[求助]过滤不掉·趋势行情 (文华财经WH8赢智V8.2)

书上说小于20这个值，断定是盘整行情，用KDJ指标操作，结果过滤不掉趋势行情啊？ 

 RSV:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;//收盘价与N周期最低值做差，N周期最高值与N周期最低值做差，两差之间做比值定义为RSV
K:SMA(RSV,M1,1);
D:SMA(K,M2,1);//K值的移动平均
J:3*K-2*D;
CMIVAL:ABS(CLOSE-REF(CLOSE,29))/(HHV(HIGH,30)-LLV(LOW,30))*100,NODRAW;
BACKGROUNDSTYLE(1);
K>D&&EVERY(CMIVAL<20,2),BPK;
CROSS(J,10)||CROSS(K,D),BP;
D>K&&EVERY(CMIVAL<20,2),SPK;
CROSS(90,J)||CROSS(D,K),SP;
