New comment
 

hi friends,

am trying to code ma oscillator cross above 0 ubove/below,

there is appearing arrows but i need them at high of the candle(blue arrow) and low of the candle (red arrow),

and also need alert functions in all time frames,

plzz help me,to code

thanks

When I was trying to figure this out I studied the program Fractals - it comes with MT4.

Pay attention to this line of code from Fractals:

ExtUpFractalsBuffer[i]=dCurrent;

Also some arrows will point directly at a price and some arrows will only point close to a price.

Special Arrow codes that exactly points to price and time. It can be one of the following values:

Constant Value Description
1 Upwards arrow with tip rightwards (↱).
2 Downwards arrow with tip rightwards (↳).
3 Left pointing triangle (◄).
4 En Dash symbol (–).
SYMBOL_LEFTPRICE 5 Left sided price label.
SYMBOL_RIGHTPRICE 6 Right sided price label.
 

If you want them exactly at a price, you must use one of the above arrow codes.

Approximately use 

    switch(Period())
    {
        case     1: nShift = 1;   break;    
        case     5: nShift = 3;   break; 
        case    15: nShift = 5;   break; 
        case    30: nShift = 10;  break; 
        case    60: nShift = 15;  break; 
        case   240: nShift = 20;  break; 
        case  1440: nShift = 80;  break; 
        case 10080: nShift = 100; break; 
        case 43200: nShift = 200; break;               
    }

OK, change this . . .

    if (Osma0 > 0 && Osma1 < 0)
    {
      buy [i] = Low [i] - 5 * Point;
      if (Period () >= PERIOD_M30) buy [i] -= 8 * Point;
      if (Period () >= PERIOD_H1) buy [i] -= 8 * Point;
      if (Period () >= PERIOD_H4) buy [i] -= 8 * Point;
      if (Period () >= PERIOD_D1) buy [i] -= 8 * Point;
      if (Period () >= PERIOD_W1) buy [i] -= 12 * Point;
      if (Period () >= PERIOD_MN1) buy [i] -= 60 * Point;
    }
    if (Osma0 < 0 && Osma1 > 0)
    {
      sell [i] = High [i] + 5 * Point;
      if (Period () >= PERIOD_M30) sell [i] += 8 * Point;
      if (Period () >= PERIOD_H1) sell [i] += 8 * Point;
      if (Period () >= PERIOD_H4) sell [i] += 8 * Point;
      if (Period () >= PERIOD_D1) sell [i] += 8 * Point;
      if (Period () >= PERIOD_W1) sell [i] += 12 * Point;
      if (Period () >= PERIOD_MN1) sell [i] += 60 * Point;
    }     
  }

to this . . .

    if (Osma0 > 0 && Osma1 < 0)
    {
      buy [i] = High [i];
    }

    if (Osma0 < 0 && Osma1 > 0)
    {
      sell [i] = Low [i];
    }     
  }

thanks for u r help,

It is a beautiful thing; when you remove lines of code and the program works better.
