New comment
 

Hi,

I am currently adding candlestick pattern for my EA.

herewith i found formula for black hammer/white hammer from our forum. but i want to confirm whether the formula is correct or not?

{
    if ((Close[1] > Open[1]) && (Open[1]-Low[1] >= 2*(Close[1]-Open[1])) && (High[1]-Close[1] <= (Open[1]-Low[1])*0.10))
    {
        Comment("WhiteHammer");
        
    }
}

{
    if ((Close[1] < Open[1]) && (Close[1]-Low[1] >= 2*(Open[1]-Close[1])) && (High[1]-Open[1] <= (Close[1]-Low[1])*0.10))
    {
        Comment("WhiteHammer");
        
    }
}

if its wrong please help me what exact formula to find hammer candlestick?

Thanks in Advance.

  1. Don't write hard to read code like that. That is why you are unsure. Make your code self documenting:
    double bodyBottom = MathMin(Open[1], Close[1]);
double bodyTop    = MathMax(Open[1], Close[1]);
double body       = bodyTop - bodyBottom;
double lowerWick  = bodyBottom - Low[1];
double upperWick  = High[1]    - bodyTop;

bool   isHammer      = lowerWick > 2*body && upperWick < lowerWick*0.10;
bool   isWhiteHammer = Close[1] > Open[1] && isHammer;
bool   isBlackHammer = Close[1] < Open[1] && isHammer;
    Do you have any confusion with any of those lines? Does the formula match?
  2. Second if - black hammer.

Hi,

I never experienced with bool operations. can you support me how to use if conditions for these bool operations. i tried following code, but fails.

{
    if (isWhiteHammer==true)
    {
            
    }
}

if (isWhiteHammer==true)
  1. "fails" is meaningless - just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires - meaningless. There are no mind readers here.
  2. Nothing wrong with that.
  3. You would never write if( (2+2 == 4) == true) would you? if(2+2 == 4) is sufficient. So Don't write if(bool == true), just use if(bool) or if(!bool).

Thank you so much WHRoeder. Works fine here. Thank you for illustrated me like teaching kids. Ofcourse i am Kids in MQL4.. LOL...
