Need help for a very simple indicator coding

Hi folks,

I want to code a very simple indicator which will print out the result of the following sexy equations :
FirstDerivative[i] = (indicator[i] - indicator[i+1]) / ( iTime(Symbol(), NULL, i) - iTime(Symbol(), NULL, i+1) );
SecondDerivative[i] = (FirstDerivative[i] - FirstDerivative[i+1]) / ( iTime(Symbol(), NULL, i) - iTime(Symbol(), NULL, i+1) );
MyFirstLine[i] = MathExp(FirstDerivative[i]+SecondDerivative[i]);

The Result of the MyFirstLine ought to be printed out, and this derivative must be taken from MA6.The result must be a value between 0 and +infinity.If it's 0<x<1 it's bearish if x>1 bullish I guess.But all i want is to calculate and print out the value in some box on the screen in MT4 nothing else.

Thanks for your time.

Regards.
