历史回测，怎么是同时买入/平仓呢

   //买入条件
       entry_condition1 = MidLine[1] < MidLine[0];
       entry_condition2 = CrossOver(kValue[0], DValue[0]);


if( MarketPosition<>1 and entry_condition1 and entry_condition2)
{
   buy(lots,Open);
   takeprofeprice = open+win*minmove*pricescale;
   stoplostprice = open-loss*minmove*pricescale;
}
PlotNumeric ("takeprofeprice ",takeprofeprice,0,Red);
PlotNumeric ("stoplostprice ",stoplostprice,0,Green);

//出场
   how_S =T*60;
   for i=0 to how_S
   {
   if( MarketPosition == 1 and High>=takeprofeprice)
{
   Sell(0,max(Open,takeprofeprice));
}

if( MarketPosition == 1 and Low<=stoplostprice)
{
   Sell(0,Min(Open,stoplostprice));
}
}
