建立基于布林带和随机指标的实践策略。

应该发生的情况是，如果Close5 分钟柱线的 5 分钟柱线高于上限且随机指标已升至 80 以上，sell则应进入订单，反之则下限 20。

但是，当我运行它进行测试时MT4，我注意到交易非常偏离进场标记（例如，在布林带内而不是在外开盘）。它们不是在Close一根柱线开盘，而是太高或太低几个点。

我究竟做错了什么？

这是我的代码：

extern int    MagicNumber  =  1;
extern double Lots         =  1;
extern double StopLoss     =  5;
extern double TakeProfit   = 15;
extern int    TrailingStop =  0;
       int    ThisBarTrade =  0;

int start() {
   double MyPoint = Point;
   if ( Digits == 3 || Digits == 5 ) MyPoint = Point * 10;

   double TheStopLoss   = 0;
   double TheTakeProfit = 0;

   if ( TotalOrdersCount() == 0 ) {
        if ( Bars != ThisBarTrade ) {
            ThisBarTrade = Bars;
            int result   = 0;
            if (  Open[0] <  iBands( NULL, 0, 20, 2, 0, PRICE_CLOSE, MODE_LOWER, 0 )
               && 20      >  iStochastic( NULL, 0, 12, 1, 3, MODE_SMA, 1, MODE_MAIN, 0 )
               && 0       == OrdersTotal()
               ) // Here is your open [Buy] rule -------------------
            {
               result = OrderSend( Symbol(), OP_BUY, Lots, Ask, 0, 0, 0, "", MagicNumber, 0, Blue );
               if ( result > 0 )
               {
                  TheStopLoss   = 0;
                  TheTakeProfit = 0;
                  if ( TakeProfit > 0 ) TheTakeProfit = Ask + MyPoint * TakeProfit;
                  if ( StopLoss   > 0 ) TheStopLoss   = Ask - MyPoint * StopLoss;
                  OrderSelect( result, SELECT_BY_TICKET );
                  OrderModify( OrderTicket(), OrderOpenPrice(), NormalizeDouble( TheStopLoss, Digits ), NormalizeDouble( TheTakeProfit, Digits ), 0, Green );
               }
               return( 0 ); // JIT/RET --> --> --> --> --> --> --> --> --> 
            }

            if (  Open[0] >  iBands( NULL, 0,  20, 2, 0, PRICE_CLOSE,  MODE_UPPER, 0 )
               && 80      <  iStochastic( NULL, 0, 12, 1, 3, MODE_SMA, 1, MODE_MAIN, 0 )
               && 0       == OrdersTotal()
               ) // Here is your open [Sell] rule -----------------------
            {
               result = OrderSend( Symbol(), OP_SELL, Lots, Bid, 0, 0, 0, "", MagicNumber, 0, Red );
               if ( result > 0 )
               {
                  TheStopLoss   = 0;
                  TheTakeProfit = 0;
                  if ( TakeProfit > 0 ) TheTakeProfit = Bid - MyPoint * TakeProfit;
                  if ( StopLoss   > 0 ) TheStopLoss   = Bid + MyPoint * StopLoss;
                  OrderSelect( result, SELECT_BY_TICKET );
                  OrderModify( OrderTicket(), OrderOpenPrice(), NormalizeDouble( TheStopLoss, Digits ), NormalizeDouble( TheTakeProfit, Digits ), 0, Green );
               }
               return( 0 ); // JIT/RET --> --> --> --> --> --> --> --> --> 
            }
         }
         for ( int cnt = 0; cnt < OrdersTotal(); cnt++ ) {
            OrderSelect( cnt, SELECT_BY_POS, MODE_TRADES );
            if (  OrderType()        <= OP_SELL     // !PENDING ORDER
               && OrderSymbol()      == Symbol()    // !ANOTHER MARKET
               && OrderMagicNumber() == MagicNumber // !ANOTHER EA/MMI TRADE
               )

               }
               else 
               {
                  if ( TrailingStop > 0 )
                  {

在使用iBand()andiStochastic()时，您使用的是SHIFT 0（最后一个参数）。这意味着您正在提取当前（市场边缘）蜡烛的价值。但是，由于当前蜡烛尚未结束，其价值会根据新的传入价格不断变化。这就是为什么您的交易是以看似随机的价格点进行的。

您可能想要的是参考 PREVIOUS（结束）蜡烛，这意味着 SHIFT 应该是 1 而不是 0。
