Hello

Can somebody help me get tradescript/pi code equivalent of the following amibroker afl?
Many thanks.

SetBarsRequired(sbrAll,sbrAll);
SetFormulaName( “Magic Trend Indicator” );

P = Param(“Period”,20,2,25,1);
m = Param(“Multiplier”,2,0.1,5,0.1);

A = ATR§;

for(i=0;i<P;i++)
{
S[i] = C[i]-m*(A[i]);
T[i] = 1;
}

for(i=P;i<BarCount;i++)
{
if(C[i] > S[i-1])
{
if(T[i-1]==1)
{
S[i] = Max(C[i] - mA[i],S[i-1]);
T[i] = 1;
}
else
{
S[i] = C[i] - mA[i];
T[i] = 1;
}

}
else
{
	if(T[i-1]==-1)
	{
		S[i] = Min(C[i] + m*A[i],S[i-1]);
		T[i] = -1;
	}
	else
	{
		S[i] = C[i] + m*A[i];
		T[i] = -1;
	}
}

}
