请教：我开空仓3手，平空1时候减了1手，holding应该是-2，为什么显示holding=0呢
平空:SELLSHORT(Pro_trend=1 and HOLDING<0,abs(HOLDING),LIMITR,CLOSE+20*MINDIFF);
平多:SELL(Pro_trend=-1 and HOLDING>0,abs(HOLDING),LIMITR,CLOSE-20*MINDIFF);
开空:BUYSHORT(Pro_trend=-1 and HOLDING=0,3,LIMITR,CLOSE-20*MINDIFF);
开多:BUY(Pro_trend=1 and HOLDING=0,3,LIMITR,CLOSE+20*MINDIFF);

平多1:SELL(Pro_trend=2 and HOLDING=3,1,LIMITR,CLOSE-20*MINDIFF);       
平多2:SELL(Pro_trend=3 and HOLDING=2,1,LIMITR,CLOSE-20*MINDIFF);       
平多3:SELL(Pro_trend=4 and HOLDING>0,HOLDING,LIMITR,CLOSE-20*MINDIFF);       
平多4:SELL(Pro_trend=5 and HOLDING>0,HOLDING,LIMITR,CLOSE-20*MINDIFF);       
平多5:SELL(Pro_trend=6 and HOLDING>0,HOLDING,LIMITR,CLOSE-20*MINDIFF);

平空1:SELLSHORT(Pro_trend=-2 and HOLDING=-3,1,LIMITR,CLOSE+20*MINDIFF);       
平空2:SELLSHORT(Pro_trend=-3 and HOLDING=-2,1,LIMITR,CLOSE+20*MINDIFF);       
平空3:SELLSHORT(Pro_trend=-4 and HOLDING<0,abs(HOLDING),LIMITR,CLOSE+20*MINDIFF);       
平空4:SELLSHORT(Pro_trend=-5 and HOLDING<0,abs(HOLDING),LIMITR,CLOSE+20*MINDIFF);       
平空5:SELLSHORT(Pro_trend=-6 and HOLDING<0,abs(HOLDING),LIMITR,CLOSE+20*MINDIFF);

请提供有效的代码和描述。你上面代码我又没办法运行，我也不知道触发是哪个语句？你输出持仓的语句又在什么位置？基本没有可以判断的有效信息
