經過測試，這句代碼有誤不符合條件，再次發帖求助代碼問題

////////////////

上一根K線的最高價與收盤價、最高價與開盤價價差大于等于10MD時，放空,開倉價格在漲停減去20MD，跌停加上20MD之間

tt:=(time>=090300 and time<145700);

a1:=ref(h,1)-ref(o,1);
a2:=ref(c,1)-ref(o,1);

if tt  then begin
 buyshort (a1>=10*MinDiff and a2>=10*MinDiff and holding=0,1,limit,DYNAINFO( 54)-20*mindiff);
 buyshort (a1>=10*MinDiff and a2>=10*MinDiff and holding=0,1,limit,DYNAINFO( 55)+20*mindiff);

end;

//開空
