請(qǐng)教我想達(dá)到：贏利超過(guò)1%，回吐到70%平倉(cāng)的思路，如下程序卻總是第一次開倉(cāng)、平倉(cāng)是對(duì)的，之后每次開倉(cāng)之后馬上就平倉(cāng)，不知問(wèn)題出在什么地方。

 If enterbars=0 then
 begin
 HigherAfterEntry:=enterprice;
 LowerAfterEntry:=enterprice;
 end;
else If enterbars>=1 then
 begin
 HigherAfterEntry:=max(HigherAfterEntry,h_1);
 LowerAfterEntry:=min(LowerAfterEntry,l_1);
 end;

//開多單的平倉(cāng)
 
 if holding>0 and enterbars>0  then
 
 begin 
if  enterbars>=1  and HigherAfterEntry>=enterprice*(1+1/100)       //成交贏利超過(guò)1%，回吐到70%出場(chǎng)
 then
 begin
 price:=EnterPrice+(HigherAfterEntry-EnterPrice)*70/100;
 if low<=price then
 begin
 sell(1,holding,limitr,min(open,price)) ;
 count2:=1;
 end;
 end; 

//開空單的平倉(cāng)
 
 if holding<0 and enterbars>0  then
 
 begin
 
 
 
 if  enterbars>=1    and lowerAfterEntry<=enterprice*(1-1/100)       //成交贏利超過(guò)1%，回吐到70%贏利出場(chǎng)
 then
 begin
 price:=EnterPrice - (EnterPrice-LowerAfterEntry)*70/100;
 if high>=price then
 begin
 sellshort(1,holding,limitr,max(open,price)) ;
  count2:=1;
 end;
 end;
