就是boll上軌的值依次變大，或者依次變小

m:=26;

N:=2;

MID :  MA(CLOSE,M);
UPPER: MID + N*STD(CLOSE,M);
LOWER: MID - N*STD(CLOSE,M);

COND:=UPPER>REF(UPPER,1)  AND REF(UPPER,1)>REF(UPPER,2);

cond就是判斷條件

m:=26;

N:=2;

MID :  MA(CLOSE,M);
UPPER: MID + N*STD(CLOSE,M);
LOWER: MID - N*STD(CLOSE,M);

COND:=UPPER>REF(UPPER,1)  AND REF(UPPER,1)>REF(UPPER,2);

cond就是判斷條件

這樣表達是不是一樣的？ ALL(UPPER>REF(UPPER,1),3);
