為什么下一K線開始，才在本K線上顯示出信號？

A:=H/2+L/2 ;
DIFF1:=MA15-MA55;
DEA1:=MA(DIFF1,4);
DIFF2:=MA5-MA55;
DEA2:=MA(DIFF2,4);
KD:=  DIFF2>DIFF1 AND DIFF2>DEA2   AND DIFF2>DEA1 AND DIFF2>0 AND D>MAD AND K>MAK;//開多條件

開多:BUY(KD  AND REF(KD,1) AND H>REF(H,1) AND L>MA10L AND H>MA10H AND THOLDING=0 AND HOLDING=0 AND TIME>091500 AND TIME<151000 ,1,MARKET);          //開多信號
  請幫我看一下，哪個是未來？

把THOLDING改成HOLDING 就行了是吧？
