請問 open , opend(0) 這二個開盤價的差別? 目前有使用這二種不同的含式且得不不太相同的結果，程式碼如下

程式A

if ((high-low)/close[1])*100>2.5
and open > close
and close * volume > 145000
then ret=1 ;

=====================================

程式B

if (highd(0)-lowd(0))/closd(1)*100 >2.5
and opend(0) > closed(0)
and closed(0) * volume(0) > 145000
then ret=1 ;
