原理解析：
X_1赋值:60日前的收盘价=2*60+1日内收盘价最高值
X_2赋值:X_1的60过滤
X_3赋值:BACKSET(X_2,60+1)
X_4赋值:X_3的60过滤
X_5赋值:REF(收盘价,上次X_4距今天数)
X_6赋值:21日前的收盘价=2*21+1日内收盘价最高值
X_7赋值:X_6的21过滤
X_8赋值:BACKSET(X_7,21+1)
X_9赋值:X_8的21过滤
X_10:=REF(收盘价,上次X_9距今天数)
X_11:=(X_5-X_10)/1日前的收盘价*100
X_12:=X_5和X_10较大值
X_13:=(收盘价-X_12)/1日前的收盘价*100
输出DA:X_11>(-10) AND X_11<10 AND (收盘价>X_5 OR 收盘价>X_10) AND X_13<16.18 AND X_13>(-5)
当满足条件DA时,在0.5和25之间画图标
