Is there anyone who can code this Metastock formula to Ninja Trader?

Sum(If(C>Ref(C,-1),1,0),5)<Sum(If(C<Ref(C,-1),1,0),5)

Sum(If(C>Ref(C,-1),1,0),5)>Sum(If(C<Ref(C,-1),1,0),5)


Someone explained:

1. If(C>Ref(C,-1),1,0) - If current close is greater than previous close then 1 else zero.
2. Sum of 1 for last 5 periods (i.e. sum of either 1 or 0 from point 1 result)
3. If(C<Ref(C,-1),1,0) - If current close is less than previous close then 1 else zero
4. Sum of 3 for last 5 periods (i.e. sum of either 1 or 0 from point 3 result)
Then
check if 2 < 4 or 2 > 4

Thanks

variables:
DataSeries dsCmpLower;
DataSeries dsCmpHigher;

initialization:
dsCmpLower=new DataSeries(this);
dsCmpHigher=new DataSeries(this);


onbarupdate:

if(CurrentBar>0)
{
dsCmpLower.Set(Close[0]<Close[1] ? 1:0);
dsCmpHigher.Set(Close[0]>Close[1] ? 1:0);
}
else
{
dsCmpLower.Set(0);
dsCmpHigher.Set(0);
}

if(CurrentBar>5)
{
if(SUM(dsCmpLower,5)[0] > SUM(dsCmpHigher,5)[0])
{
// ...code...
}
}
