A code in Java and I want to change it to mql5

[miladmiladi]

Hi all

I have a code that give two numbers and its result is a number

it is in java languageand not in Mql5 language. and i want to change it to an indicator that draw a line with result value.

the code is :

        double typed // this variable is input
        double d // this variable is input
        double array[]; // length is 4
        double numArray2[];// length is 4
        double sourceArray[]; // length is 24
        double destinationArray[]; // length is 5
        double numArray5[]; // length is 5
        int numArray1[] = {32,4} // length is 2 and valued
        double num2 = 2.0 * MathRound((MathSqrt(d / numArray1[typed]) / 2.0));
        double num3 = MathFloor(MathSqrt(d));
        double num4 = num3 - num2;
        double num5 = num3 + num2;

        for (int index = 0; true; index++) // the 'true' means that no condition for checking
         { 
                sourceArray[index] = MathPow(num4 + ((num2 * (index + 1)) / 8.0), 2.0);

                if (index > 7)
                {

                        for (int num9 = 8; true; num9++)
                        { 
                                sourceArray[num9] = MathPow(num3 + ((num2 * (num9 - 7)) / 8.0), 2.0);

                                if (num9 > 15)
                                {

                                        for (int num10 = 16; true; num10++)
                                        {
                                                sourceArray[num10] = MathPow(num5 + ((num2 * (num10 - 15)) / 8.0), 2.0);

                                                if (num10 > 23)
                                                {

                                                        for (int num11 = 0; true; num11++)
                                                        {
                                                                if ((d >= sourceArray[num11]) & (d < sourceArray[num11 + 1]))
                                                                {
                                                                        ArrayCopy(sourceArray, num11-5, destinationArray, 0, 5); //
                                                                        ArrayCopy(sourceArray, num11+2, numArray5, 0, 5);
                                                                        for (int num12 = 0; num12 <= 3; num12++)
                                                                        {
                                                                                array[num12] = MathAbs(MathRound((destinationArray[num12 + 1] - destinationArray[num12])));
                                                                                numArray2[num12] = MathAbs(MathRound((numArray5[num12 + 1] - numArray5[num12])));

                                                                        }
                                                                }
                                                                ArraySort(array);
                                                                double num6 = array[0];
                                                                ArraySort(numArray2);
                                                                double num7 = numArray2[numArray2.Length - 1];

                                                                if (num11 > 22)
                                                                {
                                                                        return (8.0 * MathRound(((((16.0 * MathRound((num6 / 16.0))) + (16.0 * MathRound((num7 / 16.0)))) / 2.0) / 8.0))); //
                                                                }
                                                        }
                                                }
                                        }
                                }
                        }
                }
        }
}

The Base code was in C# language. i change it to java and i couldnt change it to Mql5.

Thanks o lot

Best Regards

without diving into code meaning -
it compiles, which seems like a bug in MT5 version 2007 - not all paths return a value, and still compiles ok..
