:=21;

界:=38,COLORFF3311;

STICKLINE(C>0,38,38,1,1),COLORFF9911;

加仓线:=51,COLORFF1155;

STICKLINE(C>0,51,51,1,1),COLORFF1199;

LC:=REF(CLOSE,1);

RSI1:=SMA(MAX(CLOSE-LC,0),N1,1)/SMA(ABS(CLOSE-LC),N1,1)*100,COLORFFFFFF;

RSI2:=SMA(RSI1,7,1),LINETHICK2,COLOR00CD00;

趋势F:=XMA(((CLOSE-LLV(LOW,48))/(HHV(HIGH,48)-LLV(LOW,48))*50),17)+9,COLORFFFFFF;

趋势8:=XMA(((CLOSE-LLV(LOW,53))/(HHV(HIGH,53)-LLV(LOW,53))*50),17)+9,COLOR3377DD;

空头趋势:EMA(((CLOSE-LLV(LOW,38))/(HHV(HIGH,38)-LLV(LOW,38))*50),17)+18,COLORGREEN,LINETHICK2;

多头趋势:XMA(趋势F,7)*1.372,COLORRED,LINETHICK2;

WR2:=多头趋势*1.0887;

WRF:=(1.5*(趋势8+RSI2)-(WR2+多头趋势))+12,COLOR3377FF,COLORRED,LINETHICK2,COLORFF0000;

买:=IF((CROSS(多头趋势,空头趋势)ORCROSS(多头趋势,WRF)AND WRF<界 ANDRSI1<加仓线),48,38),COLORFFFFFF;

XG:=IF((CROSS(RSI1,RSI2)ORCROSS(RSI1,WRF)ANDWRF<界ANDRSI1<加仓线),48,38),COLORFF6655;

错误句 :

买:=IF((CROSS(多头趋势,空头趋势)ORCROSS(多头趋势,WRF)AND WRF<界 ANDRSI1<加仓线),48,38),COLORFFFFFF
