求助:发布EA时,提示错误 no trading operations

如图,改了好多次。也加入了开仓量和资金余额这些判断条件,还是一直提示这个


有大哥知道怎么办吗


已经再条件中加入了,余额不足和成交量大小的判断:


//| 检测是否有足够的资金交易

//+------------------------------------------------------------------+

bool CheckMoneyForTrade(int type,double lots)

  {

   if(AccountFreeMarginCheck(Symbol(),type,lots)<=0 || GetLastError()==134) return false;

   return true;

  }

//+------------------------------------------------------------------+

//| 检查订单交易量的正确性

//+------------------------------------------------------------------+

bool CheckVolumeValue(double volume)

  {

//--- 交易操作允许的最小交易量

   double min_volume=SymbolInfoDouble(Symbol(),SYMBOL_VOLUME_MIN);

   if(volume<min_volume)

      return false;

//--- 交易操作允许的最大交易量 

   double max_volume=SymbolInfoDouble(Symbol(),SYMBOL_VOLUME_MAX);

   if(volume>max_volume)

      return false;

//--- 取得交易量变化的最小步长

   double volume_step=SymbolInfoDouble(Symbol(),SYMBOL_VOLUME_STEP);

   int ratio=(int)MathRound(volume/volume_step);

   if(MathAbs(ratio*volume_step-volume)>0.0000001)

      return false;

   return true;

  }

"No Trading Operations" Problem - Who can solve this issue forever?!

Pezhman Zamani, 2019.08.10 19:51

I applied major modifications on calculating the lot size and checking the allowed size before OrderSend() based on these modifications. Actually, there was lots of changes. I believe other developers should focus on their own codes to find a solution for their method of programming.

I create a theme for the Developers to see!

I already wrote that in the new requirements - it is mandatory to check for the sufficiency of funds, and if they are insufficient so the work of the EA should be stopped. If the work of EA does not stop so there is the validator error (no trade operations ).

How to use it in the code:

            ticket=OrderSend(Symbol(),OP_SELL,Lot,BID,0,0,0,"",0,0,clrNONE);
            if(ticket<0 && Fun_Error(GetLastError())==1){return;}

//---
           
            ticket=OrderSend(Symbol(),OP_BUY,Lot,ASK,0,0,0,"",0,0,clrNONE);
            if(ticket<0 && Fun_Error(GetLastError())==1){return;}

系統都是根據隨機形式 交易參與者 平台商可能提供的交易條件做測試

既然沒通過 就表示你編的通用性不夠 在某些條件下無法進行自動交易


你自訂義的 CheckVolumeValue(double volume) 只檢查 並沒有"自動修正的功能"

系統提出的條件沒有交易單 就可能是1/. 行情不滿足開單條件 所以沒開單 2/. 開單內容不符合交易規則 所以沒開單
