このエラーが見つかりましたが、理由がわかりません (構文は C に似ています)。

関数は売り注文で買い注文を閉じることになっていますが、私は.
error 3: invalid trade parameters

間違って設定しているパラメータはありますか?

以前に正常に呼び出したことがあるので、正しいOrderClose()と思います。OrderSend()

void closeBuySell(int buyTicket){
   double buyPrice = OrderClosePrice();
   //Print("total ",OrdersTotal()," ",buyTickets," ",sellTickets);
   for(int Counter=0; Counter<OrdersTotal(); Counter++){ //search for a matching sell
      if(OrderSelect(Counter,SELECT_BY_POS) && OrderType()==OP_SELL && OrderOpenPrice()>buyPrice){
         Print("CLOSING BUYSELL ",buyTicket," ",OrderTicket()," ",OrderOpenPrice(),">",buyAsk);
         if(OrderCloseBy(buyTicket,OrderTicket(),Red)){ buyTickets--; sellTickets--; }
         else Print(ErrorDescription(GetLastError()));
         break;
      }
   }
}

int buyTickets=0;
int sellTickets=0;
bool up = false;
void OnTick(){
   double FastMA = iMA(NULL,0,FastMAPeriod,0,0,0,0);
   double SlowMA = iMA(NULL,0,SlowMAPeriod,0,0,0,0);
   if(FastMA>SlowMA && !up){ up=true;
       if(buyTickets<15 && OrderSend(Symbol(),OP_BUY,.1,Ask,40,0,0))
           buyTickets++;
   }
   if(FastMA<SlowMA && up){ up=false;
       if(sellTickets<15 && OrderSend(Symbol(),OP_SELL,.1,Bid,40,0,0))
           sellTickets++;
   }

   for(int Counter=0; Counter<OrdersTotal(); Counter++) //ordercloseby buy with sell
      if(OrderSelect(Counter,SELECT_BY_POS) && OrderType()==OP_BUY)
          closeBuySell(OrderTicket());
}

出力：

はい、いくつかの詳細を変更する必要があります。

公正な通知、注意してください、言語でMQL4はありませんC- 要するに -stringは実際には ではありませんstringがstruct、コンパイルモードは、代数式の演算子の優先順位を静かに変更します (!!) (「機械的に」括弧によって強制されない場合)ほとんど目に見えない指示によって曖昧に制御され#property strict、同様の危険な違いが適用されます。

マイナーな問題、いわゆる成行注文には有効期限パラメーター設定がありません。これらは「市場で」すぐに実行されるため、有効期限の TimeDOMAIN-horizo​​n はこれらには意味がありません。

関数にアクセスする前に必須の手順を忘れているようですdb.POOL-OrderSelect()呼び出し:

     if (  FastMA >  SlowMA &&  buyTickets <  15 ){  buy( .1 ); Print(  "buy orders:",  buyTickets ); }
