Any questions from newcomers on MQL4 and MQL5, help and discussion on algorithms and codes - page 899

[S.P.I]

Good afternoon. I need help, because I don't know how to code, write or modify indicators myself. I will be brief.
Can you add a sound notification (Alert) when
CrossUpchanges from 0.00000 to -1.00000
CrossDown from -1.00000 to 0.00000.
Please help, I will be eternally grateful. Thank you.

Can you add an audible notification (Alert) when the
CrossUpchanges from 0.00000 to -1.00000
CrossDown from -1.00000 to 0.00000.
Help please, I would be eternally grateful. Thank you.

Wrong format, you need mq4

Alekseu Fedotov:

Wrong format, you need mq4

You can also do this with ex4 - resource it and read the buffers.

Artyom Trishkin:

It is possible to do this task with ex4 as well - to resources and read buffers.

Why? standard indicator call from indicator via iCustom(), I think it will take 15-20 minutes, let there be 2 indicator files

There is also iCustom() in resources, but there is one file.

I have two files - let it be two, let it be one. And there is the same amount of work.

That's right, do the math .

Yes, but it is already a percentage of profit, some construction should be done so that the variable drawdown is assigned a value at drawdown, and if the position is in profit, the value drawdown = 0.

   double drawdown=(AccountProfit()<0 ? AccountProfit()*100/AccountBalance() : 0);
   Comment("текущая просадка  = ",drawdown);

Hi, could you tell me how to correctly write the opening of orders from the last fractal. I tried to do it this way, but it doesn't open in the tester.

void CheckForOpen()
{
  
   double hai_candle = iHigh(NULL,TimeCandleTrade,0);
   double low_candle = iLow(NULL,TimeCandleTrade,0); 
   fr_down = iFractals (Symbol(), 0, MODE_LOWER,3);
   fr_up = iFractals(Symbol(),0,MODE_UPPER,3);
   double SL, TP;
  
 if (BuyCount()==0 )
   {
  
    if (fr_down>0 && low_candle<Low[fr_down])
   {
     
      SL = NormalizeDouble(Ask - StopLoss*Point,Digits);
      TP = NormalizeDouble(Ask + TakeProfit*Point,Digits);
      ticket = OrderSend(Symbol(),OP_BUY,Lots,NormalizeDouble(Ask,Digits),Slippage,SL,TP,NULL,magik,0,CLR_NONE);
      if (ticket <0)
       Print ("Не удалось открыть ордер на покупку",GetLastError());
   }
   
   }

int BuyCount()
  {
  int count = 0;
  for (int i=OrdersTotal()-1;i>=0;i--)
  {
    if (OrderSelect(i, SELECT_BY_POS,MODE_TRADES) == true && 
        OrderMagicNumber()== magik &&                        
        OrderType() == OP_BUY )                       
        {
        count ++;
        }
    }
}

You are looking for the fractal on the third bar, it may not be there. Look for the first fractal in the loop.

 
 for (int s=2; s<100; s++) 
     {
    fr_down=iFractals(Symbol(), 0, MODE_LOWER, s);
    if (f!=0) break;
     }
