BuyLimit gives invalid price error

[jadoon88]

Dear Members,

I am trying to write an Expert Advisor with MQL5 that initiates buy limits based on certain EMA values. Here is the code that I have written in OnTick() function.

   MqlRates priceData[]; //create a price array
   
   //sort the array from the current candle downwards
   ArraySetAsSeries(priceData, true);
   
   //copy candle prices for 5 candles into array
   CopyRates(_Symbol, _Period, 0,5, priceData);
   
   //EMA Based Trading
   
   int ema8 = iMA(_Symbol, _Period, 8, 0, MODE_EMA, PRICE_CLOSE);
   int ema21 = iMA(_Symbol, _Period, 21, 0, MODE_EMA, PRICE_CLOSE);
   
   //Arrays to store EMAs
   double ema8Array[], ema21Array[];
   
   
   //Sorting EMAs fot the current candle downwards 
   ArraySetAsSeries(ema8Array, true);
   ArraySetAsSeries(ema21Array, true);
   
   //Defined EMA8, one line, current candle, 5 candles, store result
   CopyBuffer(ema8,0,0,5,ema8Array);
   
   //Defined EMA21, one line, current candle, 5 candles, store result
   CopyBuffer(ema21,0,0,5,ema21Array);
   
   if(ema8Array[0] > ema21Array[0])
   {
      
      if(
      (ema8Array[0] >= priceData[1].close) 
      && 
      (priceData[1].close < ema21Array[0]))
      {
        Print("Chance To Buy"); 
        
        double closePrices[5];
        
        closePrices[0]=priceData[1].close;
        closePrices[1]=priceData[2].close;
        closePrices[2]=priceData[3].close;
        closePrices[3]=priceData[4].close;
        
        if((OrdersTotal() == 0) && (PositionsTotal() == 0))
        {
         int maxValue=ArrayMaximum(closePrices,0,WHOLE_ARRAY);
         double buyStop=closePrices[maxValue]+0.00003;
         double stopLoss=priceData[1].close-0.00004;
         double takeProfit=buyStop+(buyStop-stopLoss);
         
         trade.BuyLimit(0.01,buyStop,_Symbol,0,0,ORDER_TIME_GTC,0,"Limit Added");
        }
      }
      
   }

When I run it it strategy testing with EURUSD on H1 timeline, I get the following error most of the times:

2018.12.25 14:27:47.117 2017.01.02 09:00:09   failed buy limit 0.01 EURUSD at 1.05342 [Invalid price]
2018.12.25 14:27:47.117 2017.01.02 09:00:09   CTrade::OrderSend: buy limit 0.01 EURUSD at 1.05342 [invalid price]

Can you please tell me what I might be doing wrong?

Apologies in advance if this is a very basic question for your precious time, I am new into MQL5 coding and it is hard for me to understand many things. I have read the existing material as much as I can but I still do not understand why I am getting this error. Please help and thank you.

• Pending Order
  Pending order is the client's commitment to the brokerage company to buy or sell a security at a pre-defined price in the future. This type of orders is used for opening of a trade position provided the future quotes reach the pre-defined level. There are four types of pending orders available in the terminal:

• Buy Limit – buy provided the future "ASK" price is equal to the pre-defined value. The current price level is higher than the value of the placed order. Orders of this type are usually placed in anticipation of that the security price, having fallen to a certain level, will increase;
• Buy Stop – buy provided the future "ASK" price is equal to the pre-defined value. The current price level is lower than the value of the placed order. Orders of this type are usually placed in anticipation of that the security price, having reached a certain level, will keep on increasing;
• Sell Limit – sell provided the future "BID" price is equal to the pre-defined value. The current price level is lower than the value of the placed order. Orders of this type are usually placed in anticipation of that the security price, having increased to a certain level, will fall;

Thank you very much. I understand now what I was doing wrong.

I am not a programmer, but I got an EA made on Freelance from someone (this guy is a good person and a programmer, but seems he has hit a snag on this one).

The EA I have got (essentially a grid trading EA):

- Works perfect on demo account

- Gives error on 2 real accounts (I tested this on two real accounts to be sure of this)

EA was tested on same symbol with similar specifications with same broker. Nothing different.

I also checked with broker and they confirmed there are no restrictions / limitations from their end.

Error log from real account is appended below: error is that server gives bid and ask values as 0.00 on real account.  

I would appreciate if one of you can help fixing this.  I will really appreciate it.

Thanks

I am sorry Keith. I did not double post on this thread. It was a different thread.  Irrespective, my bad.

I hope I get the help on above from one of the gurus.

If you want to get help, show your code, you don't have to post all of it, just the part where the bid\ask price is requested.

Trade server return code is 10009, that means the operation was successful!

if(m_trade.Buy(olot,NULL,m_symbol.Ask(),sl,tp,comment))
     {
      if(m_trade.ResultDeal()==0)
        {
         Print("#1 Buy -> false. Result Retcode: ",m_trade.ResultRetcode(),
               ", description of result: ",m_trade.ResultRetcodeDescription());
         dnPrintResult(m_trade,m_symbol);
        }
      else
        {
         lastlvl = m_trade.ResultPrice();
         lastlot = m_trade.ResultVolume();
         Print("last buy level = ",lastlvl);
         Print("#2 Buy -> true. Result Retcode: ",m_trade.ResultRetcode(),
               ", description of result: ",m_trade.ResultRetcodeDescription());
         dnPrintResult(m_trade,m_symbol);
        }
     }

Highlighted yellow, shows where a wrong check is made, the right way to check if a trade operation was successful in MT5 is shown below

if(m_trade.Buy(olot,NULL,m_symbol.Ask(),sl,tp,comment))
     {
      if(m_trade.ResultRetcode()!=10009)
        {

Hi,

as you can see that the trade was successful, and the Result RetCode was 10009.

So, even if we use your code, it will not avoid the trade done at 0.00, right?

Please correct me if I am wrong.

Perhaps you should read the manual, especially the examples.
   How To Ask Questions The Smart Way. 2004
      How To Interpret Answers.
         RTFM and STFW: How To Tell You've Seriously Screwed Up.

They all (including iCustom) return a handle (an int). You get that in OnInit. In OnTick (after the indicator has updated its buffers), you use the handle, shift and count to get the data.

This didn't work.  Bid and ask price still return as 0.00.  Expert tab file attached.
